Detailed Description

SoView2D is a 2D viewer for image data.

Author

Florian Link

It is integrated into OpenInventor and provides

event handling and drawing on slices by the use of the SoView2DExtension classes. For a detailed description of its usage, see the html documentation in MeVisLab.

protected

bool SoView2D::cineAdvanceZ ( bool  backwards, bool  wrapAround  )

protected

these methods advance the slice/timepoint in cine mode.

If backwards is set, they move backwards. If wrapAround is set, the slice/timepoint is set to the first/last value if the end is reached, otherwise the slice/timepoint is not changed, but in both cases true is returned (i.e. for wrap-around or stop)

void SoView2D::cineDirectionChanged ( )

If sliceID is set to NO_SLICE_ID, it will be set to the index of the slice that was hit by this test. If sliceID is any other value, it is taken to be the index of a slice and the test is only performed on this slice. This is used to grab the mouse for this slice at a mouse press.
