Why don't you write yourself a simple script that does steps 2 to 5 and only asks for the filename? Should be doable in a few lines of Python or Script-Fu.

Ok, that seems a bit messed up - installing libgimp-dev should be painless, but maybe there are some odd version mismatches or whatever.

You're probably right in not trying to install libgimp-dev if it has these consequences. Maybe ask in a forum for your distribution what should be done there...

According to documentation gimptool is required for adding gimp scripts.

It is not required, it has a convenience function for script-fu scripts. You can as well just copy your script-fu-script to ~/.gimp-2.x/scripts/ .

Have fun, Simon

I use debian. I do not have gimptool installed, which is part of libgimp2.0-dev, which is not installed on my system.

You don't need gimptool and you don't need the development package installed. The whole point of a scripting language is that you can write one without installing any additional tools. All you need is a text editor.

According to documentation gimptool is required for adding gimp scripts.

That is bogus. Can you tell us where this written so that it can be fixed?

Hi,

I try to write a gimp-fu script to save the current image as a gif. I found a sample script on the web that seems to fit: -------------------------------------------------------- (define (script-fu-glogo-simple2 srcimg dummy filename) (let*
(
(img2 (car (gimp-channel-ops-duplicate srcimg))) (img16 (car (gimp-channel-ops-duplicate srcimg))) (img224 (car (gimp-channel-ops-duplicate srcimg))) (drawa (car (gimp-image-active-drawable srcimg))) (drcol (car (gimp-drawable-color drawa))) )
;
; Set names to the images (debug-info) ;
(gimp-image-set-filename img2 "glogo-bw") (gimp-image-set-filename img16 "glogo-16") (gimp-image-set-filename img224 "glogo-224") ;
; Resize (i.e. scale) them all
;
(gimp-image-scale img2 80 80)
(gimp-image-scale img16 80 80)
(gimp-image-scale img224 80 80)
;
; Convert them to RGB if they are not ;
(if (= drcol 0)
(begin
(gimp-convert-rgb img2)
(gimp-convert-rgb img16)
(gimp-convert-rgb img224)
)
)
;
; Flatten it
;
(gimp-image-flatten img2)
(gimp-image-flatten img16)
(gimp-image-flatten img224)
;
; Now change the palletes
;
(gimp-convert-indexed-palette img2 1 3 0 "") (gimp-convert-indexed-palette img16 1 0 16 "") (gimp-convert-indexed-palette img224 1 0 224 "") ;
; Save it as gifs (not needed anymore) ;
; (file-gif-save 1 img2 (car (gimp-image-active-drawable img2)) ; "/tmp/x-2.gif" "/tmp/x-2.gif" 0 0 0 0) ; (file-gif-save 1 img16 (car (gimp-image-active-drawable img16)) ; "/tmp/x-16.gif" "/tmp/x-16.gif" 0 0 0 0) ; (file-gif-save 1 img224 (car (gimp-image-active-drawable img224)) ; "/tmp/x-224.gif" "/tmp/x-224.gif" 0 0 0 0) ;
; Save it as linux boot logo
;
; (gimp-message (string-append "Debug-Info: img2=" (number->string img2 10) ; " img16=" (number->string img16 10) ; " img224=" (number->string img224 10))) (extension-linux-logo 1 filename

;
(gimp-image-delete img2)
(gimp-image-delete img16)
(gimp-image-delete img224)
)
)

(script-fu-register "script-fu-glogo-simple2" "/Script-Fu/Save as Linux Boot Logo2" "Saves any given image as Linux Boot Logo2" "Clifford Wolf"

)
-------------------------------------------------------- (In the script file-gif-save is commented out, it fails at refresh, if not commented out)

However when I run this script I get following error message: Script-Fu error when executing (script-fu-glogo-simple2 35 219 /tmp/x.gif Error: unbound variable (errobj /tmp/x.gif)

I found in the tutorial following hint: http://www.seul.org/~grumbel/gimp/script-fu/script-fu-tut.html ----------------------------------------------------------------------- You might also want to open a directory and open all the images in it. Not even that is possible. The SIOD webpage describes the opendir function, but when you try it in Script-Fu it will not work as many other SIOD function. => (opendir "/")
ERROR: unbound variable (errobj opendir) To solve this you have to work-around this by dumping the directory contents to a file and read that file instead, or you can write a Perl-Fu, Python-Fu or a Gimp Plug-in. ---------------------------------------------------------------------

Does this mean, I will never be able to save any files in script-fu?

I have no chance to use perl or python, because perl needs gimptool, I do not have, and python for gimp tool can not be found on the web.

Thanks in advance for any hint, -eleonora

With SF_STRING or SF_FILENAME the error remains the same. Error: unbound variable (errobj /tmp/x.gif)

How do you run the script?

Use SF-STRING or SF-FILENAME, not SF_STRING, SF_FILENAME.

If that does not fix your problem then post your script; it is difficult to find bugs when only fragments of code are provided.

Hello,

I use SF-WHATEVER, I just had a typo in the email. The complete script is my previous email and also attached to this email.

I test by copying the script into /home/en/.gimp-2.2/scripts, and then do a refresh from gimp/Xtns menu.

A reference script copied from /usr/share/gimp/2.0/scripts works perfectly; however not a single scm script does file operations. I suspect, that file operations simply do not work with scm. That what the tutorial implicates.

Does this mean that you are using GIMP 2.2? This is long outdated. In the meantime the Script-Fu interpreter has been completely replaced.

The tutorial is probably about as outdated as your copy of GIMP. File operations do work fine. At least with a recent copy of GIMP. Please do not waste our time and update at least to GIMP 2.4. We can't give any support for older versions.

