Function Documentation

fl_parse_color()

int fl_parse_color	(	const char *	p,
		uchar &	r,
		uchar &	g,
		uchar &	b
	)

Parse a string containing a description of a color and write r, g, and b.

This call is used by the Pixmap file format interpreter and by the command line arguments parser to set UI colors.

RGB color triplets usually start with a '#' character, but it can be omitted if it does not conflict with the later rules. Color components are defined in hexadecimal notation with 1, 2, 3, or four hex digits per component, making color triplets 3, 6, 9, or 12 characters long. The interpreter is case insensitive. Valid code examples include "FF0000" for red, "#0F0" for green, and "000000004444" for a dark blue.

On the X11 platform, color values can also be given a color name like "red". The list of accepted color names is provided by the X11 server.

If none of the color interpretations work, fl_parse_color returns 0. The Pixmap reader interprets those as transparent, and are usually written as "None", "#transparent", or "bg".

Parameters

[in]	p	a C-string describing the color
[out]	r,g,b	the color components in the 0...255 range

Returns

0 if the color cannot be interpreted, 1 otherwise
