Android: Canvas drawBitmap?
I have a 200x200px bitmap. I want to draw the 50x50px top left corner of my bitmap, on my canvas, at coordinates 100 100 with a width and height of 50 pixels using:
drawBitmap(Bitmap bitmap, Rect src, Rect dst, Paint paint)
Here's what I've tried:
drawBitmap(myBitmap, new Rect(0,0,50,50), new Rect(100,100,150,150) , null);
What am I doing wrong?
From developer.android.com:
Parameters
-
bitmap The bitmap to draw
-
src May be null. Subset of the bitmap to draw
-
dst The rectangle that the bitmap will be scaled / translated according to
-
paint May be empty. The paint used to paint the bitmap
What's missing in my code? Thank!

You need to change the rectangles. This is because, as described in the documentation, the first rectangle is a subset of the bitmap you want to draw, the second is scaling / translation, so basically the size of the drawing destination is (50x50)
So it should look like this:
drawBitmap(myBitmap, new Rect(100,100,150,150), new Rect(0,0,50,50) , null);
