A Ruby command-line app which which transforms Open Cross Stitch (.oxs) patterns into "shadow knitting" patterns.

This project requires Ruby 3.4.1.

$ git clone git@github.com:nahiluhmot/illusion_patterns
$ cd ./illusion_patterns/
$ bundle install

To generate a shadow knitting pattern from your pattern, run:

$ ./bin/illusion_patterns path/to/your/pattern.oxs 0 29 up

Breakdown:

• ./bin/illusion_patterns - the executable provided by this application
• path/to/your/pattern.oxs - an Open Cross Stitch file which contains your pattern
• 0 - the palette index of the background color of your pattern; this will be used for the "light" shadow knitting stripes
• 29 - the palette index of the "dark" shadow knitting stripes; this color should not be used elsewhere in your pattern
• up - the direction from which the pattern should be visible; down is also valid
