I have installed ImageMagick-6.3.7-2 on RHEL4.
But I got error when I used Extent method as follows:
Anyone please tell me how to solve it, or workarounds.
I just want to put an image into fixed size or frame:
ex) original image is 480x320px,
then resize to 120x80,
spread 20px-height white background on top and bottom,
then finally 120x120px.

Its possible that Extent() is not supported for ImageMagick 6.3.7. You can emulate Extent() by creating a canvas and compositing your image on top of it or try upgrading your release of ImageMagick.
