The mapping is as follows: -.P -.TS -center; -lb cb cb cb cb cb cb -l c c c c c c. -_ -Internal Format Red Green Blue Alpha Luminance Intensity -_ -_const(ALPHA) A -_const(LUMINANCE) R -_const(LUMINANCE_ALPHA) A R -_const(INTENSITY) R -_const(RGB) R G B -_const(RGBA) R G B A -_ -.TE -.P -Finally, the red, green, blue, alpha, luminance, and/or intensity components of -the resulting pixels are stored in the color table. -They form a one-dimensional table with indices in the range -[0,\ __width\ \-\ 1]. -.P -If __target is _const(PROXY_*), -_cmnd recomputes and stores the values of the proxy color table's state -variables -_const(COLOR_TABLE_FORMAT), -_const(COLOR_TABLE_WIDTH), -_const(COLOR_TABLE_RED_SIZE), -_const(COLOR_TABLE_GREEN_SIZE), -_const(COLOR_TABLE_BLUE_SIZE), -_const(COLOR_TABLE_ALPHA_SIZE), -_const(COLOR_TABLE_LUMINANCE_SIZE), and -_const(COLOR_TABLE_INTENSITY_SIZE). -There is no effect on the image or state of any actual color table. -If the specified color table is too large to be supported, then all the -proxy state variables listed above are set to zero. -Otherwise, the color table could be supported by _cmnd -using the corresponding non-proxy target, -and the proxy state variables are set as if that target were being defined. -.P -The proxy state variables can be retrieved by calling -_cmnd(GetColorTableParameter) with a target of -_const(PROXY_*). -This allows the application to decide if a particular _cmnd -command would succeed, and to determine what the resulting color table -attributes would be. -.P -If a color table is enabled, and its width is non-zero, then its -contents are used to replace a subset of the components of each RGBA -pixel group, based on the internal format of the table. -.P -Each pixel group has color components (R, G, B, A) -that are in the range [0.0,\ 1.0]. -The color components are rescaled to -the size of the color lookup table to form an index. -Then a subset of the components based on the internal format of the table are -replaced by the table entry selected by that index. -If the color components and contents of the table are represented as follows: -.P -.TS -center; -cb cb -c l. -_ -Representation Meaning -_ -\f7r\fP Table index computed from \f7R\fP -\f7g\fP Table index computed from \f7G\fP -\f7b\fP Table index computed from \f7B\fP -\f7a\fP Table index computed from \f7A\fP -\f7L[i]\fP Luminance value at table index \f7i\fP -\f7I[i]\fP Intensity value at table index \f7i\fP -\f7R[i]\fP Red value at table index \f7i\fP -\f7G[i]\fP Green value at table index \f7i\fP -\f7B[i]\fP Blue value at table index \f7i\fP -\f7A[i]\fP Alpha value at table index \f7i\fP -_ -.TE -.P -then the result of color table lookup is as follows: -.P -.ne 10 -.TS -center; -l l s s s -l l l l l -l l l l l. -_ - Resulting Texture Components -Table Internal Format R G B A -_ -_const(ALPHA) R G B A[a] -_const(LUMINANCE) L[r] L[g] L[b] At -_const(LUMINANCE_ALPHA) L[r] L[g] L[b] A[a] -_const(INTENSITY) I[r] I[g] I[b] I[a] -_const(RGB) R[r] G[g] B[b] A -_const(RGBA) R[r] G[g] B[b] A[a] -_ -.TE -.P -When _const(COLOR_TABLE) is enabled, the colors resulting from -the pixel map operation (if it is enabled) are mapped -by the color lookup table before being passed to the convolution -operation.
