Detailed Description

Wrapper for Windows' RBGQUAD type.

TRgbQuad is a support class derived from the structure tagRGBQUAD, which is defined as follows:

typedef struct tagRGBQUAD {
   uint8  rgbBlue;
   uint8  rgbGreen;
   uint8  rgbRed;
   uint8  rgbReserved;
} RGBQUAD;

The elements rgbBlue, rgbGreen, and rgbRed specify the relative blue, green, and red intensities of a color. rgbReserved is not used and must be set to 0.

TRgbQuad is used in conjunction with the classes TPalette and TColor to simplify RGBQUAD-based color operations. Constructors are provided to create TRgbQuad objects from explicit RGB values, from TColor objects, or from other TRgbQuad objects.
