--- Comment #44 from Iago Toral <ito...@igalia.com> --- (In reply to Iago Toral from comment #43) (...) > 3) Luminance formats have special requirements. A conversion to Luminance > from RGBA requires to do L=R+G+B for example. This is something that > _mesa_format_convert cannot achieve at the moment, because neither > pack/unpack functions nor _mesa_swizzle_and_convert do this kind of > operation, so I wonder what is the right thing to do here.

The current code > does another pass specifically for this, right before packing to the dst. And likewise, a conversion to RGBA from Luminance requires to do R=L,G=0,B=0,A=1, but unpack functions and _mesa_swizzle_and_convert will do R=L,G=L,B=L,A=1, so again we need another pass to correct this to the expected result. -- You are receiving this mail because: You are the QA Contact for the bug.
