Collaboration diagram for gml_TColor_HLS_FFF:

Detailed Description

A union type used to represent HLS-encoded color pixels. HLS is Metrick's Hue, Lightness, Saturation colorspace.

Some of this code is adapted from section 15.3.5 of "Computer Graphics: Principles and Practice", by J.D. Foley and A. van Dam.


Public Member Functions
	gml_TColor_HLS_FFF (UInt8 const r, UInt8 const g, UInt8 const b)
	Convert a 24-bit RGB triplet into HLS and fill in the object.
	gml_TColor_HLS_FFF (const void *const ptr)
	Fill the structure from data in memory.
	gml_TColor_HLS_FFF ()
	Leave the structure `as is'. I.e. probably zero.
void	Print ()
	Dump a representation of the pixel to stdout: channels in hex and in degrees, percent, percent format.
void	Store (void *const ptr)
	Place the structure's data in memory.
void	Convert (UInt8 &r, UInt8 &g, UInt8 &b)
	Convert the HLS data in this object to a 24 bit RGB triplet.
UInt16	Distance (const gml_TColor_HLS_FFF other)
	Compute the 16-bit distance to another HLS pixel. The euclidian distance in the hue, saturation disc is used.
