From 8124f0bc1893e0997989913044665fa1c5cf79d7 Mon Sep 17 00:00:00 2001 From: Szabolcs David Date: Thu, 25 Oct 2018 16:36:12 +0200 Subject: Move printing operation to a new thread MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Printing operations were blocking the UI thread, so applications were irresponsive when printing in large size or high resolution. Introduce a new worker for the painting logic and use shared pointers to carry the data around and avoid copying PDF data between threads.
