* Revert "Move coverage bitmap from FontCollection to FontFamily"stable/cm-12.0-YNG4Nstable/cm-12.0-YNG3Cstable/cm-12.0-YNG1TAstable/cm-12.0-YNG1Tstable/cm-12.0-YNG1Icm-12.0Steve Kondik2015-02-261-21/+0
| | | | | | | | * Seeing sporadic crashes with this patch. Reverting for now. This reverts commit 4e4ab1a6c8347e977245d1126d10e48a3412d35d. Change-Id: Ibcda62e8268e9a5559c0517695fa61f36f0d34d0
* Move coverage bitmap from FontCollection to FontFamilyRaph Levien2015-02-131-0/+21
| | | | | | | | | | This will significantly reduce memory usage and also speed the creation of new font families. In particular, the coverage bitmaps for the fonts in the fallback stack will be computed once in the Zygote, rather than separately in each app process.

* Fine-tune fake-bolding conditionstaging/cm-12.0-cafRaph Levien2014-09-221-4/+4
| | | | | | | | | | The old logic for fake bolding results in no fake bolding for a bold span on a light weight (300) because the target weight (600 in this case) didn't meet the condition. This patch fine-tunes the threshold to enable fake bolding for this. Bug: 17587185 Change-Id: I04abd00a74240cbed79c417f81486aa2158b2806
* Towards CSS removalBehdad Esfahbod2014-07-241-1/+23
| | | | | | | Extract language from FontStyle during shaping. Don't attach CSS to LayoutContext. Change-Id: Ie621d3415410178d0d15fa7b810eb8e412342ab6
* Tighten requirements for fake boldRaph Levien2014-06-121-3/+5
| | | | | | | | | | | The simple predicate for fake bold (2 or more grades darker than requested) was applying it to thin (100 weight) when normal was requested. This patch tightens the predicate to also require that the requested weight be in the bold range. Fix for bug 15588352 "sans-serif-thin doesn't work on lockscreen" Change-Id: Id9988bd149a9c8a7c943e3b221f7fb4b37fb6ddb
* Support for fake bold and italicsRaph Levien2014-06-101-3/+18
| | | | | | | | | | This patch adds support for computing when fake bold and fake italics are needed (because the styles are requested but not provided by the matching FontFamily), and providing them as part of the layout result. Part of the fix for bug 15436379 Fake bold doesn't fully work (Minikin) Change-Id: I180c034b559837943673b5c272c8e890178dff0d
* Language and variant selectionRaph Levien2014-05-291-0/+41
| | | | | | | | | | | | | | This patch adds a "lang" pseudo-CSS property and uses it both to select an appropriate font and control the "locl" OpenType feature to get the most appropriate rendering for the langauge and script. In addition, the "-minikin-variant" property selects between "compact" and "elegant" variants of a font, as the former is needed for vertically cramped spaces. This is part of the fix for bug 15179652 "Japanese font isn't shown on LMP". Change-Id: I7fab23c12d4c797a6d339a16e497b79a3afe9df1
* Fix incomplete refcounting and lockingRaph Levien2014-05-191-2/+9
| | | | | | | | These changes were supposed to be committed in the previous patch "Better refcounting and locking" but seem to have gotten lost in a rebase. It fixes a memory leak and some possible race conditions. Change-Id: I54ca1e37500ec49756fe317cc6d6d03da9911501
* Better refcounting and lockingRaph Levien2014-05-121-0/+7
| | | | | | | | | | | All major externally accessible objects (especially FontFamily and FontCollection) are now reference counted. In addition, there is a global lock intended to make operations thread-safe. WIP notice: in this version of the patch, not all external API entry points are protected by the lock. That should be fixed. Change-Id: I14106196e99eb101e8bf1bcb4b81359759d2086c
* A basket of features: itemization, bounds, refcountRaph Levien2014-05-121-1/+0
| | | | | | | | | | | | | | | This patch improves script run itemization and also exposes metrics and bounds for layouts. In addition, there is a fair amount of internal cleanup, including ref counting, and making the MinikinFont abstraction strong enough to support both FreeType and Skia implementations. There is also a sample implementation using Skia, in the sample directory. As part of its functionality, his patch measures the bounds of the layout and gives access through Layout::GetBounds(). The corresponding method is not implemented in the FreeType-only implementation of MinikinFont, so that will probably have to be fixed. Change-Id: Ib1a3fe9d7c90519ac651fb4aa957848e4bb758ec

* Introduce MinikinFont abstractionRaph Levien2013-06-141-13/+11
| | | | | | | | | | | This commit removes the direct dependency on FreeType and replaces it with a MinikinFont abstraction, which is designed to support both FreeType and Skia fonts (and possibly others in the future). Also adds a "total advance" to the Layout, with an API for retrieving it. Change-Id: If20f92db9a43fd15b0fe9794b761ba00fb21338c
* Initial commit of Minikin libraryRaph Levien2013-04-251-0/+95
This is the initial draft of Minikin, a library intended to perform text layout functions. This version does basic weight selection and font runs for scripts, and also has a simple renderer for drawing into bitmaps, but is lacking measurement, line breaking, and a number of other important features. It also lacks caching and other performance refinements. Change-Id: I789a2e47d11d71202dc84b4751b51a5e2cd9c451
