PyDye

PyDye is a python graphics library for OS X, powered by Apple's Quartz graphics layer.

Features

• Read and write common image formats (png, jpg, tif, bmp, etc)
• Bezier paths
• Gradients
• Affine transforms
• Pixel-level access for raster graphics
• "Pythonic" API

Why?

If your target platform is Mac OS X

PyDye "just works". It has no third-party dependencies. It uses OS X's native graphics layer, so you get high quality and performance out of the box

Here are a couple of short examples of what it looks like:

Drawing a circle

with Image(800, 600) as img:
    Oval(center=(400, 300), radius=100).fill(color=RGB(1, 0, 0))
img.save('~/Pictures/Circle.png')

Vignetting an image

overlay = Gradient(start=RGBA(0, 0, 0, 0), stop=RGBA(0, 0, 0, 0.9))
with Image(path='~/Pictures/blueSky.jpg') as img:
    overlay.draw_radial_in_rect(img.bounds())
img.preview()

If your target platform is not Mac OS X

See Why Not.

Why Not?

• It's not cross-platform - it only works on Mac OS X.
• It's still in alpha.

Requirements

• Mac OS X 10.7 or newer

Dependencies already bundled with OS X

• Python 2.7
• PyObjC
