# 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.

```bash
# Build and run using docker
./pixsaw.sh
```

## Installing

Requires:

* [Pillow](http://github.com/python-imaging/Pillow)

Install with pip in editable mode for developing and use virtualenv to isolate
python dependencies::

```bash
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

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

The output (combined into one file with glue to better show it):

## 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"
