Dvisvgm Versions Save

This is the first stable release of dvisvgm 3. An overview of the main changes and additions can be found in the release notes of pre-release version 3.0. Version 3.0.1 fixes some 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 clipPath elements in some cases if option --optimize is present (issue #203).
• Fixed the computation of the graphics extents printed to the console when using the preview package (issue #209).
• Several improvements of the autotools scripts (thanks to Sam James).
• Improved the processing of fonts performed by the new PDF handler.

This is a public test version of a new major dvisvgm release. It's still in development and some functionality might not work properly yet. Here's a list of the mist important changes/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 keep dvisvgm's PDF conversion functionality available 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 --no-fonts and --font-format).
  • The new handler is still experimental and may contain bugs. Please report them here in the issue tracker if you found some.
  • 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.
  • The former PDF handler is still available. It's automatically invoked if a proper Ghostscript version is available. Otherwise, dvisvgm looks for mutool 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 DVISVGM_PDF_PROC to either gs or mutool.
• Option --embed-bitmaps has 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 :even and :odd have been added to option --page which limit the given page ranges to even and odd page numbers respectively.

• Added processing of SVG path elements 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.

• Fixed the size of bounding boxes applied when converting multiple pages (issue #182).
• Try to enable the old PDF interpreter when using Ghostscript >= 9.56.0. dvisvgm does not work with Ghostscript's new PDF interpreter.

• Added SVG optimizer module reassign-clippaths that searches for duplicate clipPath elements, removes them, and updates the clip-path references.
• 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).

• Enabled the evaluation of expression {?(...)} in special dvisvgm:rawdef (issue #175).
• Fixed a regression concerning the positioning of PDF graphics with special pdffile (issue #174).
• Fixed some build issues for older C++ compilers.

• Added the functionality to sequentially convert multiple EPS files given on the command-line.
• Added variables n and N to option --output that represent the number of the file currently being processed and the total number of input files given on the command-line, respectively.
• Fixed the selection of the hash algorithm set by option --page-hashes.
• Improved the computation of glyph heights and depths.
• The SVG optimizer now also simplifies transform attributes when collapsing group elements.
• Extended several paragraphs of the manual page with more detailed information on the corresponding topics.
• Updated the bundled xxHash library to version 0.8.1.
• Updated the bundled GoogleTest framework to version 1.11.0.

• Added transparency support for SVG elements created outside the PS handler (issue #148).
• Fixed a spacing issue caused by unexpected newline characters in SVG output.
• Fixed PostScript errors occurred when defining (yet unsupported) shading patterns.
• Fixed a bug that prevented proper coloring of PostScript tiling patterns (issue #158).
• Fixed graphics displacements that occurred if the PDF MediBox is not located at the origin.
• Fixed the handling of root directories of file paths.
• Improved the handling of drive letters (Windows only).
• Several code refactorings and improvements.

This is a small maintenance release.

• Fixed possible ambiguities of GID to charcode mappings (issue #147).
• Refactored the representation of token objects in class Calculator.
• Few minor code and test improvements.
