Try using a known bitmap config.
Dono if this is ok,... here it goes:
public Bitmap loadRGBA(String filename) throws Exception{
File sdDir = Enviroment.getExternalStorageDirectory(); //Base
SDCard folder
File f = new File(sdDir, filename); //relative path+filename from
SDCard
Bitmap im = BitmapFactory.decodeFile(f.getAbsolutePath());
im = im.copy(Config.ARGB_8888), false); //ARGB_8888 is more
compatible
if (im==null) throw new Exception("Error generating bitmap.");
end;
!!! Now that you have your bitmap in known formar, just use it..
Bitmap dummy = loadRGBA("myDummy.jpg");
int w = dummy.getWidth();
int h = dummy.get-height();
byte[] data = new byte[w*h*4];
Buffer buf = new ByteBuffer.wrap(data);
dummy.copyPixelsToBuffer(buf);
yourComputImge(buf);
dummy.copyPixelsFrom(buf); //Updates the bitmap
//Save it, or display it
There may be some errors in code and may have some wrong names, it all
came from my bad brain.
Hope it helps
