I'm generating .svg files with mahe4ht and dvisvgm. The .svg is generated but contains text at the beginning regarding the use of option -dNEWPDF:

The old, written in PostScript, PDF interpreter has been removed entirely.
You should cease using -dNEWDPF as it has no effect n
<?xml version='1.0' encoding='UTF-8'?>
<!-- This file was generated by dvisvgm 3.0.3 --> ...

If I remove the text till <?xml... the graphic is shown properly in the browser.

Question: How do I get rid of the text during processing of the files?

I use MacTeX 2023 (TeX Live 2023) on MacOS Monterey with recent updates. Maybe editing some scripts is necessary but I don't know which one(s).

  • The GS option -dNEWPDF was only removed after the release of dvisvgm 3.0.3. As this version still uses the option, the current versions of Ghostscript print an error message -- unfortunately to stdout which therefore might end up in the SVG file depending on the usage of dvisvgm. As of version 3.1.1, dvisvgm omits -dNEWPDF for GS versions >= 10.0.2.

I know about this issue and fixed that in TeX4ht sources in December. The update is included in TeX Live, so I would expect that it is MacTeX too, but maybe it takes more time in this distro.

Anyway, the dvisvgm_hashes doesn't suffer from this issue. Moreover, it significantly speeds up the compilation, so if you have a lot of SVG files, the compilation will be much faster. Try this command:

$ make4ht -f html5+dvisvgm_hashes filename.tex

Thank you Martin and Michal, I updated my TeX Live using the TeX Live Utility and that fixed this issue.
