Werner Lemberg a0dd16fb 2018-08-15T18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.
Alexei Podtelezhnikov e16bfbec 2018-08-09T22:18:00 [raster, smooth] Reinstate bitmap size limits. This again moves outline and bitmap size checks one level up. * src/base/ftoutln.c (FT_Outline_Render): Explicitly reject enormous outlines. * src/raster/ftrend1.c (ft_raster1_render): Reject enormous bitmaps and, therefore, outlines that require them. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto. * src/raster/ftraster.c (ft_black_render): Remove outline size checks. * src/smooth/ftgrays.c (gray_raster_render): Ditto. [STANDALONE]: Remove `FT_Outline_Get_CBox' copy.
Werner Lemberg f60c98fe 2018-08-08T18:15:53 [smooth] Improve tracing. * src/smooth/ftgrays.c (gray_convert_glyph_inner): Only use tracing if called the first time. (gray_convert_glyph): Updated.
Werner Lemberg ca4e707a 2018-06-06T08:18:23 [smooth, raster] Limit bitmap size (#54019). * src/raster/ftraster.c [STANDALONE] (FT_Outline_Get_CBox): Add function. [!STANDALONE]: Include FT_OUTLINE_H. (ft_black_render): Compute CBox and reject glyphs larger than 0xFFFF x 0xFFFF. * src/smooth/ftgrays.c (gray_raster_render): Reject glyphs larger than 0xFFFF x 0xFFFF.

Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Werner Lemberg 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.

Werner Lemberg 71fecc53 2017-12-05T12:06:29 Improve tracing messages by using singular and plural forms. * src/*/*.c: Implement it.
Werner Lemberg 87ddad20 2017-12-04T20:43:30 Update or fix links to use the https protocol instead of http.
Alexei Podtelezhnikov ab6fe076 2017-11-06T21:34:56 * src/smooth/ftgrays.c (gray_set_cell): Fix uninitialized variables.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.

Alexei Podtelezhnikov ad47550b 2016-09-14T23:15:03 [smooth] Another tiny speed-up. * src/smooth/ftgrays.c (gray_find_cell): Merge into... (gray_record_cell): ... this function.
Alexei Podtelezhnikov c38be52b 2016-09-11T22:44:44 * src/smooth/ftgrays.c (gray_{find,set}_cell): Remove dubious code.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov a0b92bcb 2016-09-07T23:19:57 * src/smooth/ftgrays.c (gray_hline): Microptimize.
Alexei Podtelezhnikov 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.

Alexei Podtelezhnikov 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.

Werner Lemberg 16583ccd 2016-09-02T22:45:14 * src/smooth/ftgrays.c (gray_hline): Fix clang compiler warnings.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 9a444f05 2016-08-25T22:36:01 * src/smooth/ftgrays.c (gray_raster_render): Minor tweaks.
Alexei Podtelezhnikov 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.
Peter Klotz 3b37bfc4 2016-08-10T22:38:08 * src/smooth/ftgrays.c (gray_hline): Fix uninitialized access.
Alexei Podtelezhnikov 97718f3c 2016-08-05T23:36:16 [smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line): Updated.

Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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. (gray_raster_render): Move rendering buffer declaration from here. (gray_convert_glyph): ... to here and update accordingly.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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'.
Werner Lemberg 20c6ef4c 2016-06-21T11:39:34 [smooth] Remove compiler warnings. * src/smooth/ftgrays.c (gray_convert_glyph): Fix reports from clang.
Alexei Podtelezhnikov 3c64af98 2016-06-20T00:01:55 [smooth] Sanitize memory managenent. * src/smooth/ftgrays.c (gray_convert_glyph): Cleaned up.
Alexei Podtelezhnikov 74fd251b 2016-06-18T22:31:26 [smooth] Remove `band_shoot' that never worked. * src/smooth/ftgrays.c (gray_TWorker): Remove `band_shoot'. (gray_convert_glyph): Updated.

Alexei Podtelezhnikov 72a06531 2016-06-17T23:10:22 [raster, smooth] Handle FT_RENDER_POOL_SIZE better. * src/raster/ftraster.c (FT_MAX_BLACK_POOL): New macro. (ft_black_render): Updated. * src/smooth/ftgrays.c (FT_MAX_GRAY_POOL): New macro. (gray_raster_render): Updated.

Alexei Podtelezhnikov 9cf232ed 2016-06-08T23:19:41 [smooth] Minor clean-ups. * src/smooth/ftgrays.c (gray_dump_cells): Move out of the way. (gray_render_span): Remove spurious casts and streamline.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.

Werner Lemberg 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.
Alexei Podtelezhnikov 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.

Werner Lemberg 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_/.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov e2dae8fe 2015-10-01T22:03:34 [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove never used fields.
Alexei Podtelezhnikov 8bbcfb2c 2015-09-30T23:08:53 [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove lightly used `last_ey'. (gray_start_cell, gray_render_line): Update.

Werner Lemberg 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. 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.
Werner Lemberg 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. 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.

Behdad Esfahbod 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'.
Behdad Esfahbod 747ae2c8 2015-01-14T17:54:26 [smooth] Allocate render pool for smooth rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the smooth rasterizer.

(gray_raster_render): Create `buffer', `buffer_size', and `band_size' locally. (gray_raster_reset): Updated.
