I was about to integrate Github Actions to one of my pet projects but the tests failed with:
convert-im6.q16: unable to read font `helvetica' @ error/annotate.c/RenderFreetype/1338.
In the project i was using ImageMagick
convert command directly as sub process and obviously some fonts where missing.
Makes sense because i used convert to add text to an image.
So how do i add missing fonts?
First lets see what fonts are installed, i tried this locally:
Code language: PHP (php)
convert -list font
For Helvetica it showed:
Font: Helvetica family: Helvetica style: Normal stretch: Normal weight: 400 glyphs: /usr/share/fonts/type1/gsfonts/n019003l.pfb
In Github Actions there were no such path, so it seems that gsfonts was missing.
And indeed gsfonts needs to be added, so lets install it:
- name: 'install deps' run: "sudo apt install -y libfreetype6-dev gsfonts libmagickwand-dev imagemagick"
Now Github actions pass, nice.
