From eb5ef3312260479ada82e6463e7ec3a8b6245e7f Mon Sep 17 00:00:00 2001 From: Allan Sandfeld Jensen Date: Thu, 7 Aug 2014 13:47:21 +0200 Subject: Handle 10-bit per color formats in qt_mac_toCGImage Add support for the four new RGB30 formats to qt_mac_toCGImage so that they get converted to ARGB32_Premultiplied instead of potentially misinterpreted.
