Release Notes

This document lists the most relevant changes, additions, and fixes provided by the latest MeVisLab releases.

Version 3.3 (2020-03)

Fixes / Enhancements (MeVisLab)

  • IDE

    • One can now promote a local macro to a global macro from the context menu of the module.

    • Fields of imported panels in the GUI only allow dragging to/from other fields now if they are exported as internalName on the module of the window.

    • Closing the IDE will now also close all module panels (if MeVisLab should be terminated).

    • Prevent recursive reloading of modules while pressing and holding F5 key.

    • Fixed 'object' not working in console of the PythonObjectInspector - it's '_object' now.

  • TestCaseManager

    • Ask the user if the debugger should be disabled if Python coverage is activated (since only one of these can work at a time).

    • Function parameters can now be passed as dicts (keyword arguments instead of position arguments) to iterative tests in a test case.

    • Improved error handling for secure testing mode.

    • The tearDownTestCase() function is also called for cancelled tests now.

  • MATE (integrated editor)

    • MATE got a dark mode on Windows and Linux (available from the Preferences panel).

    • Added support for mypy besides Pylint (not simultaneously though).

    • Update default Pylint version to install to 2.4.1. Also added inference limit config value, which can improve performance when set to a lower value.

    • For modules with several scripting source files, Pylint (or mypy) is applied to the combined source to improve the output - note that this is only detected if there is an associated module in a connected MeVisLab instance.

    • The Watch area in the Python debugger got a context menu command to remove all watches at once.

    • Improve the behavior of the Python debugger if accessing object attributes to display them in the debugger causes Python exceptions.

  • C++ API changes

    • Added method CSOGeometry::computeClosestPathPoint which really returns the nearest path point of a CSO.

  • Controls

    • Added a tooltipField attribute to all controls, which allows to set the tool-tip of a control through a field.

    • Fixed initial visibility of buttons using the visibleOn attribute in a ButtonBox control.

    • Fixed sorting in ListView control if initial item values are changed later on.

  • Scripting

    • Users can now add a custom entry to the context menu of modules. Just add a .def file with a ModuleAction to your package, which should have a title, condition (a short Python expression) and a userScript attribute. Have a look at the ModuleAction in Packages/MeVisLab/Standard/Modules/Macros/Wizards/LocalToGlobalUserScript/LocalToGlobal.def for an example.

    • Added method enableAlternatingRowColors to the MLABListViewControl.

    • Added method setAllowRenaming to the MLABIconViewControl.

    • One can get the parent Dicom tree of a MLABDicomTree wrapper with parentTree().

    • Added the scripting commands MLAB.prefsFileNames() and MLAB.userPrefsFileName().

    • Allow to set additional image dimension information on an MLWritablePagedImageWrapper with setCDimensionInfos(), setTDimensionInfos(), and setUDimensionInfos().

    • Added deepCopy method to the CSOList scripting wrapper.

    • Fixed MeVisLab hanging when using keyword arguments on a slot that didn't have the kwargs parameter.

    • Fixed the requestStopProcessing call on remote modules to not apply to anything that is sent to the remote module after this call.

    • Changed output of MLAB.detailedSystemId() and MLAB.systemInfo() (at least on some platforms). MLAB.detailedSystemId() is deprecated now, since it actually isn't very detailed. We recommend to use PythonQt.QtCore.QSysInfo instead.

  • Other fixes and improvements

    • One can now set the variable ProfilingTraceFile in the preferences file to employ the profiler from the start to debug startup problems.

    • Added a -printJSONInfo option to the MeVisLabPackageScanner.

  • Third-party libraries

    • Updated Qt to version 5.12.6.

    • Updated libzeromq to version 4.3.2.

    • Added the dcmmkdir tool from the dcmtk library.

    • Python

      • Updated pyzmq to version 18.1.0.

      • Updated jinja2 to version 2.10.3.

      • Updated MarkupSafe to version 1.1.1.

    • SoView2DLabel: Can set margin to background borders.

    • SoView2DOverlayDecoration got an option to draw the border outside the image.

    • Added the updateLayout method to the SoView2D scripting wrapper to update the viewer layout manually.

  • Other Open Inventor modules

    • Make SoMouseGrabber switchable to Managed Interaction, and use that feature accordingly in InteractiveRampLUT and View2D.

    • The SoXxxxMenu menu widgets got a field to control the factor for darkening/brightening on mouse-over.

  • MeVis Path Tracer

    • Added support for IBL_Equirectangular projection to SoPathTracerBackgroundLight (automatically detected from input image).

    • One can select a simple sub-division mode in WEMSubdivide now.

    • Fixed that PVL values were doubled in any WEMProcessor module.

  • ML modules

    • Added a bunch of graph editing modules:.

      • GraphManager: Enables graph editing with undo/redo.

      • LabelTrees: Sets labels to trees in order of descending size.

      • LabelSelectedTree: Sets labels to a selected tree.

      • LabelFromEdgeToLeaves: Sets labels from a selected edge down to the leaves.

      • LabelByThresholdedVolume: Sets labels for image voxel values under the skeleton positions.

      • SetImagePropertiesToGraph: Sets image properties (matrix, image extend) to a graph.

