6 glColorTableParameter - set color lookup table parameters

9 void glColorTableParameterfv(GLenum target, GLenum pname,
10 const GLfloat * params);
11
12 void glColorTableParameteriv(GLenum target, GLenum pname,
13 const GLint * params);
14
16 target
17 The target color table. Must be GL_COLOR_TABLE,
18 GL_POST_CONVOLUTION_COLOR_TABLE, or
19 GL_POST_COLOR_MATRIX_COLOR_TABLE.
20
21 pname
22 The symbolic name of a texture color lookup table parameter. Must
23 be one of GL_COLOR_TABLE_SCALE or GL_COLOR_TABLE_BIAS.
24
25 params
26 A pointer to an array where the values of the parameters are
27 stored.
28
30 glColorTableParameter is used to specify the scale factors and bias
31 terms applied to color components when they are loaded into a color
32 table. target indicates which color table the scale and bias terms
33 apply to; it must be set to GL_COLOR_TABLE,
34 GL_POST_CONVOLUTION_COLOR_TABLE, or GL_POST_COLOR_MATRIX_COLOR_TABLE.
35
36 pname must be GL_COLOR_TABLE_SCALE to set the scale factors. In this
37 case, params points to an array of four values, which are the scale
38 factors for red, green, blue, and alpha, in that order.
39
40 pname must be GL_COLOR_TABLE_BIAS to set the bias terms. In this case,
41 params points to an array of four values, which are the bias terms for
42 red, green, blue, and alpha, in that order.
43
44 The color tables themselves are specified by calling glColorTable().
45
47 glColorTableParameter is available only if ARB_imaging is returned from
48 calling glGetString() with an argument of GL_EXTENSIONS.
49
51 GL_INVALID_ENUM is generated if target or pname is not an acceptable
52 value.
53
54 GL_INVALID_OPERATION is generated if glColorTableParameter is executed
55 between the execution of glBegin() and the corresponding execution of
56 glEnd().
