Anti-aliasing
Posted: 2014-04-07T05:41:59-07:00
Would it be feasible/easy to allow me to choose when NOT to use anti-aliasing?
Particularly, I would like to make a SHEAR operation on an image, *without* anti-aliasing. It seems the source code that says to be based on a paper, did not follow the paper that had an if test allowing the user to choose whether not to use anti-aliasing.
I am trying to work with B&W images that get terribly damaged when sheared with anti-aliasing (the default mode of IM).
I need to shear the image that will be "de-sheared" by another processing step, but the current IM shear process add lots of middle tones in the processing step, that ruin the next processing step in my use case.
Thanks
