A quick search on the web shows that this has been an issue for some people, including myself, who wanted to perform colour quantisation using PythonMagick. I could not find any information online explaining why the enumeration was not provided as part of the interface.
In the hope it was just an omission and that I haven't missed some deeper meaning, here's a patch which exposes that enum in PythonMagick. I have perform limited testing of the functionality in Python and all seems well.
Example usage:
Code: Select all
import PythonMagick as pm
img = pm.Image()
img.read('/tmp/test.png')
img.quantizeColorSpace(pm.ColorspaceType.YUVColorspace)
img.quantizeColors(64)
img.quantize()
Code: Select all
