* Harfbuzz-thai - fix buffer overflow when setting item attributesJohn Tapsell2012-03-141-0/+29

* Harfbuzz-shaper - fix incorrect logClusters being set in HB_OpenTypePositionJohn Tapsell2012-03-041-4/+12
| | | | | | | | | | | | | | After shaping in HB_OpenTypePosition, when we come to calculate the new logClusters array we have to take into account that the glyphs passed in are not a 1 to 1 correspondance with the original string, because some shaping might have already been done. So we must use the old logClusters values (stored in tmpLogClusters) to map from the glyphs passed in back to the original string. This fixes visual word wrapping problems in thai Change-Id: I384dfa98f0946e9e074728f89542acb2b6b6bc27 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>

| | | | | | | | | | | text when dividing up strings Many languages use a fullstop to indicate an abbreviation, making the fullstop part of the word. For languages like thai, it is required to pass the fullstop along for correct word breaking. Change-Id: Ideded63432d06a1ab3b786a7bd13356f2cc1a090 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
* Harfbuzz-thai: Hide ZWJ and ZWNJ characters and show Inherited charactersJohn Tapsell2012-02-101-0/+42
| | | | | | | | | | | | | | | | | | | | | | Thai is not supposed to have ZWJ and ZWNJ characters or any other of the Inherited Unicode Scripts (http://www.verisigninc.com/assets/idn-inherited-unicode-script.pdf) - they don't have a mapping to the thai encoding tis620 which libthai requires. However it is an unfortunate fact that there are many websites etc that liberally place these ZWJ and ZWNJ characters throughout thai text to force word boundaries, so we must also deal with them. We deal with all Inherited characters by mapping them to the invalid code ~0 in tis620 encoding, following what libthai does internally in its own tis620 encoding functions, and then replacing this character with the original unicode and setting dontPrint to true to hide the ZWJ and ZWNJ characters. Includes a unit test to check the behaviour. Change-Id: I49e44da6e39443daa832e7f50c94804e13deabb4 Reviewed-by: Adrian Yanes <ext-adrian.yanes@nokia.com> Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
* Fix isolated Thai SARA AM handlingJiang Jiang2012-01-181-0/+25
| | | | | | | | | | | | | | Since 5e07a3ac58f93bd5e09715d43b58c20950c2befa Thai text layout is handled by libthai to special case of the SARA AM. It didn't handle isolated SARA AM. This patch fixed it and added detailed explaination on the special case. The dotted circle should be shown rather than hidden. Added a test case to verify that with Waree.

* Introduce QFontEngineDirectWriteEskil Abrahamsen Blomfeldt2011-03-141-0/+60
| | | | | | | | | | | | | | | | Make a font engine for subpixel positioned text on Windows Vista (with platform update) and Windows 7. If selected during configuration, the engine will be selected only when the hinting preference of a font is set to None or Vertical hinting. The font database uses most of the same logic but creates a direct write font based on the LOGFONT rather than a GDI handle. The engine is currently regarded as experimental, meaning that code using it should do substantial testing to make sure it covers their use cases. Task-number: QTBUG-12678 Reviewed-by: Jiang Jiang

| | | | | | | | | | | | | | When an autotest fails to compile, there's no way to determine which testcase(s) have been prevented from running. Our results parsing tools have been guessing, under the assumption that a directory called `qdogwalker' always contains a testcase named `tst_qdogwalker'. That wasn't true for all our tests, so let's make it true. Also changed the platform-specific tests so that qmake will simply skip those tests on unsupported platforms, instead of wasting time compiling a useless QTEST_NOOP_MAIN test.
