NAME

       glClampColor - specify whether data read via glReadPixels() should be clamped

C SPECIFICATION

       void glClampColor(GLenum target, GLenum clamp);

PARAMETERS

       target
           Target for color clamping.  target must be GL_CLAMP_READ_COLOR.

       clamp
           Specifies whether to apply color clamping.  clamp must be GL_TRUE or GL_FALSE.

DESCRIPTION

       glClampColor controls color clamping that is performed during glReadPixels().  target must
       be GL_CLAMP_READ_COLOR. If clamp is GL_TRUE, read color clamping is enabled; if clamp is
       GL_FALSE, read color clamping is disabled. If clamp is GL_FIXED_ONLY, read color clamping
       is enabled only if the selected read buffer has fixed point components and disabled
       otherwise.

ERRORS

       GL_INVALID_ENUM is generated if target is not GL_CLAMP_READ_COLOR.

       GL_INVALID_ENUM is generated if clamp is not GL_TRUE or GL_FALSE.

ASSOCIATED GETS

       glGet() with argument GL_CLAMP_READ_COLOR.