      • GraphToMarker: Converts a graph (nodes, edges) to XMarkers (Positions, Vectors).

      • GraphViewer: Offers a view of the logical structure of a graph.

    • Resample3D: Ensure that the output size is at least 1 in each dimension.

    • VoxelizeInventorSceneGPU works on Radeon cards now.

    • SoImageFileSampler: Added options to generate seamless and Mip-mapped textures.

    • Added the DicomDeidentify module for anonymization of DICOM data.

    • Fixed handling of WindowCenter and WindowWidth for VOI LUT Function "LINEAR" in DicomLUT and RampLUT modules - note: this needs to be enabled in existing networks.

    • LUTCombiner now allows scaling of the input LUTs.

  • Macro modules

    • DicomTool does not write multi-frame information to the individual slices it saves anymore.

Modules and Libraries Provided by Fraunhofer MEVIS

Modules

  • Additions

    • New module NormalizeGeometry for standardization of image geometry (orientation and resolution).

    • New modules for fast and customizable cheapest path search on XMarkerLists (XMarkerListToCostGraph, CostGraphCheapestPath, CostGraphGenericCostPlugin, CostGraphEdgeLengthCostPlugin, CostGraphClosestVertex).

    • New module XMarkerListImageData that reads image data at marker positions and modifies marker properties (vector, type) based on it.

    • New inventor module SoToggleOnResolution allows to toggle scene graphs based on the viewer resolution and/or the viewer ratio.

    • New module CSORemoveSelfIntersection.

    • New GVR extension module GVRGammaCorrection.

    • New module CompareScreenshotsStable.

    • New modules UDPStringSender and UDPStringReceiver for sending and receiving strings over asyncIO UDP sockets.

  • Improvements & extensions

    • DICOM and file IO

      • Several internal quality improvements and minor fixes.

    • PCL

      • The output inspector also displays PCL object information now.

    • Improvements to SimulatedHighDPIViewer:

      • added new rendering mode Offscreen that fixes problems with some inventor modules, such as SoViewportRegion.

      • added event forwarding.

Linux Edition

  • Fixed that MeVisLab could not be started directly from the installer.

macOS Edition

[Note]Note

This release requires at least macOS 10.13 (High Sierra) and Xcode 9.4 for development. macOS 10.15 (Catalina) is not officially supported yet.

  • MeVisLab will provide the root certificates of the macOS system keychain to OpenSSL automatically if none exist at default locations and the environment variable SSL_CERT_FILE is unset. Default locations searched in order are:

    1. ~/Library/Application Support/<BundleName>/Certs/cacert.pem

    2. ~/Library/Caches/<BundleIdentifier>/Certs/cacert.pem (this is the place, where the auto-generated certificates archive is stored)

    3. ~/Library/MLAB_OpenSSL/cert.pem

    4. /Library/MLAB_OpenSSL/cert.pem

  • Allow to setup quick-start permanently via the Preferences panel in MeVisLab.

  • PythonPip macro module installs/updates Python modules into the user's Python library (e.g. ~/Library/MLAB_Python/3.6/lib/python/site-packages) and the integrated Python interpreter loads modules from this location.

  • Store Module Caches outside the installed App Bundle (~/Library/Caches/<BundleIdentifier>/ModuleCache) and watch version to invalidate cache if necessary.

  • Keep dynamic libraries in their original packages when building an App, this will prevent duplicated libraries and reduce App size.

ADK (also known as Application Builder)

  • Support +L? and +?L for optional non-recursive collects in .mli/.mlinstall files.

  • Applications started with -runappbatch don't show the splash screen now.

Version 3.2 (2019-08)

Qt 5.12 update

We have updated our Qt version to 5.12.3. Between Qt 5.6 and Qt 5.12 some things have changed that might need your attention:

  • The (used) license for the Qt libraries is now LGPL 3 instead of LGPL 2.1.

  • The license for the Qt helper tools is now GPL 3 instead of LGPL 2.1, which means you can't link against them (which one doesn't do anyway because they are stand-alone tools) without publishing your code under a similar license. Some of these tools you will use when, e.g., compiling your own C++ modules, but none of them will be included in stand-alone applications by our installer wizards.

  • The qmake tool needed for translating .pro files into platform-specific project files now expects the compiler executable to be on the command-line on Windows and Linux. We tried to make sure that this happens automatically, but in case this doesn't work for your setup you should call the vcvarsall.bat from your Visual Studio installation with argument amd64 before calling the ToolRunner tool or the batch files created alongside the .pro files.

  • The QUrls returned when clicking a non-standard link in the WebView control might have a slightly different string representation than before. If you used this feature you should check if you need to adapt your code to the new format.

Fixes / Enhancements (MeVisLab)

  • IDE

    • Single files listed in the Deployment section of modules do not cause further dependency analysis.

    • Global modules don't have precedence over local macros anymore. Only if no local macro with the given name exists a global macro with the same name is used (and vice versa).

    • One can disable persistence of module panel positions and panel state by setting the DisableModuleWindowsPersistence variable in the preferences file. This helps avoid unnecessary differences in version control systems.

    • Only print package dependency warnings when loading networks in the IDE.

    • Longer enum value lists in the HTML help of a module get a scrollbar.

