NAME

6       glBlendColor - set the blend color
7

C SPECIFICATION

9       void glBlendColor(GLfloat red, GLfloat green, GLfloat blue,
10                         GLfloat alpha);
11

PARAMETERS

13       red, green, blue, alpha
14           specify the components of GL_BLEND_COLOR
15

DESCRIPTION

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

NOTES

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.
