.SH "C SPECIFICATION"

\fBGL_BLEND_COLOR\fR
.RE
.SH "DESCRIPTION"
.PP
The
\fBGL_BLEND_COLOR\fR
may be used to calculate the source and destination blending factors\&. The color components are clamped to the range
0 1
before being stored\&. See
\fBglBlendFunc\fR()
for a complete description of the blending operations\&. Initially the
\fBGL_BLEND_COLOR\fR
is set to (0, 0, 0, 0)\&.
.SH "NOTES"
.PP
The type of the
\fIred\fR,
\fIgreen\fR,
\fIblue\fR, and
\fIalpha\fR
parameters was changed from GLclampf to GLfloat\&. This change is transparent to user code and is described in detail on the
\fBremovedTypes\fR()
page\&.