    • The automatic panel of modules can be opened with Alt+[Shift|Control]+double click and Alt+Enter.

    • Added the facility to display modules with a custom icon (per module type) from a user script that can be selected in the Preferences dialog.

    • Fixed Python debugger updating local variables too late when function locals() (or something similar) is used in code.

    • Automatic reload of modules on double-click also considers changed MDL includes now.

  • TestCaseManager

    • Allow to run GoogleTest tests from a FunctionalTestCase. Example (to be put into a TestCase's python file:

      from TestSupport import CodeTest
      CodeTest.inject("$(MLAB_MeVisLab_Standard)/CodeTests/bin/MLBaseTest", ctx)
      

    • TestCases can decide to display the used sorting literals in the TestCaseManager (by setting showTestFunctionSortingLiterals in the .def file).

    • When typing in the filter line of the TestCaseManager, up and down keys change the selected visible test.

    • You can tell a test to use software rendering with the new keyword preferredRenderer=software (in the .def file of the test) when using secure testing (only on Windows, and on Linux when using the Mesa graphics driver).

    • Tests are by default always run with Secure testing if the environment variable MLAB_USE_SECURE_TESTING_BY_DEFAULT is set.

    • Module help screenshots made on HiDPI screens are now scaled down automatically.

  • MATE (integrated editor)

    • Make dot color (when visible whitespace option is active) configurable.

    • Made the Pylint timeout configurable.

    • Added new keyboard shortcut Ctrl+F3 to find the selected text.

    • Closed documents can be removed from the document session now.

    • Python syntax highlighting in MATE is now more exact with string and number literals. (Did you know that 1.3j is an imaginary number in Python?)

    • One can define and run custom commands from the project workspace context menu now.

    • Fixed and extended Go Back/Go Forward functionality. It now more closely resembles the functionality you may know from, e.g., Visual Studio.

    • Toggling between .script and .py file (default binding is Alt+Down) usually also works now if not connected to a module instance in MeVisLab.

  • C++ API changes

    • The SoPointingAction class can now declare it doesn't want dragMoveTo calls for mouse clicks, even if the mouse was slightly moved during the click.

    • Added a convenience macro SO_NODE_ADD_ENUM_FIELD to the Inventor headers.

    • SoDiagram2DExtensions now have more options in which layer to draw.

    • The AdjustDimInfo<> template was moved from the code of the SubImage module to the MLTools library.

    • Introduced a new ml::OpenGL::getVideoMemorySizeInMB() method which is smarter about returning the texture/video memory actually available in OpenGL.

    • Implemented the Base::deepCopy method on BaseList (and XMarkerList).

    • View2DSliceList::getSliceNormal() always returns the real slice normal (and not just the z vector) now.

    • The SoFieldData::getRemovedFieldNames() method of Inventor nodes is evaluated in MeVisLab now.

  • Controls

    • Added the WebEngineView control, which is similar to the WebView control, but uses the QtWebEngine widget based on Chromium instead of the outdated QtWebKit widget. The new control doesn't allow access to modules, scripting, or module panels of MeVisLab, since the browser engine runs in a separate process, but since the old widget isn't supported anymore we will need to remove the old one in one of the next versions and therefore we urge you to switch if you currently use WebView.

    • The expandY attribute of most controls defaults to auto instead of no now, so you now should rarely need to set this yourself.

    • Added a validator tag to the ComboBox control, which takes a regular expression against which to check the input of an editable ComboBox.

    • Added a insertSeparator method to the ComboBox script wrapper.

    • Added methods setModulePanel and setModuleWindow to the DynamicFrame control.

    • Implemented auto-indentation for the PythonTextView control.

    • Added support for direct texture transfer between processes in RemoteRendering (only on Windows, and on the same computer). Set the useDX11SharedTexture attribute on the RemoteRendering control to activate.

    • Added popupMode = [Instant|Delayed|MenuButton] support to the ToolButton control.

    • Added titleField support to the ToolButton control.

    • Added the acceptWheelEvents tag to some controls — default is true.

    • Added the tag comboEditable to the Field control.

    • Added a componentTitles attribute for Field and VectorEdit controls, and setComponentTitles and setComponentTitleAt scripting methods, which allow to override the default component titles of a vector edit control.

    • Fixed initial visibleOn state of panels included with the Panel control.

    • Added visibleOn expressions for MenuItem entries.

    • visibleOn expressions on controls are evaluated delayed to fix panel layouts growing in size in some situations. This could happen when an intermediate state was used for size calculation where widgets were temporarily visible together that were actually never shown together in practice.

    • Fixed layout flickering on Label controls with a frame and trimming enabled.

    • Added a windowActivatedCommand to the Window control.

    • The ListBox scripting wrapper got a sort method.

  • Scripting

    • When calling unknown methods on objects derived from QWidget a hint is printed that the user perhaps needs to do from PythonQt import QtGui first.

    • We enabled multi-threading in Python. In case of problems you can disable it with an entry PythonMultiThreading = NO in your preferences file.

    • Added MLABModule::callOnGUIThread scripting method to call a scripting function from any thread.

    • The Qt scripting bindings were updated for version 5.12.

    • Added an MLABSoPathField class which allows to access the Inventor node path result of (currently only) module SoPicking from scripting.

