Filigram-rs

This library is a convenient wrapper to watermark image files in a folder, recursively.

Input folder is copied entirely, applying watermark on image files, depending on some exclusion/inclusion rules. If a file is excluded from watermarking, it is simply copied to destination without any change.

Watermarking process:

• watermark text (customizable) is applied
• image is resized to a fixed size of 500x500
• process is multithreaded using rayon crate
• recopy source image Exif metadata and ICC profile to output image
