Summary: texture format conversion error,
LUMINANCE/INTENSITY/LUMINANCE_ALPHA
Product: Mesa
Version: CVS
Platform: All
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
CC: [EMAIL PROTECTED], [EMAIL PROTECTED]
Env: Mesa, master cset:cd6660475646defb6311491028dfe50202709b59
After specifying a image to a texture(by glTexImage*D() with internalformat
"LUMINANCE/INTENSITY/LUMINANCE_ALPHA"), glGetTexImage() cannot get the right
RGBA values, which doesn't comply with OpenGL spec21 (chapter 6.1.4, table
6.1). While the mesa implemetation seems abidying to table 3.20 (chapter
3.8.13), which indates the derived method from those base internal format for
the texture function's calculation.