    • Removed the method MLAB.macRunPrivilegedCommand.

    • Removed the method MLAB.gpuTextureMemoryInMB, rather use MLAB.gpuVideoMemoryInMB.

    • MLABImageField.mapVoxelToWorld and .mapWorldToVoxel scripting methods also work on the Inventor SbVec3d class now.

    • Added scripting methods for adding and removing vessel voxels to the ml::Graph scripting wrapper.

    • Moved method MLAB.priv().aboutThirdPartyHTML() to MLAB.aboutThirdPartyHTML().

    • The arguments to OpenVDBGridWrapper::toWEM were switched around. If you used this, please adapt your code.

    • Added a new scripting wrapper that allows to find the real nearest point of a WEM triangle mesh (and not just the nearest node of the mesh). Obtain this wrapper with wem.createNearestPointOnSurfaceObject().

    • Fixed that WEMWrapper::removeWEMPatchAt took the argument as id of the WEM instead of as index. Also added WEMWrapper::removeWEMPatchById.

    • Added support for async Python functions in MeVisLab in general and in field listeners and test functions in particular.

    • Added a script wrapper for the MLABRecentFilesHandler, accessible with MLAB.createRecentFilesHandler.

    • Added the MLABTreeWrapper::deepCopy() scripting method.

    • Added scripting method MLABPackageManager.getMeVisPythonExecutable which returns the location of our Python interpreter executable.

    • Added the getTransform method to the scripting wrappers of SbMatrix and SbMatrixd.

    • MeVisLab now changes the PATH on Windows in a way that this change is also visible from Python in os.environ. This fixes that augmenting the PATH from Python would overwrite the changes from MeVisLab, which prevented loading of modules, e.g., after installing and using an externally installed NumPy.

  • Other fixes and improvements

    • We changed our policy on unlicensed use: An unlicensed MeVisLab SDK treats modules signed by non-MeVis owners as unlicensed now.

    • Fixed an issue with too long filenames generated in the Python coverage detection of the TestCenter.

    • Fixed that links to overview documents could not have a different title in mhelp files.

    • DICOM image loading duplicates the value of the PixelSpacing or ImagePixelSpacing tag when this tag only contains one value (thus fixing invalid DICOM files).

    • Project wizards can have a condition (a Python expression) which defines if the wizard should be shown.

    • Make module dependency analyzer detect DLLs from scripting wrappers.

    • Added some DicomTree error logging.

  • Third-party libraries

    • Updated Qt to version 5.12.3.

    • Updated QtWebKit to version 5.212.

    • dcmtk

      • Updated dcmtk to version 3.6.4.

      • Added tools dcmrecv and dcm2pnm to SDK.

    • Updated OpenCV to version 4.0.0.

    • Support for utilizing ffmpeg DLLs has been added to OpenCV on Windows.

    • Python

      • Updated NumPy to version 1.16.4.

      • setuptools has been updated to 40.8.0, pip to 9.0.3.

      • Building the boost Python binding now.

    • Upgraded the Mesa fallback software OpenGL driver for Windows to version 18.1.5.

    • googletest has been updated to version 1.8.1 and googlemock has been newly added.

    • Updated libxml2 to version 2.9.9.

    • Updated libpng to version 1.6.37.

    • Updated OpenSSL to version 1.0.2s.

    • Added a new SoCameraWidget module for moving the Inventor camera from a widget.

    • Added new SoSlideWidget module similar to SoCameraWidget, intended for touch navigation in viewers.

    • SoPicking got a highlighted output flag and can provide two extra pointing actions (because sharing the same sub-scene between different SoPicking modules does not work).

    • SoPicking allows to get the picked color now.

    • Implemented an update mode for the SoSceneLoader module.

    • The AnimatationRecorder has been improved.

  • ML modules

    • Added support for FloatPixelData DICOM tag to ImageSave and ImageLoad.

    • ImageSave can't save RGBA images in DICOM mode anymore, this wasn't done correctly anyway.

    • Added option to only render vessel voxels to the output image of the GraphToVolume module.

    • RemotePanelRendering can render modules in parent networks now (by specifying the "parent:" prefix), not just sibling modules.

Modules and Libraries Provided by Fraunhofer MEVIS

Modules

  • Additions

    • New module ShortestPath for Dijkstra calculation of the shortest path in an image.

    • New python package file_caching that helps when working with slow, possibly remote and unreliable data sources through semi-transparent on-demand caches configured on a per-system level.

    • New (experimental) module CachedPath that wraps some of the file_caching functionality into a macro module.

    • New helper modules Switch2 (switches between exactly two image inputs) and AutoSwitch (auto-switches between one default and an optional 'override' image input).

    • New module CSVReader for reading comma-separated value files.

  • Ported module CLIImporter to Python 3.

  • The ChangeSet Python class would cause an exception when the MeVisLab module on which the class was applied was already deleted when the destructor was called.

  • Fixed some bad handling of OpenGL clip planes (which probably nobody really noticed).

  • Number inputs in module GUIs didn't allow to type in (temporarily invalid) incomplete floating point numbers.

  • MATE: Do not place cursor on previous line when de-indenting.

