set color lookup table parameters

Deprecation Notice

Note that this function has been marked deprecated in the OpenGL 3.0 specification. You should not be using this function in new code, though it will likely be supported by most implementations via the GL_ARB_compatibility extension. For more information on OpenGL 3.x deprecations, see the deprecations page.

Signature

glColorTableParameter( )->

glColorTableParameterfv( GLenum ( target ) , GLenum ( pname ) , const GLfloat * ( params ) )-> void

glColorTableParameterfv( target , pname , params )

glColorTableParameterfv(GLenum(target), GLenum(pname), GLfloatArray(params)) -> None

glColorTableParameteriv( GLenum ( target ) , GLenum ( pname ) , const GLint * ( params ) )-> void

glColorTableParameteriv( target , pname , params )

glColorTableParameteriv(GLenum(target), GLenum(pname), GLintArray(params)) -> None

Parameters

Variables	Description
target	The target color table. Must be GL_COLOR_TABLE , GL_POST_CONVOLUTION_COLOR_TABLE , or GL_POST_COLOR_MATRIX_COLOR_TABLE .
pname	The symbolic name of a texture color lookup table parameter. Must be one of GL_COLOR_TABLE_SCALE or GL_COLOR_TABLE_BIAS .
params	A pointer to an array where the values of the parameters are stored.

Description

glColorTableParameter is used to specify the scale factors and bias terms applied to color components when they are loaded into a color table. target indicates which color table the scale and bias terms apply to; it must be set to GL_COLOR_TABLE , GL_POST_CONVOLUTION_COLOR_TABLE , or GL_POST_COLOR_MATRIX_COLOR_TABLE .

pname must be GL_COLOR_TABLE_SCALE to set the scale factors. In this case, params points to an array of four values, which are the scale factors for red, green, blue, and alpha, in that order.

pname must be GL_COLOR_TABLE_BIAS to set the bias terms. In this case, params points to an array of four values, which are the bias terms for red, green, blue, and alpha, in that order.

The color tables themselves are specified by calling glColorTable .

Notes

glColorTableParameter is available only if

ARB_imaging

is returned from calling glGetString with an argument of GL_EXTENSIONS .

Errors

GL_INVALID_ENUM is generated if target or pname is not an acceptable value.

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