I am facing a weird problem.
I render a scene and then copy it into an image. When doing this myself, with my own program, everything is fine, the image is beautiful. When I do the same for a plugin for a program (here graphite), the image is drawn with big pixels, like if I copied the scene in a smaller image.
Actually I’m pretty sure that I do exactly the same thing: the image sizes are the same (512*512), the used parameters are also the same (clamp_to_edge and linear min/mag filters), and of course I render with the same viewport/projection matrix and modelview matrix.
I really don’t know where to look for.
Any hints ?
