I have installed ImageMagick 6.5.8 from source on Ubuntu 8.10 followed by the instructions listed here
> tar xvfz ImageMagick.tar.gz > cd ImageMagick-6.5.8 > ./configure > make > sudo make install
Installation was successful but when I try to use 'liquid-rescale' operator it showed:
> convert source.png -liquid-rescale 500x500 output.png convert: delegate library support not built-in `source.png' (LQR) @ resize.c/LiquidRescaleImage/1550.
Looks like it was compiled without liquid-rescale support.
I wonder how to turn on liquid-rescale when installing ImageMagick from source.
Thanks in advance.
