title: Save Canvas Drawing on Image in Android
body: <p>I'm working on an application in which I'v a custom ImageView. Using custom imageview I can drag,zoom, and paste text over over it (using its onDraw() function). Now at the end I want to put all the canvas drawing over image and want to save it in the file system. I have tried imageView.getDrawingCache() method but it does not fulfill my requirements as when I zoom out the it captures black sides of the image too. Any suggestions?</p>
