This is a small Python3 module to import Designaknit
.stp
and .pat
knitting pattern files as images. The code to convert .stp
files
was originally written in Java by Guntram Blohm in response to a stackexchange question
(https://reverseengineering.stackexchange.com/questions/12235/reading-stp-designaknit-stitch-pattern-files-ii/12239#12239).
As .stp
files are somewhat encrypted, it's not easily possible to read or convert them
to anything else. The original intention of this software was to show how to read and
decrypt those files. The older .pat
file format is similar but without any encryption.
The program reads two kinds of data from the files:
- color pattern
- color palette
Two further types of information are ignored, for the current purposes:
- stitch pattern
- stitch types
The two public methods of the Importer class are pat2im()
and stp2im()
. They take as
their argument a filename and return a PIL.Image
object.
