# Adobe Color Swatch
## Description
`swatch.py` is a Python 3 command line interface created to extract Color
Swatch data from `.aco` files and save them as a simple `.csv`. It can also
work in revers and generate a `.aco` file based on a `.csv` data file.
## Installation
Install from GitHub repository:
```
pip3 install git+https://github.com/kdybicz/adobe-color-swatch
```
## Usage
### Extract `.aco`
```
usage: swatch extract [-h] -i INPUT -o OUTPUT [-v]
Extract .aco input file to a .csv output file
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
input file
-o OUTPUT, --output OUTPUT
output file
-v, --verbose increase output verbosity
```
### Generate `.aco`
```
usage: swatch generate [-h] -i INPUT -o OUTPUT [-v]
generate .aco output file based on .csv input file
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
input file
-o OUTPUT, --output OUTPUT
output file
-v, --verbose increase output verbosity
```
## Specification
`.aco` file format parser and generator were created based on
[Adobe Color Swatch File Format Specification](https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/#50577411_pgfId-1055819).
Script is supporting both version 1 and 2 of the Color Swatch format.
`.csv` file is using custom format:
```
name,space_id,color
RGB Magenta 16-bit,0,#FF00FF
RGB Magenta 32-bit,0,#FFFF0000FFFF
CMYK Magenta 16-bit,2,#FF00FFFF
CMYK Magenta 32-bit,2,#FFFF0000FFFFFFFF
75% Gray,8,#1D4C
```
### Color space IDs
Supported color spaces
| ID | Name | Color information |
|:--:|:----------:|:-----------------------------------------------------------------------------------|
| 0 | RGB | Supports 16 and 32 bit channels, so accordingly 6 or 12 bytes of color information |
| 1 | HSB | Supports 16 and 32 bit channels, so accordingly 6 or 12 bytes of color information |
| 2 | CMYK | Supports 16 and 32 bit channels, so accordingly 8 or 16 bytes of color information |
| 8 | Grayscale | Supports 16 and 32 bit channel, so accordingly 2 or 4 bytes of color information |
NOT supported color spaces
| ID | Name |
|:--:|:------------------------:|
| 3 | Pantone matching system |
| 4 | Focoltone colour system |
| 5 | Trumatch color |
| 6 | Toyo 88 colorfinder 1050 |
| 7 | Lab |
| 10 | HKS colors |
## Validation
To validate that the `.aco` file generation is working properly I decided on
the following process:
* export few default Color Swatches from Adobe Photoshop 2022
* extract them to `.csv` files and make sure data in that files are matching
to what is in the Adobe Photoshop
* generate new `.aco` files from `.csv` acquired in the previous step
* compare original `.aco` files with ones regenerated from `.csv` using:
```
hexdump examples/utf.aco > utf.aco.hex
hexdump utf-new.aco > utf-new.aco.hex
diff utf.aco.hex utf-new.aco.hex -y
```
* import new `.aco` files into Adobe Photoshop and compare them with original
Swatches
### Notes
I'm aware that original `.aco` files contain some additional bytes at the end
of the files. Those bytes which will not be present in `.aco` files generated
by the script. These bytes might be related to
[Custom color spaces](https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/#50577411_28552),
which are not supported by this script.
Nevertheless I was able to successfully import generated `.aco` files back into
the Adobe Photoshop and use them in my work!
## Development
### Testing and linting
For all supported environments:
```
tox --parallel
```
**Note**: running tests for all supported Python versions require to have
Python interpreters for those versions to be installed.
For particular environment:
```
tox -e py39
```
For running tests in development environment:
```
tox --devenv venv -e py39
. venv/bin/activate
pytest
```
### Local installation
Install a project in editable mode:
```
pip3 install -e .
```
## Deployment
Building the packages:
```
./venv/bin/python setup.py sdist bdist_wheel
```
Checking if build packages are valid:
```
twine check dist/*
```
Uploading to pypi:
```
twine upload -r pypi dist/*
```
