20 April 2022: dvisvgm 2.13.4 has been released
  • 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.
27 February 2022: dvisvgm 2.13.3 has been released
  • 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.
23 February 2022: dvisvgm 2.13.2 has been released

This small release improves the clipping of embedded EPS/PDF graphics (issue #176).

26 January 2022: dvisvgm 2.13.1 has been released
  • 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.
20 January 2022: dvisvgm 2.13 has been released
  • 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.
23 November 2021: Information on PDF support as of Ghostscript 9.56.0

Ghostscript has introduced a completely rewritten implementation of its PDF interpreter, which is now implemented in C instead of PostScript. This has a lot of advantages besides the performance improvements. For third-party applications like dvisvgm, however, this change has significant impact on the functions that can be provided. dvisvgm relies on the possibility to overwrite PostScript and PDF operators in order to directly communicate with the interpreter. The nice thing about the current PostScript-based PDF interpreter is the fact that both PostScript and PDF code can be treated almost equally.

As of Ghostscript 9.56.0, this will no longer be possible, and as far as I can tell from the documentation, there is no way to replicate the current functionality. As a consequence, all PDF functionality currently available in dvisvgm will no longer work with the upcoming Ghostscript releases. Therefore, it will require the parallel installation of Ghostscript 9.55.0 or earlier. In the long run, I’ll probably have to drop PDF support since I don’t have the resources to implement a completely new PDF handler.

16 August 2021: dvisvgm 2.12 has been released
  • 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.
21 January 2021: dvisvgm 2.11.1 has been released

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.
