See http://www.imagemagick.org/Usage/distorts/#perspective
Briefly, perspective transformation is *not* an affine transformation.
Affine transformations include only scaling, shearing, rotating and
translating, none of which can alter the ratio of lengths in the way
that perspective requires. Therefore the -affine option isn't going
to cut it. You have to do heavier lifting using the -fx option, using
numbers calculated using the perl script on that page (or a similar
method).
Hmms, too slow for a CGI script. I need to get another tool to do this :(
