2022-07-29BLF: Fonts with FT_Face OptionalHarley Acheson
Allow FontBLFs to exist with NULL FT_Face, added only when actually needed. Speeds up startup and unused fonts are not loaded. See D15258 for more details. Differential Revision: https://developer.blender.org/D15258 Reviewed by Brecht Van Lommel
2022-07-07BLF: Add Support for Variable FontsHarley Acheson
Add support for Variable/Multiple Master font features. These are fonts that contain a range of design variations along multiple axes. This contains no client-facing options. See D12977 for details and examples Differential Revision: https://developer.blender.org/D12977 Reviewed by Brecht Van Lommel

2022-06-17BLF: Fallback Font StackHarley Acheson

2022-04-14Fix T97310: BLF Line Height While Text WrappingHarley Acheson
Fix word-wrapped tooltip text not showing by aligning to pixel grid. See D14639 for more details. Differential Revision: https://developer.blender.org/D14639 Reviewed by Campbell Barton
2022-04-13Cleanup: avoid redundant float/int conversions in BLFCampbell Barton
Internally many offsets for BLF were integers but exposed as floats, since these are used in pixel-space, many callers were converging them back to integers. Simplify logic by using ints.
2022-04-13BLF: sub-pixel positioning supportCampbell Barton
Support sub-pixel kerning and hinting for future support for improved character placement. No user visible changes have been made. - Calculate sub-pixel offsets, using integer maths. - Use convenience functions to perform the conversions and hide the underlying values. - Use `ft_pix` type to distinguish values that use sub-pixel integer values from freetype and values rounded to pixels. This was originally based on D12999 by @harley with the user visible changes removed so they can be applied separately.
2022-03-24Cleanup: use "filepath" instead of "filename" for full pathsCampbell Barton
Reserve "filename" when only the name component is used.
2022-02-11File headers: SPDX License migrationCampbell Barton
Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069
2022-02-05BLF: Save fixed_width value in cacheHarley Acheson
Cache the font size's ideal fixed width column size in the glyph cache rather than the font itself to improve performance. See D13226 for more details. Differential Revision: https://developer.blender.org/D13226 Reviewed by Campbell Barton
2021-11-13BLF: Use Floats for Font Point SizesHarley Acheson
Allow the use of floating-point values for font point sizes, which allows greater precision and flexibility for text output. See D8960 for more information, details, and justification. Differential Revision: https://developer.blender.org/D8960 Reviewed by Campbell Barton
2021-11-03BLF: Remove Thread Locking For Font MetricsHarley Acheson
This patch removes the need to lock the thread just to get to some generic (not glyph-specific) font metrics. See D12976 for more details. Differential Revision: https://developer.blender.org/D12976 Reviewed by Campbell Barton

2021-08-21Refactor: BLF Kerning Cache After UseHarley Acheson
Optimization of font kerning by only caching kerning values after a pair is encountered. Also saves unscaled values so they don't have to be rebuilt between font size changes. See D12274 for more details and speed comparison. Differential Revision: https://developer.blender.org/D12274 Reviewed by Campbell Barton
2021-08-19Refactor: BLF Without Kerning ModesHarley Acheson

2021-08-16Cleanup: rename kerning table to ascii_tableCampbell Barton
It wasn't obvious this was only for ASCII characters.
2021-08-14BLF: Do Not Preload Glyph CacheHarley Acheson
This patch turns off the preloading of ascii glyphs and instead caches each glyph the first time it is actually used. See D12215 for much more detail. Differential Revision: https://developer.blender.org/D12215 Reviewed by Campbell Barton
2021-08-14BLF Cleanup: Size Defines, Comments, etcHarley Acheson
This patch makes some non-functional changes to BLF code. Some size defines added, comments changed, simplification of macro BLF_KERNING_VARS. See D12200 for more details. Differential Revision: https://developer.blender.org/D12200 Reviewed by Campbell Barton
2021-08-11BLF: Do Not Cache Unused Rendered GlyphsHarley Acheson
The loading of a font size or style renders bitmaps of the characters 0-255 and stores them in a cache. But glyphs 128-255 in this cache are not accessible. What used to be ansi high-bit characters are now multi- byte UTF-8 sequences. Therefore this patch reduces the glyph_ascii_table size to 128 and only caches characters 32-127, the visible portion of ASCII, which greatly reduces the time to load a font. See D12189 for more details. Differential Revision: https://developer.blender.org/D12189 Reviewed by Campbell Barton
2020-08-07Code Style: use "#pragma once" in source directoryJacques Lucke
This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`. Differential Revision: https://developer.blender.org/D8466

2020-02-24BLF: Optimize text rendering and cachingGermano Cavalcante
The current code allocates and transfers a lot of memory to the GPU, but only a small portion of this memory is actually used. In addition, the code calls many costly gl operations during the caching process. This commit significantly reduce the amount of memory by allocating and transferring a flat array without pads to the GPU. It also calls as little as possible the gl operations during the cache. This code also simulate a billinear filter `GL_LINEAR` using a 1D texture. **Average drawing time:** |before:|0.00003184 sec |now:|0.00001943 sec |fac:|1.6385156675048407 **5 worst times:** |before:|[0.001075, 0.001433, 0.002143, 0.002915, 0.003242] |now:|[0.00094, 0.000993, 0.001502, 0.002284, 0.002328] Differential Revision: https://developer.blender.org/D6886

2019-09-14BLF: make library glyph cache handling thread-safeRichard Antalik
Functions that utilize glyph cache should lock and unlock cache by calling `blf_glyph_cache_acquire()` and `blf_glyph_cache_release()`. Function `blf_glyph_cache_acquire()` will create glyph cache, if it doesn't exist. Locking mutex is global and shared by all fonts.

2019-02-01Cleanup: remove redundant, invalid info from headersCampbell Barton
BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.

2018-04-08BLF: Fix problem with bound texture.Clément Foucault
Previous code was assuming that the glyph texture would remain bound to GL_TEXTURE0 until the cache would be drawn. This is not always the case, so better save the texture and rebind it before drawing.
2018-04-01Merge branch 'master' into blender2.8Campbell Barton
- Undo that changes modes currently asserts, since undo is now screen data. Most likely we will change how object mode and workspaces work since it's not practical/maintainable at the moment. - Removed view_layer from particle settings (wasn't needed and complicated undo).
2018-03-31BLF: Perf: Add a kerning cache table for ascii chars.Clément Foucault
This adds less than a megabyte of mem usage. FT_Get_Kerning was the 2nd hotspot when profilling. This commit completly remove this cost. One concern though: I don't know if the kerning data is constant for every sizes but it seems to be the case. I tested different fonts at different dpi scalling and saw no differences.

I've made a separate version of the geom shader that works with full 3D modelviewmat. This commit also includes some fixup inside blf_batching_start().
2018-03-30BLF: Add Batching capabilities.Clément Foucault
You can now use BLF_batching_start and BLF_batching_end to batch every drawcall to BLF together minimizing the overhead introduced by BLF and the opengl driver. These calls cannot be nested (for now). If the modelview matrix changes, previously batched calls are issued and a the process resume with the new matrix. However the projection matrix MUST not change and gl scissors as well.
