[REBOL] Re: explanation, gurus? :-) (image memory representation)

From: robbo1mark:aol at: 21-Aug-2001 5:05

PEKR, The image! data is contained in a binary! string in which each group of two characters is a value corresponding to a hex value equivalent to one byte. ie {FFFFFF} = FF FF FF (hex) or 255.255.255 each RGB tuple can be contained in 6 hex chars which is equivalent to total range of colour values 0 thru 255 for each Red Green & Blue. First, Second, Third, Fourth, Last etc take subsequent groups of 6 chars as described above. Hope that helps, Mark Dickson In a message dated Mon, 20 Aug 2001 6:27:07 PM Eastern Daylight Time, "Petr Krenzelok" <[petr--krenzelok--trz--cz]> writes:
