This is a small maintenance release that addresses the following issues:
- Fixed the computation of font sizes performed by the new PDF handler (issue #220).
- Fixed the
viewBoxcoordinates determined by the new PDF handler (issue #223).
- Improved the detection of font names used in PDF files (issue #224).
- Minor code improvements, increased compatibility with older GCC versions.
This is the first stable release of dvisvgm 3. An overview of the main changes and additions can be found in the announcement of pre-release version 3.0 below. Version 3.0.1 fixes several issues reported in the last weeks.
- Added support for the 64-bit Ghostscript library in TeX Live (patch sent by Akira Kakuto).
- MacTeX: explicitly lookup libgs in /usr/local/lib (issue #197).
- Fixed the character spacing when processing XDV glyph arrays. (issue #198).
- Fixed the invalid removal of non-redundant
clipPathelements in some cases if option
--optimizeis present (issue #203).
- Fixed the computation of the graphics extents printed to the console when using the
previewpackage (issue #209).
- Several improvements of the autotools scripts (thanks to Sam James).
- Improved the processing of fonts performed by the new PDF handler.
dvisvgm 3.0 is a new major version of the utility that’s still considered beta status. While the new version doesn’t bring many obvious new features, essential core functionality has changed under the hood. The following list gives an overview of the most important changes and additions.
- The previously bundled reduced FontForge library has been replaced with a dedicated font writer library used to create TrueType and WOFF files from the font data processed by dvisvgm.
- A new PDF handler based on mutool has been added to retain dvisvgm’s PDF conversion
functionality after the removal of Ghostscript’s old PDF interpreter
announced for version 10.1.0.
- The new handler supports all font options of dvisvgm, i.e. in contrast to the current Ghostscript-based PDF processor,
fonts can not only be embedded as paths but also as SVG, TTF, WOFF, and WOFF2 fonts (depending on options
- The new handler is still experimental and may contain bugs. Please report any issues via the issue tracker at GitHub.
- Not all PDF features are supported – either because there is no simple equivalent in SVG or because mutool doesn’t provide means to access the corresponding data. For example, Type 3 fonts and color gradients fills are not yet processed by dvisvgm’s new PDF handler.
- The former Ghostscript-based PDF handler is still available. It’s automatically invoked if dvisvgm finds a proper Ghostscript
version. Otherwise, it looks for the
mutoolexecutable through the system’s search path and uses the new handler in case it’s found. The desired PDF handler can also be selected by setting environment variable
- The new handler supports all font options of dvisvgm, i.e. in contrast to the current Ghostscript-based PDF processor, fonts can not only be embedded as paths but also as SVG, TTF, WOFF, and WOFF2 fonts (depending on options
--embed-bitmapshas been added to allow for embedding of external images referenced in DVI files into the generated SVG files. By default the SVG only contains a reference to the image.
- The optional filters
:oddhave been added to option
--pagewhich limit the given page ranges to even and odd page numbers respectively.
You can download the sources and pre-built binaries for MiKTeX from the project page at GitHub.
- Added processing of SVG
pathelements inserted by “raw” specials in order to treat them similar to generated ones.
- Added support for native font references lacking a file name suffix.
- Improved the lookup of native fonts.
- Improved the removal of redundant SVG group elements.
- Fixed the conversion of empty glyphs to TTF/WOFF data.
- Updated the bundled WOFF2 library.
- Added SVG optimizer module
reassign-clippathsthat searches for duplicate
clipPathelements, removes them, and updates the
- Replaced the method used to clip embedded EPS/PDF graphics that now usually results in faster rendering of the affected SVG sections.
- Fixed a regression regarding transformations of embedded EPS/PDF graphics.
This small release improves the clipping of embedded EPS/PDF graphics (issue #176).
