Encode bytes of a file to PNG format:
Colorpress::encode('file.txt') # creates file.txt.png, minimum width 50 px
Colorpress::encode('file.txt', 'out.png', min_width=100) # creates out.png, minimum width 100 pxDecode bytes of a PNG back into character data:
Colorpress::decode('file.txt.png') # creates file.txt, deletes file.txt.png
Colorpress::decode('file.txt.png', cleanup=false) # creates file.txt, keeps file.txt.png
Colorpress::decode('out.png', 'original.txt') # creates original.txt, deletes out.pngDocumentation for all methods can be generated by running yard doc in a development environment.