  • MATE: Python refactoring with rope updated to new version 0.10.7 to fix that extracting a function failed.

Version 3.1 (2018-06)

Python 3 Upgrade

We have upgraded our Python interpreter from Python 2.7 to Python 3.6 in this release. This requires our users to port their Python 2 scripts to Python 3 (if not already done).

To facilitate the porting, we provide the Python futurize library. For more information on porting see Preparing Python Scripts For Python 3.

On Windows, the Python 3 interpreter is now compatible with the official Python 3.6 interpreter. This allows to install binary packages from PyPi (the Python package index). A new PythonPip tool module facilitates the installation of Python packages from PyPi in MeVisLab.

Support for 10bit displays

MeVisLab now supports rendering with 10bit precision (using OpenGL). This requires a graphics card and monitor that support 10bit precision. The support has been tested on AMD/Barco graphics cards and on NVidia quadro graphics cards. We try to auto-detect the support for 10bit, but it can be enabled/disabled by the environment variable MLAB_OPENGL_10BIT as well. If enabled, MeVisLab automatically uses a 10bit capable OpenGL framebuffer (typically a RGB10A2 or RGBA16F buffer). By default, the SoView2D viewer will use a high-precision LUT if 10bit support is enabled. You can see if 10bit support is enabled in the first line of the MeVisLab log (after the graphics card details). It can also be checked in Python using MLABSystemInfo.glSupports10Bit().

Physically-based Path Tracing (CUDA only)

The MeVis Path Tracer offers a state-of-the-art Monte Carlo Path Tracing framework running on NVidia GPUs (CUDA). It supports high-quality physically based rendering of volumes, meshes, thick lines and other geometry. For details, have a look at the MeVis Path Tracer Overview.

OpenVDB integration (sparse grid support)

The OpenVDB library (www.openvdb.org) has been integrated into MeVisLab. OpenVDB supports sparse voxel grids and has a unique level set representation for meshes. It has been used to implement several new MeVisLab modules:

  • CSOToSurface creates a WEM surface from a list of CSOs.

  • MarkersToSurface creates a WEM surface from a marker list by rasterizing the markers as spheres.

  • OpenVDBLoad loads a sparse grid as an ML image volume.

  • OpenVDBSave saves an ML image volume as an OpenVDB sparse grid.

  • VoxelizeCSO, VoxelizeMarkers, and VoxelizeWEM voxelize the respective structures into a reference image coordinate system.

  • WEMLevelSetBoolean allows to perform boolean operations on closed WEM meshes using a level set representation.

  • WEMLevelSetFilter allows to apply a kernel filter on a level set generated from a closed WEM mesh and remesh the result.

  • WEMLevelSetOffset allows to enlarge or shrink a closed WEM using level sets.

  • WEMLevelSetRemesh remeshes a closed WEM using a level set representation.

    • The MeVisLab Output Inspector now supports specialized inspectors for Python object sub-types.

    • Print an error message if a FieldListener has no field or no command given.

    • Fixed CTRL+Tab switching between networks in IDE and files in MATE.

    • Fixed inheriting module documentation if the module name is not the class name.

    • Can avoid per-function result directory by setting perFunctionResultDirectory to False in the .def file of the test.

    • Added option to display test report viewer inside the main TestCaseManager panel.

  • MATE (integrated editor)

    • Newly opened MATE documents are inserted after the tab from which they were opened.

    • MATE now downloads and installs Pylint version 1.8.4 by default.

    • Improved MATE startup performance by doing delayed package loading.

    • The replace-in-files dialog always writes system-specific line endings now.

  • C++ API changes

    • Added new ML list fields: ml::IntListField, ml::DoubleListField, ml::Vector2ListField, ml::Vector3ListField, and ml::Vector4ListField (similar to the Inventor multi-fields).

    • The mlError, mlWarning, mlInfo macros do not need an error type argument anymore. If omitted, ML_BAD_PARAMETER is used.

    • ml::Fields don't have a copy constructor anymore.

    • Added new getInterpolatedValue() method on ml::PagedImage which allows to fetch a tri-linear interpolated value at an arbitrary location.

    • ml::Rotation now creates a 180° rotation for exactly opposite vectors (previously it did nothing).

    • The Inventor class SoEvent now has a mouseButtonMask property that contains the currently pressed mouse buttons.

    • Allow to override existing cursor shapes in Inventor viewers with SoViewerProxy::defineCursor.

    • Added a BLANK_CURSOR value for the cursor shape enum field in Inventor modules.

    • Renamed internal Inventor class SoLightPath to SoLightweightPath because the name was confusing.

    • The destructor of Inventor class SbProjector was made virtual.

    • Added a ML_EXPLICIT_FALLTHROUGH define to all platforms, which expands to [[fallthrough]] (C++17) on platforms where an implicit fallthrough would result in a warning at compile time.

    • Added new method ml::OpenGL::isMesaSoftwareRenderer() to check if MeVisLab runs with an OpenGL software renderer.

  • Controls

    • Added a PythonTextView control for editing Python code in modules. It supports auto-completion of the underlying module context, context sensitive help and an extended context menu. Many modules that offer Python scripting now make use of this control (RunPythonScript, PythonArithmetic, ...).

    • ItemModelView can show a color and a checkbox in the same column.

