Android - Draw bitmap as one color

Question

I have several bitmaps (game sprites) which I'd like to draw into another bitmap, however each non-transparent pixel of the source bitmap should be drawn using a single color, ignoring the original pixel color of the source. Basically, I'm trying to use the sprite as a "stamp" of a single color to be drawn into the destination bitmap.

I believe I should be using canvas.drawBitmap (Bitmap bitmap, Matrix matrix, Paint paint), however I'm not exactly sure how I should initialize the paint object. Is this approach correct?

Answer 1

You don't need to perform as many steps as Romain Guy suggests, just initialize your paint with the desired color, and use Paint.setColorFilter() with PorterDuff.Mode.SRC_ATOP

myPaint.setColorFilter(new PorterDuffColorFilter(myColor, PorterDuff.Mode.SRC_ATOP));
