    .SH "PARAMETERS"

        .PP target

                    Target for color clamping. target must be GL_CLAMP_READ_COLOR.

            .SH "DESCRIPTION"
                .PP 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.

            .SH "ERRORS"
                .PP GL_INVALID_ENUM is generated if target is not GL_CLAMP_READ_COLOR.
                .PP GL_INVALID_ENUM is generated if clamp is not GL_TRUE or GL_FALSE.

            .SH "ASSOCIATED GETS"
                .PP glGet() with argument GL_CLAMP_READ_COLOR.