    • Implemented an alternatingRowColors attribute on ItemModelView.

    • Added alternateBase (needed for alternatingRowColors), toolTipBase, and toolTipText color roles to MDL style.

    • Added clickedColumnField attribute to ItemModelView control, which writes the column index onto which the user (double-)clicked to the given field.

    • Implemented dependsOn/visibleOn on the Row element of the Table control.

    • Added new listview mode on TabView control. This facilitates the creation of preferences-style panel with a listview instead of a tabbar to select tabs. The listview can be made hierarchical by using the tabHierarchy tag on TabViewItems.

    • Fixed initial enabled state of TabView with only one child.

    • Fixed that dependsOn of ButtonGroupControl items always affected the first item.

    • When a parent checkbox in an ItemModelView control switches several child checkboxes, these are collected into one ItemModel update event.

    • Removed slicerScale attribute on Slider control (it didn't work anyway).

    • The Space key is not titled "Any" anymore in the EventFilter control. Also added the numerical "keyCode" info.

    • Call shouldCloseCommand if a modal dialog panel is closed with the Escape key.

    • Use system proxy settings by default in WebView control if no proxy is specified in the Preferences dialog of MeVisLab.

    • The Field control now recognizes the comboItems attribute.

    • Fixed wrong auto-alignment groups on the Grid control. Previously all Grid children got the same width, regardless of their column.

    • The More button on a Field control now shows a non-editable dialog if the control is non-editable.

    • Fixed problem with auto-repeat in step-buttons of number widget if a dialog is opened on value change.

  • Scripting

    • New field wrapper classes for the ML list fields and some Inventor multi-fields: MLABIntegerListField, MLABDoubleListField, MLABVector2ListField, MLABVector3ListField, and MLABVector4ListField.

      Since previously these fields were wrapped with MLABStringField you will now get an info message if you use the old value property which has a string type. You should rather use the new listValue property or stringValue()/setStringValue().

    • Added mlab_projects Python meta package for importing Python modules from MeVisLab module projects. (Not supported in auto-completion!)

      Use

      from mlab_projects.MySuperDuperProject import Utilities
      in Python code to import the Python module Utilities from file $(MyPackage)/Projects/MySuperDuperProject/Modules/Scripts/python/Utilities.py.

    • Added MLAB.cryptStringUTF8()/MLAB.decryptStringUTF8() scripting methods with UTF-8 support.

    • Added setVr method to MLABMutableDicomTag.

    • Python object __object__ in the module context can now be any Python object to be visible through ctx.object(). Previously the auto-conversion of Python sequences or maps caused a conversion to a different object type.

    • The field associated with a control can now be accessed with the field() method.

    • MLABProcess.runCommandInConsole now has an option to wait until finished.

    • Added new scripting methods on macro modules to determine the sub-type (local, ad-hoc).

    • Added scripting method ctx.shouldAvoidSideEffects(), which returns true if a module is created just for editor auto-completion.

    • MLABModule::addModule does not print package dependency warnings anymore.

    • Print an error message if a call on a module could not be performed because there was no script context.

    • Using the MLABHttpDownload scripting class failed for large downloads in the GB range.

    • Added new scripting method MLABFileManager.setApplicationSupportUmbrellaDirectoryName() so applications can select another name than 'MeVis'.

  • Other fixes and improvements

    • Improved CUDA building support, support CUDA 9.

    • Connecting a bool field to float/double fields correctly sets 0 or 1 (only worked for Inventor fields before).

    • Do not ignore legacy values in lazy loading modules.

    • Save persistent flag of fields if required in lazy loading modules.

    • Worker processes (of remote modules) ignore the Logfile variable now.

  • Third-party libraries

    • New module SoView2DInfo that displays SoView2DExtension infos.

    • New module DynamicLayout that creates a layout using an MDL file and embeds viewers found in the connected Inventor graph.

    • New module SoActionFilter that allows to select which actions are applied to the child graph.

    • New module InventorGuard that combines SoIdentifier and SoActionFilter such that the child graph can not be added directly to the scene.

    • New module SoNodeFilter that filters the Inventor scene graph based on node names or types.

    • New module ComposeBoundingBox that calculates a composed bounding box of two aligned images.

    • New module ApplyOrthoOrientation, extending NormalizeOrthoOrientation with an additional "FromReference" mode, which applies the same ortho-orientation (transversal, sagittal, or coronal) as a given reference image.

    • New module OrthoCombination, does a combination of three images in different orthogonal orientations into a single one with a defined orientation, which puts the images from the different inputs in separate sub images in the c, t, or u dimension. This allows for convenient combination using modules requiring a single input image (e.g. OrthoProjection or kernel filtering).

    • New module ApplyGlobalModalityLUT, allowing for normalizing DICOM data containing either a single frame-unspecific (i.e. "shared" or "global") or multiple frame-specific RescaleIntercept or RescaleSlope values to a single, frame-unspecific, user-defined intercept, slope, and data type. (combining ApplyDicomPixelModifiers and DicomRescale).

    • New module BoundingBoxInReferenceSystem that computes the smallest SubImage of input1 that would contain all (reformated) voxels of image0..

    • New module LUTColorAtIndex that gets the color at the given LUT index.

