From 3d0cd1d0360ab3e536be87798415fef60222aac4 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Fri, 13 Apr 2018 13:41:58 -0700 Subject: Expose PngHandler via resources.h. As a private header for testing purpose. PngHandler additionally loads a given filename if the one with '/res/images' prefix is not available. It also provides color_type/bit_depth that are parsed from the PNG file. This allows reusing the same code for the ResourcesTest (renamed from ResourceTest). Test: Run recovery_manual_test on marlin.
