Summary: texture 1D's border not comply with internal format
Product: Mesa
Version: CVS
Platform: Other
OS/Version: Linux (All)
Status: NEW
Severity: trivial
Priority: lowest
Component: Drivers/DRI/i915
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I wrote below code:
GLfloat bcolor [] = {0.5, 0.8, 0.6, 0.4 };
glTexParameterf(GL_TEXTURE_1D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_BORDER);
glTexParameterf(GL_TEXTURE_1D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_BORDER);
glTexImage1D(GL_TEXTURE_1D, 0, GL_LUMINANCE,
64, 0, GL_RGBA, GL_FLOAT, (unsigned char *)texBuf);
glTexParameterfv(GL_TEXTURE_1D, GL_TEXTURE_BORDER_COLOR, bcolor);
Then draw a polygon. The texture object beyone the range[0,1] will use the
border color.
With i915 driver, the texel color on border is: 0.501961 0.800000 0.600000
With xlib and i965 driver, the texel color on border is: 0.501961 0.501961
0.501961
It seems xlib and i965 driver use internal format(GL_LUMINANCE) to store border
texel, but i915 driver store the border texel separately.
