I must be missing something... > I did not look in detail into your code but just in case you don't know, here are a few hints: - Palm use RGB565 for it's 16 bit color. Most JPEG library convert to 24 bits RGB. If this is your case, tou must convert your data from 24 bits RGB to RGB565. It is done by masking and shifting. 5bits for R, 6 bits for G and 5 bits for B. The library I am using (jcpalm) can convert directly to RGB565. It is avaliable from the eyemodule web site in the developer section. www.eyemodule.com It can be used freely as long as you acknowledge the copyright inside your own copyright. It is the case for all library made from the code from the IJG (Independant JPEG Group). See the readme.txt with the library. (By the way, if you open the about box of MSN Messenger, you will see the same acknoledgment of the IJG) Hope this helps -- Regis St-Gelais www.laubrass.com -- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
