Framebuffer access

[ganesha16hnr]

Hi,

I am developing a J2ME MIDlet which does the following things.
1. Accesses the framebuffer or graphics context using DirectGraphics: getpixels( ) method.
2. Put the extracted pixels in a .png or .bmp file
3. Change the colour of the pixels

I know how to do the 3rd step.

Please anybody provide me a code which does above actions or atleast the procedure on how to do this.
(j2me is preferably for nokia series 40 phones.)

Thanks,

You can only access pixels produced by your own MIDlet (the canvas of your app).

You have no access to the screen/framebuffer data for some other app or the system in general, using j2me.

You need to paing what you want to an Image, then paint the image to the screen, so that you can get the pixels from the image.

Also: PNG Encoding in Java ME.
