[Advanced-java] png image

[Andri Yadi]

Sorry for newbie question,
I want to transmit images that are captured by camera to midp enabled
device via intenet. Because MIDP-enabled device can only
display png image, I must convert captured image to png format. I have
compressed the png image and file size is still big enough to transmit via
internet in short interval (I want to transmit frame by frame, so that
it is like video). I have reduced image's bit depth from 24 to
16, but still have big file size (about 20 Kb). If I use jpeg format, I'm
sure I can get 2 or 4 Kb of file size.

Any idea how to reduce png file size ?
Any idea will be appreciated.

Sorry for bad english ... coz I'm not englishman.
