If you don't specify a font what one is used by default?

If you don't specify a font what one is used by default?

I think it relies on the system default font, but am not 100% sure of that. In the font family documentation https://imagemagick.org/script/command- ... php#family it seems to say it is Arial. But that only works if you have arial on your system. You do not seem to have any default set. I know little about Linux, but on my Mac, it is Arial.

One can find the default, if it is set by adding -debug annotate to your command:

Code: Select all

convert -debug annotate -background white -pointsize 20 -gravity center label:"test" null:

But why would you rely upon some default font? You should always provide the font you want by name if it is set in your type.xml file or by path to the font file. -font arial or -font /path/to/arial.ttf

See https://imagemagick.org/script/resources.php for the type.xml file.

See https://imagemagick.org/Usage/scripts/imagick_type_gen for a script to load all the appropriate fonts on your system into the type.xml file so you can reference them by name.

You can also specify MAGICK_FONT_PATH. See https://imagemagick.org/script/resources.php
