However, since binary to base64 conversion turns 3 bytes into 4 characters, it's possible to make a specific 1-line method converting an triplet of bytes ( RGB values ) into base64. But binary to ISO is easier and probably faster. Beside, although you work in 24bits, you often use a limited set of colors therefore the conversion is often not necessary or can be done using a look up table / hash table. Another significant perfomance boost is to use 256 colors or less and generate a BMP8. This way the number of bytes to convert is divided by 3, and if you use even less colors, you can position them in the range of characters that don't change when converted to ISO hence eliminating the conversion altogether ;) [url=http://www.p01.org/][sigrotate][img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_love.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_love_small.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_charly.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_dk.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_reason.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_galaxy.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_neon88x31.gif[/img]\|[img]http://poi.ribbon.free.fr/files/p01_ozoneasylum_sig_teapot.png[/img][/sigrotate][/url] Loading...
