Hi there,
Your project is very simple. Will use ImageMagick and PIL libraries. I am also expert in regex, your project probably will need. For sure will support batch process. And support for local languages is no problem; it is handled automatically. Your app will have GUI too + multi-threaded; and will work completely offline and standalone.
Best regards,
Ishaq
