I'm trying to make an android game using sprites, (or very pixelated characters, backgrounds etc.). I draw them on the canvas like so...

matrix.preScale(xrat,yrat);

canvas.drawBitmap(img, matrix, null);

Where img is the Bitmap and the xrat and yrat are the scales.

My problem is that when I test, the Bitmap is blurry or anti-aliased, is there a way to prevent this? The rigid-blocky art style of the game will be ruined if the blocks are blurry.

Any (ANY) help appreciated!
