Hello everybody,
I have written an applet that allows drawing images (with the help of the Graphics class). My data is stored in a byte array.

How can I save these images on the phone?

Any idea? package?...
Thanks a lot for your help,

Rikow

Hi rikow,
You can save the images to the filesystem on the phone if ur phone supports jsr75.Please read jsr75 guidelines.

Thanks

Thanks a lot for your answers!
but....
Do I need a PNG encoder (for example) for midlet? I did not found any on the web...
My phone is a Nokia 6680 and supports FileConnection... but I think the main problem is to encode my image (byteArray) in a picture format, as PNG.
How can I do that?
Any Idea? link? code? encoder?

Hi,

U will surely require a png encoder. this is because u have to convert an image to bytearray inorder to save it in the filesystem.

AFAIK there is no readily available png encoders for J2me. the only thing u can do is that there are png encoders available for j2se. u have to port it into j2me.

For this u may use google

Wang

hello Wang,

bear with me (still learning) but PNG encoding should be default encoding for captured image byte array (PNG is default encoding that should be implemented to byte array according to JSR docs),
also we (I also have 6680) should be able to specify encoding in getSnapshot(..) method,
according to Nokia docs that's default in fact:

videoControl.getSnapshot(null);     // default PNG, 160x120

(taken from "Java Developer library" doc),
so after taking byte array shouldn't we simply be able to write it to file with ".png" extension?

regards,
Peter

I think what he meant was images drawn, not captured by the camera..
Anyway, does anyone of you know of a j2me jpg encoder? thanks!

May be you should give a try with the encoding part of "JpegEncoder.java" in this link (Not tried it myself yet!)
http://koders.com/java/fidD639747F90...essdash.ui.lib
Yep! This is a J2SE code, give a try adapting the encoding part to J2ME!

Hope this helps!

Regards
Gopal
