I’m trying to write a program that can create a GIF from an erosion animation; here:
(the build directory has some testing files)
Initially i tried to get the data from the framebuffer with glgetteximage; but this didn’t work in that i just got uninitialized memory. So i changed it to glReadPixels (line 260 of viewwidget.cpp); and now i get an invalid operation error and i don’t know why.
