Multiprocessing support #43

Closed FriedrichFroebel closed 2 years ago

FriedrichFroebel commented 2 years ago

I recently used ocrodjvu to add text layers to different DJVU files using Tesseract, with each file having 400-900 pages. Unfortunately, only one thread and less than one 1 GB of RAM has been used, making it quite slow and taking quite some time (example: 3 hours for nearly 900 pages), while the system load has been quite small even with my rather old hardware.

For this reason I would like to see some real multiprocessing support which speeds up the execution.

Nevermind, I must have overseen the -j option which seems to already support this.
