GLBLENDCOLOR(3G)GLBLENDCOLOR(3G)NAME
glBlendColor - set the blend color
C SPECIFICATION
void glBlendColor( GLclampf red,
GLclampf green,
GLclampf blue,
GLclampf alpha )
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
SEE ALSO glBlendEquation(3G), glBlendFunc(3G), glGetString(3G)GLBLENDCOLOR(3G)
