Re: Minimum GS version
The EPS files have some tricks to keep sizes small (load font files directly from the FS), which requires -dNOSAFER, and makes them more fiddly. If you are trying to get up to speed with regression testing, you could try running the whole thing (baseline and test) with -dbackend=cairo which produces PNG files directly.

Uh. I wonder if the resulting pdf, notwithstanding the directions to embed the fonts, also requires something like nosafer to work...

Re: Minimum GS version
I'm using the same options that gv uses, nosafer and all, and gv displays the file just fine. I've not fiddled with it enough to make gs DRIVER=display work, because WSL2 and that driver don't seem to be on good terms. But I'll spend some time on that today. Because I'm still experimenting with things, I'd rather have under control how to go from a vector representation to a raster (I'dlike to investigatethe effects of resolution and AA settings, for example), can I use Cairo in pdf mode?

Re: Minimum GS version
Ok so, I looked in the PDF and I saw I got a partial improvement using -dEPSCrop, now I get a pdf that gv will open (but interestingly not okular, for some reason) This is weird.

You can use Cairo if you add LOCAL_LILYPOND_FLAGS=-dbackend=cairo local.make, and apply the following commit e48daf754a323eca0c5b15f8677d4c9574c98ad4 (HEAD -> top) Author: Han-Wen Nienhuys Date: Sun Sep 29 10:56:46 2024 +0200 pdf diff --git a/make/lysdoc-targets.make b/make/lysdoc-targets.make index 453b449575..f425c9de32 100644 --- a/make/lysdoc-targets.make +++ b/make/lysdoc-targets.make @@ -19,7 +19,7 @@ lysdoc-test: # Removing it works around incomplete dependencies. rm -f $(outdir)/collated-files.texi time $(MAKE) LILYPOND_BOOK_LILYPOND_FLAGS=" \ --dseparate-page-formats=ps $(LILYPOND_JOBS) -dseparate-log-files \ +-dseparate-page-formats=ps,pdf,png $(LILYPOND_JOBS) -dseparate-log-files \ -ddeterministic \ -dinclude-eps-fonts -dgs-load-fonts --header=texidoc \ -dcheck-internal-types \ @@ -27,7 +27,7 @@ lysdoc-test: $(LOCAL_LILYPOND_FLAGS)" \ LILYPOND_BOOK_WARN= \ LYS_OUTPUT_DIR=$(top-build-dir)/out/lybook-testdb \ - $(outdir)/collated-files.html + $(outdir)/collated-files.pdf # Later testing will find fonts via this link.

Re: Minimum GS version
Brilliant. Now that I got EPSCrop going, I am able to make my own rasters using mupdf, and it's working well. eps -> pdf takes ~ 70ms pdf -> numpy array ~ 5ms (a 300dpi raster of 221x1884 pxl, I have run this with 8x8 aa and aa disabled and I got the same speed) SIFT feature detection -> 500ms ORB feature detector -> 250ms corner feature detector -> 80ms I suspect I can stand up gs once and make a giant pdf with one cropped page per input EPS, which is likely to improve the overall efficiency of the initial rasterization process a fair bit, but until I figure out whether this feature-based comparison concept even has merit, all that is secondary. One way or the other now I'm in a place where I can actually work :-) L On Sun, Sep 29, 2024 at 11:13 AM Han-Wen Nienhuys wrote: > On Sun, Sep 29, 2024 at 9:32 AM Luca Fascione > wrote: > > > > I'm using the same options that gv uses, nosafer and all, and gv > displays the file just fine.

LilyPond 2.25.20
We are happy to announce the release of LilyPond 2.25.20. This is termed a development release, but these are usually reliable for testing new features and recent bug fixes. However, if you require stability, we recommend using version 2.24.4, the current stable release.
