Hi,

I am still working on the projective transformation of images, see
http://www.cit.gu.edu.au/~anthony/graphics/imagick6/distorts/#perspective

One of the problems I meet is that if I want to rectify a complete perspective photograph, the output image usually has not the same size as the input image. By default, the -fx operator creates an output image of the same size as the input image.

At the moment, I solve this problem by calculating the dimensions of the output image and enlarging the input image as needed by adding a white border.

Is there a more direct way to handle this?
