I just had a look at the two plug-ins for fun of it and they
doing part of the problem differently, which means that the perl
program looks more complicated than necessarry. The
scheme plugin uses the plug-in plug-in-colors-channel-mixer to
do the actual color mixing, whereas the perl plug-in accesses the
pixels itself. Accessing pixels always gets dirty, because of the tile
based approach of gimp. Actually, I think that Marc Lehmann's use
of PDL for the job is very elegant. But I'm sure that it can be
confusing to have to learn another huge sublanguage (which PDL
is).
the perl plug-ins were/are wonderful. i use the heck out of some of
them. i ask only not to have to *read* them anymore. something about
that language makes this plug-in a sad read. i hope i did not say not
to write them. it is the reading part that i cannot endure.
i have done everything that is humanly possible to get perl ported to
gimp-1.3 and the plug-ins as well. okay, short of begging a scary hero.
it is not my fault that it was easier to find people to rewrite them in
other script. how about making a splash screen contest so i could show
the splash that me and bit and cameron made?
i can't read it. and when i can, it can be chilling.
So if you want to compare syntax, please compare the same approach
in the different languages.
I'm curious, does the python plug-in allow you to access the
pixels?
Dov, i have no idea. i just know that i am able to use the little
pieces. it doesn't allow my imagination to run away with me. i can
start working on a plug-in (armed with a lot of little pieces located
in two directories on my computer), get distracted, go back to it in a
few weeks and still be able to figure out what was going on.
okay, in truth, i got stuck at the same place with both scripting
languages on my cross-stitch plug-in. the point where the xpm gets
read in and handled. when i get the chance, i think i can actually
handle this with python, eventually and with a lot of help; but. i don't
think i will ever be able to sort through it with perl. and i am truly
humbled by those who can.
good heavens, please don't stop writing perl!

Debugging: you might try firing up the script-fu console in the GIMP
and testing code snippets there. I've found this to work fairly well.

Eeek!
Jeff, just say no!
all three versions of gimp i have used, 1.0 1.2 and 1.3 have a nifty
python plug-in complete with browser and console as well.
today i read two plug-ins for red-eye removal. the script-fu just
looked like gibberish:
http://cs.uhh.hawaii.edu/~jeschke/photography/articles/gimp/RedEye2/red-eye.scm
this one. this was the saddest thing i ever read. i never want to read
something this sad again. please. it is not the authors fault. it is
not the fault of the person who ported gimp to it. nor the gtk guy that
did it. not the original authors of this scripting language either. i
don't know why it is so sad. you have to stop making me try to read this.
mercy!

i would like to read it written in python. it is direct and the modular
part is starting to make sense to me. it makes me angry (okay
frustrated) not sad. that is better. please someone write this in
python quick so we can compare before i forget!