Version 3.0 (2017-06)

The main reason for the change in the major version number is that MeVisLab is now based on Qt5.6. This change also caused some other changes, so you should read the release notes carefully.

Qt5 Porting Issues

  • The clickedCommand and mouseButtonClickedCommand of the ListView control only react on left-click now. If you want to react on right-clicks, use the pressedCommand or an EventFilter.

  • We switched to a new OpenGL widget in Qt. In case of problems you can get back the old widget by setting the environment variable MLAB_QT_OPENGL_WIDGET to old.

  • The (legacy) support for JavaScript scripting in modules has been removed entirely.

  • ActiveX support has finally been dropped entirely.

Python 3 Switch Preparations

We are planning to switch from Python 2 to Python 3 with one of the next releases. To ease the switch we made it possible to make the Python scripting code compatible with both versions.

For this, we introduced a Python 3 Compatibility Warnings option in the Preferences... dialog under the Scripting section. This will emit warnings about non-compatible code when the code is executed. This will also enable warnings about non-compatible code in MATE if Pylint is installed.

There is also a User Script under ScriptingPython 3 SupportFuturize Python Scripts that will automatically convert your code to be compatible with Python 3. It is advisable to check the changes though, since they sometimes tend to be in the category 'works, but is not pretty', and can be done better by a knowledgeable user.

For more information see Preparing Python Scripts For Python 3.

PythonQt

  • The PythonQt wrappers for Qt have been upgraded to Qt5. PythonQt for Qt5 still follows the package naming of Qt4, so, e.g., QWidget is still in QtGui (instead of QtWidgets) and QWebView is still in QtWebKit (instead of QtWebKitWidgets) and so on.

  • Changed methods (oldnew):

    QtCore.QDir.convertSeparators -> QtCore.QDir.toNativeSeparators
    QtCore.QRegExp.numCaptures -> QtCore.QRegExp.captureCount
    QtCore.Qt.escape -> MLAB.escapeString
    QtCore.QTextStream.writeBoolean() -> removed
    
    QtCore.QUrl has been redesigned in Qt5 and the API has changed substantially. The new class QUrlQuery offers some methods that have been removed from QUrl.

  • PythonQt has the following new modules: QtMultimedia, QtQuick, and QtQml.

  • PythonQt now supports QtCore.Slot, QtCore.Signal, QtCore.Property (compatible to PySide/PyQt), and the creation of dynamic meta objects.

  • QSound has been moved to QtMultimedia.

  • Improved __nonzero__ check in some PythonQt wrappers.

  • Added support for Python compare functions (__eq__, etc.) in QObject wrappers.

Fixes / Enhancements (MeVisLab)

DICOM related changes

  • ReleaseToolsDICOM from ReleaseToolsDICOM.h and its corresponding namespace have been moved into the project DICOMTagTools and its corresponding namespace in file mlDICOMTagTools.h. Renaming and rebuilding projects should solve all compile and linkage problems; the signature of one tool function has changed:

    • DCMTreeInfo determineDCMTreeInfo(DCMTree::Const_TreePtr dcmTree);
      has been changed to
      void determineDCMTreeInfo(DCMTree::Const_TreePtr dcmTree, DCMTreeInfo &dcmTreeInfo);
      It may be necessary to include the header file mlDICOMTreeInfo.h to compile this.

    • Tools for conversion between ML and DICOM located in MLMultiFileVolume have been moved into new projects MLMLToDicomTools and MLDicomToMLTools. If you only make use of such tool functionality then you may reduce your project dependencies only to one or both of these projects and remove MLMultiFileVolume.

    • Many functions require a DicomMessageCollector (from project DICOMCachedIO) now which collects possible issues and other messages. The former way to return a descriptive string has been removed from a large number of functions.

  • Changes on DICOM related modules:

    • New module DicomSEGSave for exporting DICOM SEG files, supporting the DICOM Segmentation IOD.

    • New module MultiFileVolumeListSEGOutput for providing details on SEG files.

    • New module MultiFileVolumeListDiagnosisOutput: A diagnosis and analysis module for MultFileVolumeList, providing for example some basic statistic and search functionality as well as validity tests.

    • New module DicomConfigurableMessageFilter: for configuring messaging and logging of modules using this.

    • DicomModifyMultiFileVolumeExport provides an option to load MultiFileVolumeCache-files now.

    • DicomTreeCompare can detect differences in value multiplicity now.

    • DicomModifyImageTagsPlugin created exception errors on files where NumberOfTags tags does not have a value.

    • DicomTreeInfo and other modules posted unnecessary errors on empty file name selections and disabled update modes when files still do not exist.

    • DicomModifyTagsPlugin module does not accept private element tag IDs with lower 8 bits < 0x10.

    • DicomMultiFileVolumeListExport did not export pixel data any more if no ImageTagsPlugin loaded them explicitly.

    • MultiFileVolumeList*Output modules had an unbounded volume index and/or displayed volumes out of range.

    • Dicom*Save modules have an 'updateDone' trigger output now.

    • FileListFilterPlugin has support for tag search in MF volumes as well as multi-value tag search support now.

    • DicomSCSave doesn't save some tags anymore that are disallowed by the standard.

