How to save a picture in RMS?

[genepi-]

Hi,

My application needs to save a picture taken with the camera into the RMS for future use. How can I efficiently store/encode the picture, preferably without using non-standard API?

Presently, I use MIDP-2 Image.getRGB() to access the picture bits and then drop alpha channel and "useless" bits, but the data is still tens of KB...

Any idea?

you may compress it... into png for example

Great idea, but how do you do that with standard MIDP?
Is there a *small* PNG encoder/decoder? Well, the decoder is not really necessary as the Image constructor can recreate it from the PNG bytes...

Nope, AFAIK.
Just go to google, search "png source code" and Java C C++ by your choice When I did such search ~6 months ago, I found pretty much. Just get and use ))

Adding a custom PNG encoder, with the CRC32 and zip code, is going to turn my application extra-fat :-(

How couldn't they include it in the MIDP API???
