From 68d28aad97894c5b1fa6875b2cb3a9baa0c8284f Mon Sep 17 00:00:00 2001 From: Dieter Verfaillie Date: Fri, 4 Nov 2011 09:44:35 +0100 Subject: [PATCH] win32: fix pasting screenshots taken with PrintScreen or Alt+PrintScreen These are found on the clipboard in the biCompression == BI_BITFIELDS && biBitCount >= 16 format. In this case the BITMAPINFOHEADER is followed by three DWORD specifying the masks of the red green and blue components, but bfOffBits was not being adjusted accordingly.
