How to clean up a bitmap?

Question

I'm creating a new empty transparent Bitmap and making some modifications to it.

Is there a way to clean up this (make transparent and empty again) without creating new instance of Bitmap?

UPDATE: Thanks for your help. I have found answer.

// Fills the bitmap's pixels with the specified Color. 
bitmap.eraseColor(somecolor);

Answer 1

Try this:

myBitmap.eraseColor(android.graphics.Color.TRANSPARENT);

The constant int value of TRANSPARENT is 0x00000000.
