C SPECIFICATION

GLclampf green,

GLclampf blue,

GLclampf alpha )

Image /web_man_pages/man_unzipped/en/centos/5/5.61.png

PARAMETERS

red, green, blue, alpha

specify the components of GL_BLEND_COLOR

DESCRIPTION

The GL_BLEND_COLOR 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 glBlendFunc for a complete description of the blending operations. Initially the GL_BLEND_COLOR is set to (0, 0, 0, 0).

NOTES

glBlendColor is part of the GL_ARB_imaging subset. glBlendColor is present only if GL_ARB_imaging is returned when glGetString is called with GL_EXTENSIONS as its argument.

ERRORS

GL_INVALID_OPERATION is generated if glBlendColor is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

glGet with an argument of GL_BLEND_COLOR