    • DirectDicomImport:

      • Added some documentation about supported DICOM import functionality.

      • Improved performance of loading .nii files.

      • Fixed that Deformable Registration Object cannot be loaded.

      • Fixed problems with non-bitmask / fractional SEG files.

      • Fixed that same sized high dimensional (>4) NM DICOMs were sorted together to a broken image .

      • Fixed problems with separation of multi-segment SEG files.

      • Fixed that unknown standard tags were shown as unknown private tags.

      • Many optimizations in the import process have been implemented, especially on enhanced multi-frame files and large series. 2D pixel data is mostly loaded on demand now, which can speed up import times.

        [Caution]Caution

        Errors and messages related to pixel data accesses in DICOM data do not appear during import time any more but much later when data is accessed.

      • When importing data via ImageLoad, DCMTK issues were not caught in the DirectDicomImport log stream but logged in the console.

      • The panel has been modernized, many elements have been moved into specific dialogs which can be opened with buttons or with double click on a volume in the volume list, all elements and fields still exist; some buttons have been realized as more compact enumerator fields.

      • Fixed that "Position Reference Indicator" tag was removed when importing Enhanced MF DICOM files.

      • DirectDicomImport and related MultiFileVolumeList*Output modules produced too many/much error output for a single error message.

      • DirectDicomImport and itkImageFileReader handle handle Sign Extensions of pixel data as well as shifting now.

      • Can read Parametric Maps now.

      • Fixed that decomposing of enhanced multi-frame files did not maintain the structure of Functional Group sequences.

      • Fixed that writing relative paths did not work for enhanced DICOM images.

      • DirectDicomImport and other modules with bit-overlay outputs used SET instead of OR for overlay merges.

      • RWV (Real World Mapping Storage) data should not be handled as image data any more.

      • Fixed error on valid import of Enhanced DICOM files with private tags in Functional Group macro sequences.

      • Fixed crashes while importing corrupted XA data.

    • MultiFileVolumeListSROutput:

      • Handles retired SR data more strictly now. The module has been revised to provide permission flags which still allow retired structures.

        [Caution]Caution

        The module is not backward compatible any more, check functionality and reconfigure modules if they are stored in networks.

    • DicomREGSave:

      • Handling mismatch of MeVisLab Worldmatrix and DICOM world tags (ImagePositionPatient, etc.). Source can be selected now.

      • DicomREGSave and DicomSEGSave add tags of Common Instance Reference Module now.

    • MultiFileVolumeListDraftView:

      • Also supports other frame types than DICOM as well as enhanced multi-frame frames.

      • The robustness against frames without Image information was improved.

  • Other DICOM related fixes and changes:

    • Some functionality has been moved to new or other existing libraries.

    • The new Value Representation UR is handled in many places now.

    • Many input fields (for example in DicomREGSave) check values with VR CS for standard compliance now, invalid strings will not be saved any more.

      [Caution]Caution

      If your application stored invalid strings before, this will not work any more. This changes the behavior especially of Dicom*Save modules.

  • Known issues:

    • Currently DirectDicomImport cannot distinguish between DICOM images with RGBA value representation - as for example stored by ImageSave - (which do not obey the DICOM standard) and valid ones only having RGB photometric representation; therefore such images are shown incorrectly.

    • DirectDicomImport is missing support for "Philips3D" files.

ITK

  • Fixed a few misbehaving module operations.

  • Minor changes and cleanups, scripts ported to Python.

VTK

  • Changes:

    • Updated VTK to version 7.1, of 2016-05-03.

    • Renamed conversion module module MLBaseToVTKPoints to the more correct name MLBaseToVTKPolyData.

    • Dropped deprecation support for versions before MeVisLab 2.3.

    • Script components in generated module wrappers use Python instead of JavaScript now.

    • New isFilePath MDL feature is used for file names and paths. This may require a confirmation of values in file and path fields when updating networks with stored paths.

    • Removed a number of wrappers for deprecated VTK classes and of many others which do not make sense as wrapped modules. Also some deprecated and useless modules and fields have been removed

  • Caveats:

    • In some situations MeVisLab redraw events get lost when rendering objects in VTK renderers. This can lead to missing redraws of the MeVisLab GUI. Dragging at application borders can resize and redraw MeVisLab in such cases.

    • Some classes wrapped as VTK modules are still unstable or have missing example networks.

    • Many connectors and fields have changed. Usually they will automatically be reconnected to new connectors, however this is not always possible. Thus stored networks may be affected or become incompatible.

      • If stored field names could not be restored, in most cases (re-)saving the network removes the warnings.

      • If connections cannot be restored, carefully check which one is missing. In most cases they can be re-established manually.

Point Cloud Library

  • New module PCLStatisticalOutlierRemoval which uses point neighborhood statistics to filter outlier data.

  • New module PCLRadiusOutlierRemoval which filters points in a cloud based on the number of neighbors they have.

  • New module PCL83xLoader: Experimental loader for IMAGINEX Azimuth DELTA Sonar .837/.83B file pairs.

  • PCLBaseObjectWrapper has a another setPointMemberXYZIntensityReplacement function which allows to set a larger point set at once from NumPy arrays.

New third-party libraries in FMEWork/ThirdParty
