[magick-users] Distort variables in a function

[linda fasciano]

How do I write the Perspective variables so that it can be made into a function where all I would have to change are the size variables and have it automatically adjust to any size?  I tried looking at the -fx codes but everything I tried did not work.  Also is there a way to discard the temporary images used in the montage.
