Apps Image Manipulation

[otb82]

Hi,
I would like to save on the disk the result of the merge of 2 pictures:
- a wallpaper
- a transparent png on the top

I have no idea where to start my search.
Thanks for your help.

You simply say:

Canvas canvas = new Canvas();
Bitmap result_image = Bitmap.createBitmap( width, height, Config.ARGB_8888 );
canvas.setBitmap( result_image );

then you can draw on canvas ( for drawing a bitmap use drawBitmap method ). When done you can see the result in result_image.

Hope that helps
