| | | | | | | | | | | | | | | | | | | | When the state of the paint changes then the one used for the picture paintengine needs to be kept in sync. Otherwise the rendering will be incorrect.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

* | Do not always fallback to bitmap printing when printing alpha.Jan Arve Saether2014-05-311-16/+24
|/ | | | | | | | | | | | | | | | The previous code resulted in that all regions that had some alpha blending content had to be rasterized as bitmaps. With this patch, we only need to fallback to proper alpha blending if there is a background content to blend against. If there is no background content we simly assume that the background is white (which happen to be the most common paper color). It will then be treated as a solid background.
