Using OTB_USE_GL_ACCEL streches images in scroll widget

Mantis Issue 70, reported by jmichel, assigned to jmichel, created: 2009-01-09

See attached snapshots for illustration.

1231515170 - julienThe square where the texture is drawn has a size depending on the input image geometry.

1231731015 - christopNo difference any more between scroll, zoom and full resolution windows. => seg fault when resizing zoom in viewer manager.

1231750383 - julienThe hDisplayed() and wDisplayed() methods were redefined too low in the class hierarchy. Therefore when using the otb::FixedSizeFullImageWidget alone, the default implementation was called, leading to the stretching phenomena.

This has been fixed in revision : http://hg.orfeo-toolbox.org/OTB/rev/ae28398a39cb

1231811853 - christopStill have some problem with the zoom window. It might not be related to this fix and had been there before, but as the solution rely in the hDisplayed() and wDisplayed() methods I suspect, I don't open a new bug.

Open the viewer manager Open qb_RoadExtract.tif Show Resize the zoom window to be bigger that the full resolution either in x or y (or both). Click on the scroll
