Images are not rendered. Imagemagick issue

[fkgruber]

I installed emacs 27 with brew install emacs-plus@27 --with-modern-orange-icon --with-xwidgets

I can't open any images files. They are blank. Images embedded on orgmode are also blank.

the Message buffer gives error:

ImageMagick error: UnableToOpenFile '/var/folders/_w/dcs87wy950b8bsf1ftp8w39nbjnl50/T/magick-CvuAudv07yXwfleoAGagJBzGdr4EJfd3': No such file or directory @ error/constitute.c/ReadImage/612

Oh my. In case you installed Emacs+ some time ago and then did run brew upgrade, you might need to reinstall Emacs+, because ImageMagick was updated (and for some reasonbrew didn't enforce recompilation of Emacs+ :shrug: ). And by reinstall I mean brew uninstall emacs-plus followed by brew install emacs-plus [your-options]. Do not use brew reinstall command.

[fkgruber]

Ok I tried:

brew uninstall emacs-plus
brew upgrade
brew install emacs-plus@27 --with-modern-orange-icon --with-xwidgets

PNG and JPG are working now but SVG still gives problem: Opening a SVG I get: ImageMagick error: must specify image size `/var/folders/_w/dcs87wy950b8bsf1ftp8w39nbjnl50/T/magick-NcZBgepTosekSswYPrRmyIaVxR3BuPQi' @ error/mvg.c/ReadMVGImage/186

[fkgruber]

This seems to be related to. imagemagick:

convert tst.svg tst.pdf
convert: must specify image size `/var/folders/_w/dcs87wy950b8bsf1ftp8w39nbjnl50/T/magick-GsdZ3V7-4U9uNBbt0s-jEqxXyRsgdAuC' @ error/mvg.c/ReadMVGImage/186.
convert: no images defined `tst.pdf' @ error/convert.c/ConvertImageCommand/3322.

any idea what my be causing this?

[fkgruber]

This works: convert -size 568x604 tst.svg tst.pdf

so it seems that the current version of convert requires you to specify the image size for svg files.

[fkgruber]

It is very strange the list of delegate clearly shows that it is using rsvg-convert to do the transformation

fred$ convert -list delegate |grep svg

        cdr =>          "@UniconvertorDelegate@' '%i' '%o.svg'; /bin/mv '%o.svg' '%o"
        cgm =>          "@UniconvertorDelegate@' '%i' '%o.svg'; /bin/mv '%o.svg' '%o"
        dot =>          "dot' -Tsvg '%i' -o '%o"
        dxf =>          "@UniconvertorDelegate@' '%i' '%o.svg'; /bin/mv '%o.svg' '%o"
        fig =>          "@UniconvertorDelegate@' '%i' '%o.svg'; /bin/mv '%o.svg' '%o"
        pnm<= trace     "potrace' --svg --output '%o' '%i"
        svg =>          "rsvg-convert' -o '%o' '%i"

and this works if I call it directly rsvg-convert -o tst2.png tst.svg

[fkgruber]

After further research it seems that some svgs work while other don't. SVGs that are missing the viewport do not work. The weird thing is that when I tried emacs-mac homebrew the same svg works fine. I'm not sure how they did it. FKG

[d12frosted]

@fkgruber nice investigation 🕵️ Could you please send me an example SVG so I can check this. I do preview images in Emacs, but SVG support was always clunky, so I don't use it for that.

The weird thing is that when I tried emacs-mac homebrew the same svg works fine. I'm not sure how they did it.

They are using different renderer, which I guess tolerates stuff like this.

[fkgruber]

I'm interested in rendering SVG to include handwritting content to my org-roam notes: handwriting

I'm attaching 2 svgs. The Yin_yang.svg should work fine. I then removed the viewport from it and saved it as yinyang2.svg. That one does not work for me. Can you replicate that behavior?

svgimage.zip

[orgtre]

I can replicate this issue with Emacs installed via brew install emacs-plus@28: Yin_yang.svg displays fine, while yinyang2.svg doesn't display. With Emacs installed via brew install emacs-mac both display but only the lower right quarter of yinyang2.svg is shown (as is the case in macOS quicklook).
