Hi, I am writing a custom view and for optimization purposes, I draw some static part of the view in a Bitmap. Unfortunately, the quality of the rendering when using an offscreen bitmap is noticeably less compared to rendering into the view's canvas bitmap. Here are two screenshots showing the difference
Rendering into view's Canvas: <https://lh5.googleusercontent.com/-wSjtLmhUgz8/UQZV96LTo6I/AAAAAAAAAEM/r9saff_8dlM/s1600/01_view_canvas.png> Rendering into a Bitmap Canvas <https://lh3.googleusercontent.com/-jVuFcXhAf7g/UQZWK7NBNfI/AAAAAAAAAEU/0AfCGfQMudU/s1600/02_bitmap_canvas.png> The difference is most noticeable at the horizontal black line. The anti-aliasing algorithm seems to affect more pixels (is wider). The drawing code is the same in both cases, and the offscreen canvas is created like this final Bitmap tempBitmap = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); final Canvas tempCanvas = new Canvas(tempBitmap); Any ideas on how to get the same rendering in the offscreen canvas as in the view's ?
