9ac9060d	2018-06-03T09:01:17	[GSoC] src/.: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
ae248034	2018-06-02T21:42:44	[smooth] Attempt to mitigate bug #54019. The robust rendering of estra large glyphs came with unbearable cost. The old way of bisecting should fail but fail faster. * src/smooth/ftgrays.c (gray_convert_glyph): Switch back to bisecting in y-direction.
95149592	2018-05-02T20:27:48	Remove FT_CONFIG_OPTION_PIC and related code. / [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. /: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed.

ab6fe076	2017-11-06T21:34:56	* src/smooth/ftgrays.c (gray_set_cell): Fix uninitialized variables.
81651636	2017-11-01T22:51:03	[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.
91015cb4	2017-10-21T22:57:43	[smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size. Reported, analyzed, and tested by Colin Fahey. * src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells.
6bea49e0	2017-10-14T22:45:11	[base] Netpbm image tracing. * src/base/ftobjs.c (FT_Load_Glyph): Trace bitmap size. (FT_Render_Glyph_Internal): Trace bitmap in Netpbm format. * src/smooth/ftgrays.c (gray_sweep): Sweep remnants of span tracing.

6ca54c64	2016-09-11T16:00:52	[smooth] Fix valgrind warning and reoptimize. The algorithm calls `gray_set_cell' at the start of each new contour or when the contours cross the cell boundaries. Double-checking for that is wasteful. * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell. (gray_convert_glyph): Remove initialization introduced by 44b172e88.
a0b92bcb	2016-09-07T23:19:57	* src/smooth/ftgrays.c (gray_hline): Microptimize.
9d0a3bd8	2016-09-06T23:59:33	[smooth] Operate in absolute bitmap coordinates. Simpler bitmap addressing improves performance by 1.5%. * src/smooth/ftgrays.c (gray_TWorker): Remove count fields. (gray_dump_cells, gray_find_cell, gray_set_cell, gray_hline, gray_sweep, gray_convert_glyph, gray_raster_render): Updated.
44b172e8	2016-09-06T23:24:17	[smooth] Improve contour start (take 2). * src/smooth/ftgrays.c (gray_move_to): Call `gray_set_cell' directly instead of... (gray_start_cell): ... this function, which is removed. (gray_convert_glyph): Make initial y-coordinate invalid.

16583ccd	2016-09-02T22:45:14	* src/smooth/ftgrays.c (gray_hline): Fix clang compiler warnings.
11d3336a	2016-09-01T22:56:24	[smooth] Simplify span rendering more. It turns out that there is significant cost associated with `FT_Span' creation and calls to `gray_render_span' because it happerns so frequently. This removes these steps from our internal use but leaves it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain is about 5%. * src/smooth/ftgrays.c (gray_render_span): Removed. The code is migrated to... (gray_hline): ... here.
f44ddfda	2016-08-30T23:21:23	[smooth] Streamline pixmap drawing a bit more. Zero coverage is unlikely (1 out of 256) to warrant checking. This gives 0.5% speed improvement in dendering simple glyphs. * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
e73055c7	2016-08-29T23:15:35	[smooth] Streamline pixmap drawing. This gives 2% speed improvement in rendering simple glyphs. * src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a pointer to its bottom-left and pitch to be used in... (gray_TWorker): ... here. (gray_render_span): Move pixmap flow check from here... (gray_raster_render): .. to here.
4d3f7ca8	2016-08-27T23:25:54	[smooth] Reduce stack of band boundaries. * src/smooth/ftgrays.c (gray_TBand): Removed. (gray_convert_glyph): Updated to stack band boundaries concisely.
9a444f05	2016-08-25T22:36:01	* src/smooth/ftgrays.c (gray_raster_render): Minor tweaks.
cb438878	2016-08-22T23:06:45	[smooth] Simplify span rendering. This removes unnecessary complexity of span merging and buffering. Instead, the spans are rendered as they come, speeding up the rendering by about 5% percents as a result. * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed. (gray_TWorker): Remove span buffer and related fields. (gray_sweep, gray_hline): Updated. * include/freetype/ftimage.h: Remove documentation note about `FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone.
3b37bfc4	2016-08-10T22:38:08	* src/smooth/ftgrays.c (gray_hline): Fix uninitialized access.
97718f3c	2016-08-05T23:36:16	[smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line): Updated.

109d1662	2016-07-08T06:58:46	Revert "Formatting." This reverts commit a0f3a1f25a69a7c5268e87ee6e7a9238c26e6242.

4a2f8f1f	2016-07-08T00:16:07	[smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol.
d1876e58	2016-07-04T23:46:53	[smooth] Variable type revision (part 2). * src/smooth/ftgrays.c (TArea): Restore original definition as `int'. (gray_render_line) [FT_LONG64]: Updated. (gray_convert_glyph): 32-bit band bisection stack should be 32 bands. (gray_convert_glyph_inner): Trace successes and failures.
597c6959	2016-07-01T23:27:41	[smooth] Variable type revision (part 1). This patch restores original `TCoord' definition as `int' so that the rendering pool is used more efficiently on LP64 platforms (unix). * src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some fields to `TCoord'. (gray_find_cell, gray_render_scanline, gray_render_line, gray_hline, gray_sweep, gray_convert_glyph): Updated.
ef0a3e7e	2016-06-28T22:56:22	[smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_TWorker): Remove redundant `ycount'. (gray_sweep, gray_convert_glyph, gray_dump_cells): Updated.
c9cf359f	2016-06-28T00:30:58	[smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_convert_glyph): Do not use volatile qualifier. (gray_raster_render): Move span initializations from here. (gray_sweep): ... to here and remove unused `target' argument.
25e82bc2	2016-06-23T23:17:39	[smooth] Consolidate memory management. * src/smooth/ftgrays.c (gray_init_cells): Remove function. (gray_TWorker): Remove fields that become local variables.

