Follow-up Comment #6, bug #49756 (project octave):
After trying the crashing example again, I can see something wrong on linux
too: even though this doesn't lead to a crash, the clipping of the image is
wrong when I pan/drag the image.
FTR, the problematic example is:
close all
im=uint8(rand(495,495)*255);
imx0 = 60;
imy0 = 70;
imxf = 442;
imyf = 452;
imxF = 9;
imyF = 3000;
imshow(im,'xdata',([1,size(im,1)]-imx0)*imxF/(imxf-imx0),'ydata',([size(im,2),1]-imy0)*imyF/(imyf-imy0))
axis('on','xy','normal')
The origin of the issue is that the opengl renderer assumes ydata(1) >
ydata(2) and it is a wrong assumption in this example.
I don't know if ML allows ydata(1) < ydata(2) but I'd be tempted to disallow
that or silently invert those data. Thoughts?
