pixsaw 0.5.0

Cut a picture into pieces by cutting along pixel lines

Pixsaw

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

Installing

Requires:

• Pillow

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 .

Usage

Running the 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.

Example

mkdir tmp-small-puzzle-example
pixsaw --dir tmp-small-puzzle-example --lines examples/small-puzzle-lines.png examples/320px-White_Spoon_Osteospermum.jpg

Maintenance

Where possible, an upkeep comment has been added to various parts of the source code. These are known areas that will require updates over time to reduce software rot. The upkeep comment follows this pattern to make it easier for commands like grep to find these comments.

Example UPKEEP comment has at least a 'due:' or 'label:' or 'interval:' value surrounded by double quotes (").

Example-> # UPKEEP due: "2022-12-14" label: "an example upkeep label" interval: "+4 months"