e2233481	2016-06-22T23:14:26	[smooth] Consolidate boundary checks. Removing the checks from `gray_hline' shaves 1% off rendering speed. * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_MIN' and `FT_MAX'. (gray_TWorker): No need to store `clip_box'. (gray_hline): Remove unnecessary boundary checks. (gray_convert_glyph): Move boundary checks from here. (gray_raster_render): ... to here and consolidate.
78e8fc0d	2016-06-22T00:04:08	[smooth] Use `FT_Outline_Get_CBox'. * src/smooth/ftgrays.c [STANDALONE_]: Duplicate `FT_Outline_Get_CBox'. (gray_compute_cbox): Remove this function. (gray_convert_glyph): Update to use `FT_Outline_Get_CBox'.
20c6ef4c	2016-06-21T11:39:34	[smooth] Remove compiler warnings. * src/smooth/ftgrays.c (gray_convert_glyph): Fix reports from clang.
3c64af98	2016-06-20T00:01:55	[smooth] Sanitize memory managenent. * src/smooth/ftgrays.c (gray_convert_glyph): Cleaned up.

e9f95093	2016-05-26T23:46:38	[smooth] Shrink bisection stack. The convergence of Bézier flatteners is fast with the deviation from straight line being assymptotically cut 4-fold on each bisection. This justifies smaller bisection stack size. * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'. (gray_render_conic): Create and use conic `bez_stack'. Move back the band analysis from... (gray_conic_to): ... here. (gray_render_cubic): Create and use cubic `bez_stack'. Move back the band analysis from... (gray_cubic_to): ... here. (gray_move_to): Updated.
6e88087d	2016-05-05T23:41:03	[smooth] More efficient accounting of conic splits and draws. A single decrement counter of segments to draw, instead of an array, contains all the information necessary to decide when to split and when to draw a conic segment. The number of splits before each draw is equal to the number of trailing zeros in the counter. * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'. (gray_render_conic): Updated to use decrement counter of segments.

e9181aba	2016-03-23T06:58:20	[raster, smooth] Fix some clang sanitizer runtime issues. * src/raster/ftraster.c (ft_black_reset, ft_black_set_mode, ft_black_render): Harmonize signatures with `ftimage.h'. * src/smooth/ftgrays.c (gray_raster_render, gray_raster_reset): Ditto.
3beccbdf	2016-03-21T00:07:47	[smooth] Partly revert recent changes. * src/smooth/ftgrays.c (gray_conic_to, gray_cubic_to): Rework conditions to fix rendering issues.

9d0b76d7	2016-01-12T22:27:29	Don't use macro names that start with `_[A-Z]' [2/3]. Such macro names are reserved for both C and C++. * include/freetype/ftimage.h, src/raster/ftraster.c, src/smooth/ftgrays.c, src/smooth/ftgrays.h: s/_STANDALONE_/STANDALONE_/.
6eb6158d	2015-10-06T22:39:54	[smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.
e2dae8fe	2015-10-01T22:03:34	[smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove never used fields.

392cf22f	2015-06-25T13:04:57	Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated.

8502c98b	2015-06-22T06:35:23	Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/: Move to ... include/freetype2/: This directory, except `ft2build.h'. CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated.

b2ba6866	2015-01-14T18:43:13	[smooth] Fix uninitialized memory access. Looks like `ras.span_y' could always be used without initialization. This was never detected by valgrind before because the library-wide `raster_pool' was used for the worker object and `raster_pool' was originally zero'ed. But subsequent reuses of it were using `span_y' uninitialized. With the recent change to not use `render_pool' and allocate worker and buffer on the stack, valgrind now detects this uninitialized access. * src/smooth/ftgrays.c (gray_raster_render): Initialize `ras.span_y'.

[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool.

[smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol.

[smooth] More efficient accounting of conic splits and draws. A single decrement counter of segments to draw, instead of an array, contains all the information necessary to decide when to split and when to draw a conic segment. The number of splits before each draw is equal to the number of trailing zeros in the counter. * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'. (gray_render_conic): Updated to use decrement counter of segments.

[smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.

Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated. Update creation of `ftconfig.h'. Install generated `ftconfig.h'. * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. * builds/unix/configure.raw: Don't check for `rmdir'. * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable according to the autoconf info manual. * builds/unix/install.mk (install, uninstall, distclean_project_unix): Update and simplify. * builds/wince/*, builds/windows/*: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.

Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/*: Move to ... * include/freetype2/*: This directory, except `ft2build.h'. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. Emit -I directory only if it is not `/usr/include'. * builds/wince/*, builds/windows/*: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.

[smooth] Fix uninitialized memory access. Looks like `ras.span_y' could always be used without initialization. This was never detected by valgrind before because the library-wide `raster_pool' was used for the worker object and `raster_pool' was originally zero'ed. But subsequent reuses of it were using `span_y' uninitialized. With the recent change to not use `render_pool' and allocate worker and buffer on the stack, valgrind now detects this uninitialized access. * src/smooth/ftgrays.c (gray_raster_render): Initialize `ras.span_y'.
