It is most likely something regarding your installation of ImageMacick. How did you install it? In Ubuntu I recommend sudo apt install inkscape as inkscape already brings it with the best svg to png conversor, but I am not familiar with MX Linux.

Also it would be helpful if you run convert debian.svg debian.png and see what it outputs (you can get debian.svg from here).

Thanks for your reply.
ImageMagick already installed by default in my MX but not for inkscape. so I installed it from synaptic.
should I reinstall imagemagick?

and the convert command that you suggest, there is no error output after converting. the exit code is 0

sorry for my english

[mateosss]

Okay let's try something else.
Below should be a command very similar to the one Matter issues when converting svg to png.
Try running it as you did before for debian.svg. It will probably throw the same error you got before. Remove flags one by one until you find which one is the problem.

convert -trim -scale 36x36 -extent 72x72 -gravity center \
-define png:color-type=6 -background none -colorspace sRGB \
-channel RGB -threshold -1 -density 300 -fill \#ffffff +opaque none \
debian.svg debian.png

(Note: If the command does not give you errors, try running it with sudo at the start, as Matter runs it as superuser)

You could as well try reinstalling imagemagick, that may help.

I have the same problem but I can't find the right command to be able to generate icons. 🙁
It would be nice to have a fix.

[mateosss]

@Bricklou Are you on MX Linux 19.2 as well?

[Bricklou]

I use archlinux with the latests updates

[Bricklou]

Material Icons are rendered empty and my custom SVG just show white

[mateosss]

Okay, I'm unable right now to address this because of a lack of time, any help debugging the issue is welcomed.
Eventually the idea is to bundle the svg conversor directly into Matter to avoid these kind of problems with ImageMagick in the future. Stay tuned.

[Bricklou]

Can we still use PNG files instead of SVG one ?

[mateosss]

Yes you could drop the PNGs inside /boot/grub/themes/Matter/icons, they should have their proper name (i.e. if you specified icon name microsoft-windows then the icon you place should be /boot/grub/themes/Matter/icons/microsoft-windows.png)

[Bricklou]

I found why the script bug, it seem that the fill and background argument are applied on the document and not the path of SVG files. But I don't know how to fix it. 😕

Same issue on Void Linux with latest updates. Latest ImageMagick and Inkscape installed.
