------- Comment #1 from [EMAIL PROTECTED] 2007-03-09 07:39 PST ------- Table 6.1 only applies to glGet[Compressed]TexImage(), not texturing in general. (when texturing, a luminance texture is supposed to appear as gray-scale so R=G=B=L.) For glGetTexImage(), we'll typically use the FetchTexel() functions. Luminance will be converted to R=G=B. But in the _mesa_pack_rgba_span_float() function we'll convert RGB back to L. I think we have a problem there, though. _mesa_pack_rgba_span_float() is used for both glReadPixels() and glGetTexImage(). For the former the conversion is L=R+G+B but for the later we want L=R (or =G or =B). Looks like we need an extra parameter/flat to indicate how RGB should be converted to L. I'll look into that... -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- Take Surveys.
