From 143959dba65c78f404a5d8984edb5ec5e507325e Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Thu, 22 Jun 2017 12:20:58 -0700 Subject: Move image_diff code into testing/image_diff/ It is not actually a sample program to demonstrate how to use PDFium APIs. It is more of a test utility program. Remove header include dependency from samples/ to core/, to set a good example.
