You should really ask on the Ubuntu group there are folks there who know
considerably more than I do


I asked on Ubuntu, someone suggested to run, make clean, first
then I had to run the command that "make install" put out

fourier-0.4.3$ cp fourier /home/dale/.gimp-2.8/plug-ins

it works but the background looks around 50%, if I enlarge it I can see
some of the image

the reverse works too

I'm working off these tutorials
http://www.cs.unm.edu/~brayer/vision/fourier.html
http://homepages.inf.ed.ac.uk/rbf/HIPR2/fourier.htm
http://people.via.ecp.fr/~remi/soft/...n.php3#fourier

the last link has a Yuv transform from RGB, it installed right the same
way, know it is an approximation depending on what RGB, good enough for
me, for now







There are a lot of sharp people on the Linux groups (a few bad trolls too)
I'm glad you got it at least partially working.

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

That's one of the nice things about Linux.

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.

Default 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).

Just install it and do 'man convert' - describes fft and ift and, I
think, gives an example.

Ah so you are an old timer too.
I also was around in the punch card days and hated it.

Took FORTRAN -IV in 1968
hated those punch cards.
Ten years later I went back to school for some post-grad education and
was shocked to find punch cards still being used.

no, not that much of an old timer, I took punch cards around 1983, that
is what my community college had for basic ..., also took assembler and
still don't know what it is for

in 4 year school I took fortran and pascal, took a logic class and
thought that would help

at work I learned sas and matlab, c and OO

sas and matlab I had most programs written in a way I could edit them,
but I did write a program in matlab that calibrated a solitaire film
recorder for color negatives based on how they printed on paper, it
never really calibrated though nd I don't know if a multi-stage chemical
image process can much more than a grey card and leaving the rest to
editing (chemical or digital)

Oh my, hard to believe in 1983 they still were using punch cards.


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 bet you never used one like this.

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. :-(
