6 glBlendColor - set the blend color
7
9 void glBlendColor(GLfloat red, GLfloat green, GLfloat blue,
10 GLfloat alpha);
11
13 red, green, blue, alpha
14 specify the components of GL_BLEND_COLOR
15
17 The GL_BLEND_COLOR may be used to calculate the source and destination
18 blending factors. The color components are clamped to the range 0 1
19 before being stored. See glBlendFunc() for a complete description of
20 the blending operations. Initially the GL_BLEND_COLOR is set to (0, 0,
21 0, 0).
22
24 The type of the red, green, blue, and alpha parameters was changed from
25 GLclampf to GLfloat. This change is transparent to user code and is
26 described in detail on the removedTypes() page.
