performance - Loading only part of a bitmap file in Android

Question

I would like to load a cropped version of a bitmap image into a Bitmap object, without loading the original bitmap as well.

Is this at all possible without writing custom loading routines to handle the raw data?

Thanks, Sandor

It's actually very straightforward to do. Use

Bitmap yourBitmap = Bitmap.createBitmap(sourceBitmap, x to start from, y to start from, width, height)

Update: use BitmapRegionDecoder
