Function Documentation

a_Color_parse()

int32_t a_Color_parse	(	const char *	str,
		int32_t	default_color,
		int *	err
	)

Parse a color string.

• If the string begins with # or with 0x, return the color number (with 'RGB' expanded to 'RRGGBB').
• Else search the set of named colors.
• As a last resort, treat it as bare hex as in the first case.

Returns

• Parsed color if successful,
• default_color on error.

"err" argument:

• 0 if a color beginning with '#' is successfully parsed or the color is a recognized word.
• 1 if the color is bare hex or can't be parsed at all.
• 2 if a color beginning with 0[xX] is successfully parsed.
