Saving canvas to bitmap on Android

Question

I\'m having some difficulty with regards to placing the contents of a Canvas into a Bitmap. When I attempt to do this, the file gets written with a file size of around 5.80K

Answer 1

You'll have to draw after setting the bitmap to the canvas. Also use a new Canvas object like this:

Canvas canvas = new Canvas(toDisk);
canvas.drawPath(currentPath, pen);
toDisk.compress(Bitmap.CompressFormat.PNG, 100, new FileOutputStream(new File("arun.png")));

I recommend using PNG for saving images of paths.
