I’m trying to create a bitmap from a specific area on the screen. For example in the following image how could I capture the windowed area below and convert it into a bitmap?
I know you can use setDrawingCacheEnabled(true), but that captures the whole view, when all I want is an area within the view.
You can actually use Android’s
BitmapRegionDecoder.decodeRegion() after you create an
InputStream from your
You can pass a
Rect object to the
decodeRegion method like so:
BitmapRegionDecoder brd = BitmapRegionDecoder.newInstance(inputStream, true); Bitmap croppedBitmap = brd.decodeRegion(new Rect(left, top, right, bottom), null);
