From fa05e97fc4d796bd12e21c32634d9614f8edf607 Mon Sep 17 00:00:00 2001 From: stephana Date: Mon, 2 Jan 2017 06:19:41 -0800 Subject: Gold support in PDFium Extends the PDFium tests to collect images and meta data to be uploaded to Gold. This feature is triggered by adding the --gold_* flags. It extends pdfium_test to output the MD5 hash of the underlying pixel buffer for each page it renders. That output is then processed by test_runner.py to generate the gold meta data. This behavior is modeled after the 'dm' tool in skia. See https://skia.googlesource.com/skia/+/master/dm/DM.cpp#1090 This should not cause any change in the current behavior of the tests, it will be trigger once we update the buildbot recipe.
