Fourier Transforms

Post by adelina »

hi,I am using Image magick-6.7.1-Q16 for Windows Binary Release, and I want to use the Fourier Transforms and i can't. For ex :
"convert ima1.png -colorspace gray miff:- | im_profile -s im1m.png"
and it shows me this error:
"im_profile" is not a recongnized as an internal or external comand,operable program or bacth file"

im_profile is a bash unix script written by Anthony and can be found at http://www.imagemagick.org/Usage/scripts/

Most of the above, except the first reference is geared towards using FFT in a Linux/Mac environment due to the bash shell scripting. For windows users, see http://www.imagemagick.org/Usage/windows/. However, the basis IM FFT functions (-fft, -ift, +fft, +ift and other IM functions) should work just fine under windows. It is the additional shell scripting and such that will be the issues.

If you want to run everthing as in the examples, then you should probably install the unix environment for windows, Cygwin.
