Graphic Slicing with The Gimp?

Ivo asks: "I'm a webdeveloper working almost exclusively in Linux. But I currently still use Windows to use Adobe's ImageReady, to splice up the designs that we get from our webdesign partners. Usually, if someone asks 'can I do Adobe Photoshop stuff on Linux', the answer is of course, Gimp. Gimp rules. No doubt about that, and I use it all the time. But I miss the features that ImageReady has, like automatic generation of a lot of small images and buttons for a website, including mouseover and mouseoff variants. Doing that manually in Gimp or Photoshop takes hours. Is there a program for Linux, or even better a plugin for Gimp, that does what ImageReady does?" How difficult would something like this be to do using Script-Fu?

try python

[DrSkwid]

and the PIL module

you can even do it interactively

python is cross platform too so your scripts won't be wasted if/wehn you move platforms

I use it for generating thumbnails and <img> tags and whatever

Re:try python

quick cut and paste from the pythonware site

Example: Create JPEG Thumbnails
import os, sys
import Image

for infile in sys.argv[1:]:
outfile = os.path.splitext(infile)[0] + "-thumb.jpg"
if infile != outfile:
try:
im = Image.open(infile)
im.thumbnail((128, 128))
im.save(outfile, "JPEG")
except IOError:
print "cannot create thumbnail for", infile

try checking our Gimp Script-fu

Try checking out Gimp Script-fu or Gimp plugins.

Or check to see if you have perl-o-tine installed. From the image, right click, filters/web/perl-o-tine... It is included in my SuSE install of gimp 1.2.2, bymmv. Perl-o-tine will split an image into a set of squares for you, I don't really know how to use guides, so at the moment I can only create nxn grids, however, each box can be of an arbitrary size. Doesn't really help with rollovers though.

The rollover plugin may help more here, but I have never used it, so don't know how it works.

Good luck!

Script-Fu yes, and Perl-Fu...

Script-Fu is good for zillions of things, like automatical creation of whatever your heart desires.

Of course, it's based on rather "limited" Scheme implementation. I'd recommend Perl-Fu - everything Script-Fu can do and more, in a vastly easier-to-debug environment.

Neither of the languages are too hard, but Perl-Fu will be my favorite from now on.

I have some example scripts in the web, too. In case anyone cares. Not much of Perl yet, but more than enough Scheme to confuse anyone =)
