I wanted to add fonts for Titler effect, for the titles. As I use the Cinelerra AppImage, it was great to see the workaround for adding fonts detailed in the manual.
CinelerraGG_Manual/FAQ_Known_Problems_Workarou.html#cha:faq_problems_workarounds
and here
**CinelerraGG_Manual/Managing_AppImage.html#sub:managing_appimage **
When I went to re-compress or re-create the AppImage after adding several TTF into /squashfs-root/usr/bin/plugins/fonts, the commandline
linuxdeploy-x86_64.AppImage --appdir squashfs-root --output appimagefailed to create a new AppImage. Many warnings but no result. The messages are at pastebin for a short time.
As a workaround, I can see that the expanded or uncompressed AppImage can be run as is. I have not tried this yet. So I mention this here simply as an observation. In the next days I will hope to run the expanded AppImage as is, and be able to use the added TTF. I will report back on that success.
