## Version 1.10 (2023-01-15) - Switched to vcpkg as the primary dependency management system - Switched to libpng as the primary PNG file encoder - Parameters of variable fonts can be specified - Fixed a bug that prevented glyph 0 to be specified in a glyphset ### Version 1.9.2 (2021-12-01) - Improved detection of numerical errors in cubic equation solver - Added -windingpreprocess option - Fixed edge coloring not restored if lost during preprocessing ### Version 1.9.1 (2021-07-09) - Fixed an edge case bug in the new MSDF error correction algorithm ## Version 1.9 (2021-05-28) - Error correction of multi-channel distance fields has been completely reworked - Added new edge coloring strategy that optimizes colors based on distances between edges - Added some minor functions for the library API - Minor code refactor and optimizations ## Version 1.8 (2020-10-17) - Integrated the Skia library into the project, which is used to preprocess the shape geometry and eliminate any self-intersections and other irregularities previously unsupported by the software - The scanline pass and overlapping contour mode is made obsolete by this step and has been disabled by default. 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.
