Mikko Koppanen's Blog:
ImagickPixelIterator is not read-only after all...
November 15, 2007 @ 09:38:00

Mikko Koppanen is back with a tip for users of the ImagickPixelIterator functionality of Imagick - it's not read-only after all.

A few days ago I got a help request from a user: "How do you change pixel color during the iteration with ImagickPixelIterator". My initial response was that ImagickPixelIterator is read-only. Well, I have to admit I was wrong. After searching trough ImageMagick docs I stumbled across an example and noticed that PixelIterator (and therefor ImagickPixelIterator) is not read-only after all.

He illustrates with a code example, one showing how to make the object from an image and how to update every second pixel to be black. Source and result images are also included.
