* Update Harfbuzz to 7.0.1Eskil Abrahamsen Blomfeldt2023-03-011-1/+0
| | | | | | | | | | | Note: 6.4.x update has to be done in a separate commit because it did not get the update to 6.0.0, so the cherry-pick will not apply.

* Update Harfbuzz to version 6.0.0Eskil Abrahamsen Blomfeldt2023-01-311-45/+24
| | | | | | | | | | | | | | | | Note: This requires an update to the tst_qtextlayout test, because the test assumed that the Arabic string would always yield a run of two glyphs. This was a side effect of how Harfbuzz handled Qt's test font, which has zero font tables and cannot be used for shaping. With the Harfbuzz update, the Arabic text here yields a single cluster instead, which actually makes more sense, so the test has been made a bit more robust to support both cases.

* Update to Harfbuzz 2.6.4Eskil Abrahamsen Blomfeldt2020-03-041-400/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quite a big change since it has been several years since the last update. This drops the Harfbuzz source on top of the existing code in Qt, and does the following additional changes: 1. Deletes old source files that have been removed upstream (everything named foo-private.hh is now renamed to just foo.hh for instance). 2. Added a header guard to config.h because it may be double-included. 3. Implement a memory barrier needed by hb-atomic.hh. 4. Changed the signature of hb_atomic_int_impl_add() to take a pointer to match new upstream. 5. Updated .pro file to include new files and removed old. 6. Updated qt_attribution.json 7. No longer disable deprecated APIs since hb_ot_tags_from_script() is now deprecated and is used from Qt code. 8. Updated and applied the patch in patches/ for CoreText. 9. Updated tst_qtextscriptengine::thaiWithZWJ() according to changes in Harfbuzz and disabled it for system-harfbuzz, since this may be an older version of harfbuzz depending on the system.

* harbuzzng: Remove assumption about Core Text working in 96 DPITor Arne Vestbø2019-02-111-21/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Core Text doesn't actually have a concept of DPI internally, as it doesn't rasterize anything by itself, it just generates vector paths that get passed along to Core Graphics. In practice this means Core Text operates in the classical macOS logical DPI of 72, with one typographic point corresponding to one point in the Core Graphics coordinate system, which for a normal bitmap context then corresponds to one pixel -- or two pixels for a "retina" context with a 2x scale transform. Scaling the font point sizes given to HarfBuzz to an assumed DPI of 96 is problematic with this in mind, as fonts with optical features such as 'trak' tables for tracking, or color glyphs, will then base the metrics off of the wrong point size compared to what the client asked for. This in turn causes mismatches between the metrics of the shaped text and the actual rasterization, which doesn't include the 72 to 96 DPI scaling. If a 96 DPI is needed, such as on the Web, the scaling should be done outside of HarfBuzz, allowing the client to keep the DPI of the shaping in sync with the rasterization. The recommended way to do that is by scaling the font point size, not by applying a transform to the target Core Graphics context, to let Core Text choose the right optical features of the target point size, as described in WWDC 2015 session 804: https://developer.apple.com/videos/play/wwdc2015/804/ GitHub-PR: https://github.com/harfbuzz/harfbuzz/pull/1484 Change-Id: I830f0cd7a82552422bbe09226e2d571e246fe3f4 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>

* HB-NG w/CoreText backend: Fix clustering of neutral charactersEskil Abrahamsen Blomfeldt2014-04-091-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Say you have a string with logical contents "abc ABC, " where lowercase is LTR and uppercase is RTL. In this case, the UBA will give "abc " LTR direction, and "ABC, " will get RTL. However, our itemization currently divides "ABC, " into two script items: "ABC" and ", ". CoreText will return glyphs in visual order, so for the first we will get "CBA" and for the second we will get ", ". But as the ", " item has an adapted directionality of RTL in the context of the full paragraph, it should actually be " ," visually. This caused a mismatch which broke the tst_QComplexText test with HB-NG using CoreText backend. As a temporary fix for this, we check whether the directionality of the first run in the text is different from the directionality expected by HB-NG. If this happens, it means the order of the glyphs produced by CoreText will be the reverse order of what is expected by HB-NG, and we therefore need to reverse it.

* HB-NG on Mac: Fix PDF in end of stringEskil Abrahamsen Blomfeldt2014-04-081-2/+22
| | | | | | | | | | | | | | | The CoreText engine will remove the PDF token from the end of the string (instead of producing a zero-width glyph for it), thus the output will be different from the OpenType backend and Qt will get confused.

* Fix bundled HarfBuzz-NG build outside QtGuiKonstantin Ritt2014-03-191-22/+24
| | | | | | | | | | | | | | On Mac, hb_coretext requires both CTFont and CGFont. Due to not supporting the 0 tag by CoreText, hb_blob_get_data() always fails causing the hb_coretext_shaper initialization to fail, too. Since HarfBuzz-NG is not a part of QtGui module anymore, there are two possibilities to workaround this: either engineer the font data by querying tables one-by-one and generating the font directory table, or pass CTFont and CGFont refs directly to hb_coretext via the hb_face's user_data. This patch implements the latter. Change-Id: I7d2e2df00818ea811642cb6a6c3b9c9abd5d7b94 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
