Android Question

Draw smoothly scaled bitmaps on Canvas

This is how I draw

Bitmap
on
Canvas
in my Android app:

canvas.save();
canvas.scale(scale, scale, x, y);
canvas.drawBitmap(bitmap, x, y, null);
canvas.restore();


However the
Bitmap
is not scaled smoothly, no anti-aliasing is performed. How can I enable anti-aliasing?

Answer

Try this:

Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);

canvas.drawBitmap(bitmap, x, y, paint);
