gml_RGBColor.h File Reference

Detailed Description

Defines the gml_TRGBColor struct: a structure for representing color and converting from the canonical RGB representation to other representations.


Classes
struct	gml_TRGBColor
	High-resolution (48-bit) colors. More...
Defines
#define	GML_CCOLORARRAYNBELEM 50
	number of predefined colors
Functions
GML_EXTERN_C gml_TError	gml_RGBColorPixelValue (gml_TRGBColor c, gml_TPixelEncoding encoding, void value)
	Converts the color c into a pixel value according to the encoding encoding.
GML_EXTERN_C gml_TError	gml_RGBColorSetFromValue (gml_TRGBColor c, gml_TPixelEncoding encoding, void value)
	Sets the color c from the pixel value at address value.
Variables
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_DefaultArray [GML_CCOLORARRAYNBELEM]
	array of predefined colors
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_White
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_Black
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_Red
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_Green
GML_EXTERN_C gml_TRGBColor	gml_gRGBColor_Blue

GML_EXTERN_C gml_TError gml_RGBColorPixelValue	(	gml_TRGBColor *	c,
		gml_TPixelEncoding	encoding,
		void *	value
	)

Converts the color c into a pixel value according to the encoding encoding.

Stores the result at the address value. The size of what is pointed to by value varies depends on encoding:

GML_EXTERN_C gml_TError gml_RGBColorSetFromValue	(	gml_TRGBColor *	c,
		gml_TPixelEncoding	encoding,
		void *	value
	)

Sets the color c from the pixel value at address value.

Conversion is done according to the encoding of the pixel. See gml_RGBColorPixelValue() for a discussion on the size of value.
