#ifndef MACOSXCOLOR_H
#define MACOSXCOLOR_H
/*
* The generic Tk code uses the X11 GC type to describe a graphics context.
* (A GC is a pointer to a struct XGCValues). The foreground and background
* colors in a GC are unsigned longs. These are meant to be used as indexes
* into a table of XColors, where an XColor is declared in Xlib.h as:
* typedef struct {
* unsigned long pixel;
* unsigned short red, green, blue;
* char flags;
* char pad;
* } XColor;
*
* The xlib function XParseColor creates XColors from strings. It recognizes
* literal hexadecimal color specifications such as "#RRGGBB" as well as the
* standard X11 color names. When XParseColor creates an XColor it fills in
* all of the fields except for the pixel field, and then passes the XColor
* to TkpGetPixel to get a value to use for the pixel field. Since TkpGetPixel
* is platform specific, each platform is free to choose a value which can
* be used to set the foreground or background color in the platform's graphics
* context.
*
* Tk represents a color by a struct TkColor, which extends the XColor struct.
* Tk provides a mapping from color names to TkColors which extends the mapping
* provided by XParseColor but also allows for platform specific color names.
* By convention, these platform specific color names begin with the string
* "system". The mapping from names to TkColors is implemented by the function
* TkpGetColor defined for the Macintosh in this file. The pixel field in the
* XColor contained in a TkColor will be stored in the X11 graphics context.
* In X11 the pixel field is used as an index into a colormap. On the Mac
* the high order byte of the pixel is used to indicate a color type and
* the low 24 bits are either used as an rgb value (if the type is rgbColor)
* or as an index into a table of color descriptions.
