I don't know if any more development is being done on F.T. for GIMP Brings back some memories though. Back in the 70's one of my friends from engineering school ended up at GE and he was on the design team for the FFT (Fast Fourier Transform) used in the early CAT scanners. I might take a look at the code and hack at it, I think it must be the fast version, might also hack at Gimp plug-in API, Gimp scripts and Gimp python thanks -- Dale |

Though I am not a coder, I at least made a few simple shell scripts so I can change the brightness of my screen with one click. I have different settings for reading text vs photo editing etc. |

fourier plug-in for gimp

having troubling with make and make install of the fourier transform plug-in for gimp http://chidge.net/?m=stuff&o=howtos&p=fft supposed to do forward and reverse the make error I get is make: Nothing to be done for `all'. if I (make install) after the make error, there is no error and it creates a binary, but the filers don't show up under filters/generic like the website above says the binary is call fourier, if I try to run it I get the error bash: ./fourier: cannot execute binary file: Exec format error there is something other things called --install-bin and gimptool-2.0, but if I try to execute them, there are errors do I have to move the binary somewhere? I think I have all the libraries, there are no errors that libraries are needed I am using this version of Ubuntu Linux Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty and GIMP 2.8.10 I'll be googling around in the mean time... FWIW you should be able to accomplish that with the ImageMagick - convert command - there is an option for fft and one for ift (inverse fft). |

Back in 1968 when I took my first class I was shocked even then at how antiquated things were. There was /one/ terminal on campus but it was reserved for the upperclassmen. No CRT...it was a teletype machine. The only way I learned anything at all was in 1982 when I bought a Ti-99/4 and learned BASIC. Since I knew FORTRAN, there was nothing to it and since I got instant feedback I learned more in a few weeks than I did in years of college. |

I also was around in the punch card days and hated it. I bet you never used one like this. http://upload.wikimedia.org/wikipedi...Card_Punch.jpg You had to play chords for most characters. The feet, plywood base and the tray for collecting chads are a later addition. Took FORTRAN -IV in 1968 Fortran 2 in 1961. :-( hated those punch cards.
