From 7b5e5536a18123f568afca99dc8f89019eab2c77 Mon Sep 17 00:00:00 2001 From: scroggo Date: Thu, 4 Feb 2016 06:14:24 -0800 Subject: Add SkAndroidCodec::getPixels This is a synonym for the version of getAndroidPixels that accepts only three parameters (i.e. no AndroidOptions). It is very similar to SkCodec::getPixels, so I think the motivation for naming the version with options differently does not apply here. Add comments to the header describing defaults. Update the test to use a template, and delete a lot of redundant code. Rename a variable to stop shadowing another variable.
