Cut a picture into pieces by cutting along pixel lines
Cuts an image up into multiple pieces by following pixel lines that contrast with targeted piece color. Most pixels are kept in the process since very fine saw blades are used.
Try out by running the
pixsaw.sh script that will prompt for necessary options
and run pixsaw inside a docker container. It will use the files in the examples
directory by default.
# Build and run using docker ./pixsaw.sh
Install with pip in editable mode for developing and use virtualenv to isolate python dependencies::
python3 -m venv .venv source .venv/bin/activate pip install -e .
pixsaw script will show some help. It basically needs a
path to a directory to store the generated files, an image that shows where to
cut, and the image that should be cut into pieces.
mkdir tmp-small-puzzle-example pixsaw --dir tmp-small-puzzle-example --lines examples/small-puzzle-lines.png examples/320px-White_Spoon_Osteospermum.jpg
