GrFindColor ()

Purpose: Calculate the pixel value to use to display the specified color value. The

color value is specified as a GR_COLOR, which is a 32-bit true color
value stored as RGBX. The pixel value size depends on the architecture.

Syntax:

void GrFindColor (GR_COLOR c,

GR_PIXELVAL *retpixel);

Parameters: c

Color value to find

retpixel Pointer to the returned pixel value

GrGetSysColor ()

Purpose: Get the colors in the server color lookup table.

Syntax:

GR_COLOR GrGetSysColor (int index);

Parameter: index Index into the server color lookup table

Return: Color found at the specified index
