When I execute command convert from package imagemagick I get this
convert: unable to read font `(null)’ @ error/annotate.c/RenderFreetype/1127.
The same worked in raspbmc without any issue.
Any idea ?
Probably just a missing font package that needs installing.
We don’t bundle any console font packages by default - we just manually include a couple of console fonts for the blue update screen.
You would need to check the requirements for Imagemagick to know what apt package the fonts it needs are in and install that package. (I’m not familiar with Imagemagick)
