The preprocess step can be disabled by the new `-nopreprocess` switch and the former enabled by `-scanline` and `-overlap` respectively. - - The project can be built without the Skia library, forgoing the geometry preprocessing feature. This is controlled by the macro definition `MSDFGEN_USE_SKIA` -- Significantly improved performance of the core algorithm by reusing results from previously computed pixels -- Introduced an additional error correction routine which eliminates MSDF artifacts by analytically predicting results of bilinear interpolation -- Added the possibility to load font glyphs by their index rather than a Unicode value (use the prefix `g` before the character code in `-font` argument) -- Added `-distanceshift` argument that can be used to adjust the center of the distance range in the output distance field -- Fixed several errors in the evaluation of curve distances -- Fixed an issue with paths containing convergent corners (those whose inner angle is zero) -- The algorithm for pseudo-distance computation slightly changed, fixing certain rare edge cases and improving consistency -- Added the ability to supply own `FT_Face` handle to the msdfgen library -- Minor refactor of the core algorithm - -### Version 1.7.1 (2020-03-09) - -- Fixed an edge case bug in scanline rasterization - -## Version 1.7 (2020-03-07) - -- Added `mtsdf` mode - a combination of `msdf` with `sdf` in the alpha channel -- Distance fields can now be stored as uncompressed TIFF image files with floating point precision -- Bitmap class refactor - template argument split into data type and number of channels, bitmap reference classes introduced -- Added a secondary "ink trap" edge coloring heuristic, can be selected using `-coloringstrategy inktrap` -- Added computation of estimated rendering error for a given SDF -- Added computation of bounding box that includes sharp mitered corners -- The API for bounds computation of the `Shape` class changed for clarity -- Fixed several edge case bugs - -## Version 1.6 (2019-04-08) - -- Core algorithm rewritten to split up advanced edge selection logic into modular template arguments. -- Pseudo-distance evaluation reworked to eliminate discontinuities at the midpoint between edges. -- MSDF error correction reworked to also fix distances away from edges and consider diagonal pairs. Code simplified. -- Added scanline rasterization support for `Shape`. -- Added a scanline pass in the standalone version, which corrects the signs in the distance field according to the selected fill rule (`-fillrule`). Can be disabled using `-noscanline`. -- Fixed autoframe scaling, which previously caused the output to have unnecessary empty border. -- `-guessorder` switch no longer enabled by default, as the functionality is now provided by the scanline pass. -- Updated FreeType and other libraries, changed to static linkage -- Added 64-bit and static library builds to the Visual Studio solution - -## Version 1.5 (2017-07-23) - -- Fixed rounding error in cubic curve splitting. -- SVG parser fixes and support for additional path commands. -- Added CMake build script. - -## Version 1.4 (2017-02-09) - -- Reworked contour combining logic to support overlapping contours. Original algorithm preserved in functions with `_legacy` suffix, which are invoked by the new `-legacy` switch. -- Fixed a severe bug in cubic curve distance computation, where a control point lies at the endpoint. -- Standalone version now automatically detects if the input has the wrong orientation and adjusts the distance field accordingly. Can be disabled by `-keeporder` or `-reverseorder` switch. -- SVG parser fixes and improvements. - -## Version 1.3 (2016-12-07) - -- Fixed `-reverseorder` switch. -- Fixed glyph loading to use the proper method of acquiring outlines from FreeType. - -## Version 1.2 (2016-07-20) - -- Added option to specify that shape vertices are listed in reverse order (`-reverseorder`). -- Added option to set a seed for the edge coloring heuristic (-seed \), which can be used to adjust the output. -- Fixed parsing of glyph contours that start with a curve control point. - -## Version 1.1 (2016-05-08) - -- Switched to MIT license due to popular demand. -- Fixed SDF rendering anti-aliasing when the output is smaller than the distance field. - -## Version 1.0 (2016-04-28) - -- Project published. diff --git a/thirdparty/msdfgen/LICENSE.txt b/thirdparty/msdfgen/LICENSE.txt index 5fb05446bcd..9757001664a 100644 --- a/thirdparty/msdfgen/LICENSE.txt +++ b/thirdparty/msdfgen/LICENSE.txt @@ -1,6 +1,6 @@ MIT License -Copyright (c) 2016 Viktor Chlumsky +Copyright (c) 2016 - 2022 Viktor Chlumsky Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal diff --git a/thirdparty/msdfgen/core/SignedDistance.cpp b/thirdparty/msdfgen/core/SignedDistance.cpp index 18c9d2c4244..be956d953e1 100644 --- a/thirdparty/msdfgen/core/SignedDistance.cpp +++ b/thirdparty/msdfgen/core/SignedDistance.cpp @@ -2,12 +2,11 @@ #include "SignedDistance.h" #include +#include namespace msdfgen { -const SignedDistance SignedDistance::INFINITE(-1e240, 1);
