[Insight-users] Problem linking InsightApplications libITKFltkImageViewer.so

[Chris Turner]

So I'm currently trying to extract the logic of Curves2DExtractor to
free it from its fltk dependency. Basically what I did was to remove
all fltk reverences and especially the SpatialFunctionControl
variable. Which is only used for visualization right?

But my problem is now that when I load a DSA JPEG picture the filter
makes all the white regions red. Which is definitely not what it
suppose to do. But I didn't changed much beside of removing the
SpatialFunctionControl.  If it helps I could post my code...


Btw still trying to compile the original code. Used several fltk
version but nothing helped.

I appreciated any help!

Thanks
Chris
