I think another approach would be to temporarily set the Sampler.sRGBDecode field to GL_SKIP_DECODE_EXT, use the non-sRGB path to get the texels, then restore Sampler.sRGBDecode to its original value. Call _mesa_set_fetch_functions() as needed to choose the non-decoding texel fetch functions. Then we could avoid the linear_to_nonlinear() function altogether.
We should probably have a piglit test to exercise glGetTexImage with sRGB textures... -Brian On Sat, May 21, 2011 at 5:37 PM, Mike Kaplinskiy <mike.kaplins...@gmail.com> wrote: > Sorry looks like I edited that comment a few too many times.
