hi, guys

I try to draw a picture by canvas. I found API demo has two ways to draw a picture.

1.http://code.google.com/android/samples/ApiDemos/src/com/google/android/samples/graphics/BitmapDecode.html

2.mBitmap = BitmapFactory.decodeResource(context.getResources(),R.drawable.balloons);
canvas.drawBitmap(mBitmap, x, y, paint);

By those ways, the pictures showed on the emulator are different size.

How to change the size of the picture as I like?

opts.inJustDecodeBounds = false; // this will request the bm
opts.inSampleSize = 10; // scaled down by 10