I did not realize you were trying to use that script exactly; I thought you used it as an example in writing your own script. That script is over 10 years old and written for use with a very early version of GIMP (GIMP is only about 11 years old). It will not work with more recent versions of GIMP because of changes over the past decade. As an example, your script uses the PDB function 'gimp-drawable-color' which is no longer available.

A reference script copied from /usr/share/gimp/2.0/scripts works perfectly; however not a single scm script does file operations. I suspect, that file operations simply do not work with scm. That what the tutorial implicates.

The tutorial you cite is more recent -- it is only about seven years old -- but is still too outdated to be used without compensating for changes that have taken place in the meantime. GIMP now employs a different implementation of the Scheme language interpreter, and the Scheme language itself has evolved over time.

File operations in scripts are typically limited to handling "image" files, but they are present and they do work. In fact, there haven't been many dramatic changes in this area over the years (the problems with your script have nothing to do with its file operations).

If you describe what it is you wish to accomplish, I should be glad to assist in writing a script. For such scripts to be effective, by their very nature they must be customized to match the workflow of the tasks being handled -- once you start making the script flexible enough to handle multiple situations, you end up with a workflow just as involved as performing the steps manually (this is why you don't see many "file operation" scripts being widely distributed).

A generous offer. Thanks in advance. All I need is:
I do not work with layers, just with gif pictures. I select part of a gif picture and put it into clipboard, then create a new gif picture. (2-nd menu column: create new picture). So far everything I do manually.

Now: I'd like to write that new picture into a file I give the name, as a gif file. It should not ask any questions, after it knows the file name, it should write out straighforward the gif file. That's all.

At present I write out hundreds of such little pictures, and at each time after ctrl-s standard gimp asks 2 stupid questions I answer with yes, and that takes a lot of in fact for me useless mouseclicks. I'd like to speed up my procedure by that script.

Thanks a million in advance for your assistance, -eleonora

#1. Is it possible to have the outputted filename derived from the original image's filename? For example, if you are selecting from an image named "somegirl.gif" then could the script assume that the output filename should be named "somegirl-cutout.gif"?

#2. Is it necessary to create a new image from the copied region? And even if it is (e.g., you want to edit the pasted image), would it be acceptable if the script performed the creation of this image. I.e., you make your selection and then run the script -- the new image is opened (if necessary) and then saved as a GIF.

Item #1 would eliminate the need for a dialog box prompting for a filename (and would provide an easier way to handle directory paths). Item #2 would be necessary to accomplish Item #1 -- once you have created a new image, information about the original image is no longer accessible.

If you choose to have the filename of the selected region automatically derived from the original filename (i.e., you make a selection, then run the script to save it to a GIF) then would you want further selections from the same image to overwrite the previous one; or would you rather that the filename be modified to indicate a "version" (e.g., "somegirl-cutout_1.gif")?

Of course, doing precisely what you described is possible; it just entails some steps that might better be automated.

You are aware that you can ackknowledge the default settings in these dialogs by pressing the "Enter" key, aren't you?

Yes, thanks. That's what I do; for 100 pictures that is 200 keypresses. I'd like to avoid them altogether.

No. Picture 2 is derived from the page number where it is, for example the first image on page 3248 of picture 100.gif is called 32481.gif, picture2 32482.gif, etc... page number is contained by the original picture, and has nothing to do with it's name. Original picture is called in the example 100.gif, and the derived pictures are called 32481.gif, 32482.gif and 32491.gif To find the proper name is job for a human, the machine can not effectively help there.

#2. Is it necessary to create a new image from the copied region? And even if it is (e.g., you want to edit the pasted image), would it be acceptable if the script performed the creation of this image. I.e., you make your selection and then run the script -- the new image is opened (if necessary) and then saved as a GIF.

The script is unable to create the images. They must be created manually. They are pictures in written text, and only a human can decide, which parts are images and which parts are text. The selected part then usually gets modified in size and also sometimes rotated. All jobs, only a human can do properly. I checked with the most up-to-date ocr programs, they do a lousy job when they try to find out, which parts are pictures and which are text. They err in 20-30% of the cases, which is completely unacceptable and unusable for me.

Of course, doing precisely what you described is possible; it just entails some steps that might better be automated.

That exactly would speed up my work by at least 20-30%.

Thanks, eleonora

Here is the script. I tried to write it so that it would run on GIMP 2.2 (as well as 2.4 and 2.6) but I have only tested it on version 2.6.

http://flashingtwelve.brickfilms.com/GIMP/Scripts/fast-gif-save.scm

Saul, Thanks!

When I try to save a file, I get following error message (2 messages on one window): 1. there are not enough layers marked as 'Visible' to do the function 'join visible layers'. There must be at least 2 layers. 2. script-fu error when executing sg-fast-save 3.6 /tmp/Untitled.gif Error: procedural database execution failed (gimp_image_merge_visible_layers 5.0)

I then added a layer (ctrl-l, duplicate layer) and then the script saved correctly /tmp/Untitled.gif. I hope, you know how to fix this,
Thanks eleonora

In this case, it just so happens I do*. The problem is that you are using a version of GIMP which is over two years old, and the best "fix" would be to update to a newer version. If for some reason this is not possible, here is a version which should function with GIMP 2.2:

Thanks again, this version works perfectly. :-)

Is there a way to assign some keyboard shortcut to this script? That would speed up me even more. (For example ctrl-1 or something like that)

I always considered gimp reinstalling/update as a big deal. Am I wrong? I use debian linux.
