2149b51f | 2021-03-13 19:08:09 | Handle various VC++ compiler warnings. Fixes #1039. * src/base/ftstroke.c (ft_stroker_inside, ft_stroker_outside): Initialize `sigma`. * src/sdf/ftsdf.c (sdf_generate_with_overlaps): Exit immediately if function arguments are invalid. * src/sdf/ftsdfrend.c (sdf_property_set) <"overlaps">: Fix cast. * src/sfnt/sfwoff2.c (woff2_decompress) [!FT_CONFIG_OPTION_USE_BROTLI]: Use `FT_UNUSED`. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Initialize `fvar_head`. | |
 |
7ae5609d | 2021-01-27 16:08:08 | * src/base/ftstroke.c (FT_Stroker_EndSubPath): Ignore tiny gaps. Fixes bug #1020. | |
|
4c3bd2ab | 2021-01-27 15:54:34 | [stroker] Minor clean-up. * src/base/ftstroke.c (FT_Stroker_{ConicTo,CubicTo}): Reset the last line length. (FT_Stroker_EndSubPath): Call `ft_stroker_process_corner'. | |
|
b6e8a712 | 2021-01-17 07:18:48 | Update all copyright notices. | |
|
16586859 | 2020-06-13 21:15:45 | Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'. | |
 |
e1339133 | 2020-06-08 13:31:55 | Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation. | |

9ac9060d | 2018-06-03 09:01:17 | [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. | |

b24e8ba2 | 2014-11-25 08:30:49 | [Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it. | |
|
0e73d218 | 2014-11-09 01:27:38 | * src/base/ftstroke.c (ft_stroker_inside): Fix border intersections. One more place to check whether `radius' is zero. Problem reported by Marco Wertz <marco.wertz@gmx.de>. | |
|
89f50647 | 2013-03-14 17:50:49 | */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |
|
72e976d4 | 2012-11-27 21:18:34 | [ftstroke] Minor improvement. * src/base/ftstroke.c: Replace nested FT_DivFix and FT_MulFix with FT_MulDiv. | |

aecbfe1b | 2011-07-02 12:09:52 | [ftstroke] Major revision. The main problems ----------------- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter joins (not bevel joins) were generated. Indeed, the meanings of `miter' and `bevel' were incorrectly reversed (consistently) in both the code and comments. o The way bevel joins were constructed (whether specified explicitly, or created as a result of exceeding the miter limit) did not match what is required for stroked text in PostScript or PDF. The main fixes -------------- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been introduced to support PostScript and PDF miter joins. o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an alias for FT_STROKER_LINEJOIN_MITER. Additionally, a variety of stroking errors have been fixed. These would cause various artifacts (including points `at infinity'), especially when stroking poor quality fonts. See http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html for example documents. The FreeType stroker now produces results very similar to that produced by GhostScript and Distiller for these fonts. Other problems -------------- The following problems have been resolved: o Inside corners could be generated incorrectly. Intersecting the inside corner could cause a missing triangular area and other effects. The intersection point can only be used if the join is between two lines and both lines are long enough. The `optimization' condition in `ft_stroker_inside' has been corrected; this requires the line length to be passed into various functions and stored in `FT_StrokerRec'. o Incorrect cubic curves could be generated. The angle calculations in `FT_Stroker_CubicTo' have been corrected to handle the case of the curve crossing the +/-PI direction. o If the border radius was greater than the radius of curvature of a curve, then the negative sector would end up outside (not inside) the border. This situation is now recognized and the negative sector is circumnavigated in the opposite direction. (If round line joins are being used, this code is disabled because the line join will always cover the negative sector.) o When a curve is split, the arcs may not join smoothly (especially if the curve turns sharply back on itself). Changes in direction between adjacent arcs were not handled. A round corner is now added if the deviation from one arc to the next is greater than a suitable threshold. o The current direction wasn't retained if a the outline contained a zero length lineto or a curve that was determined to be `basically a point'. This could cause a spurious join to be added. o Cubics with close control points could be mishandled. All eight cases are now distinguished correctly. Other improvements ------------------ o Borders for cubic curves could be too `flat'. FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent this. o The handling and use of movable points has been simplified a little. o Various values are now computed only if the results are actually needed. o The directions of the outer and inner borders have been swapped, as recommended by Graham Asher. * src/base/ftstroke.c: Revised. * include/freetype/ftstroke.h: Updated. | |
