PythonMagick::ColorspaceType
Posted: 2014-03-17T06:30:40-07:00
The MagickCore::ColorspaceType enum is not implemented in PythonMagick 0.9.9.
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:
