How to extract images from .pat file?

Have a example.pat file with a photoshop patterns, but i use Krita on Ubuntu, and need extract the patterns from .pat file to krita compatible file patterns.

How to extract all images from .pat file to multiple png files without using windows or photoshop application?, have a application to extract files from a single file by binary header like as png, jpg, etc?. I find forensic apps, but not found.

Thanks.
