Examples

Recover fonts from 2 .ass files and save them in the current folder

fontCollector -i "file1.ass" "file2.ass"

Take all the .ass files from the current folder and save the font in the current folder

fontCollector -i .

Mux font from .ass file into an mkv

fontCollector -i "file1.ass" -mkv "example.mkv" -mkvpropedit "C:\Program Files\MKVToolNix\mkvpropedit.exe"

Mux the font from the .ass file into an mkv and delete the currently attached fonts.

fontCollector -i "file1.ass" -mkv "example.mkv" -mkvpropedit "C:\Program Files\MKVToolNix\mkvpropedit.exe" -d

Variable Font

Since Libass does not support variable font, this tool will automatically generate a OpenType Font Collection. The generated collection is designed to simulate how VSFilter/GDI handles variable font.

Myaamori-Aegisub-Scripts Without this tool, I probably could never have created the fontCollector. I got a lot of inspiration from his work.
PyonFX I inspired myself from his setup.py to create mine.
