Description:

propertiesimage 0.0.1

Why
properties gives structure (and documentation!) to the properties you use in your
classes. properties-image extends this to include image files.

Scope
The properties package allows you to create strongly typed objects in a
consistent way. This allows you to hook into notifications and other libraries.
The properties-image package contains additional image file properties with
external dependencies not included in properties.

Goals

Provide supplementary Property classes to the properties module
Allow dependency-heavy classes to be installed separately

Alternatives
Alternatives to properties:

traits is used by Enthought
traitlets is used in the Jupyter project
mypy and PEP0484 which document typing but do not include coercion or notifications

Other image libraries:

pypng for PNG encoding/decoding
Pillow a fork of PIL
scikit-image for image processing

Connections

properties
steno3d for the client API

Installation
To install the repository, ensure that you have
pip installed and run:
pip install properties_image
For the development version:
git clone https://github.com/3ptscience/properties-image.git
cd properties-image
pip install -e .

Examples
To include an image property, import properties and properties_image.
Then the image property classes will be in the ext module. For additional examples,
see properties.
import properties
import properties_image
class NamedImage(properties.HasProperties):
name = properties.String('Name of the image')
image = properties.ext.ImagePNG('The image')
