From c573a40ed5024b463e47088d307e3164a486dba5 Mon Sep 17 00:00:00 2001 From: msarett Date: Tue, 2 Aug 2016 08:05:56 -0700 Subject: Add drawImageLattice() and drawBitmapLattice() APIs The specified image/bitmap is divided into rects, which can be draw stretched, shrunk, or at a fixed size. Will be used by Android to draw 9patch (which are acutally N-patch) images.
