Hello!

I've got several jpeg files of non-standard sizes (I mean most of them are different but some are the same). And now I'd like to change resolution of all of those files to one, standard for all of them, size. I need to rescale the picture by e.g. 80% but for each file this value may be different and needs to be recalculated. I do this with the use of MS Paint in Windows and I found it too slow. I guess it can be easily (or at least in shorter time) obtained in Gimp. I already installed Ubuntu 9.10 Linux so I've got Gimp. Later, I need to make other set of all these pictures to other, also standard, miniature size, needed for thumbs. Can anybody help me to make my task easier and faster in Gimp, please?

Greetings!

found this plugin in the pliugins registry which might fit your bill. Its certainly worth looking at.

Thanks!

I think this plugin is exactly what I need to have. However, I've got difficulties with installing/using the plugin. I tried to follow http://www.youtube.c...h?v=c06gzADXVvA i.e. I copied it to the given directory and I cannot see it in any of context-menus (by right mouse button) in Gimp. It may be because I don't understand explanation of usage in Italian :-).

It is not in Right click menu but here Filter\Script-Fu\ATG\Auto-convert-and-resize.

I am Italian but translate that is quite heavy ( i miss some of the equivalent English term )

To give a idea, there is a lot time wasting steps, as

1 write in a text file the path of all files
BUT only one path for line of text
path should be enclosed with " "
If only 1 of " is missed the script will crash
then script has some severe limits (as example the images may be saved only in the original folder(s) )

Author don't say if on windows you should use Win or Linux style paths

I use mostly Windows and i prefer use Xnview ( http://www.xnview.com ) for batch operation

But if you want limit to open source (xnview is free but not o.s) and to Gimp plugin this
http://members.ozema...odsond/dbp.html
may be a more interesting option

In both cases you will have no problem of translation

Thank you for your answer! However - what should be the name of the file (this one in which I cannot forget any quotation mark) and where should I put it?

I just having problems with another script of same author...i did not want try to use it , i much prefer use xnview

So i may just offer a translation of the instruction of that plugin no idea if they make sense or if the plugin will work

##############################################################################
author say to prepare a text file with the paths of the files to resize or convert
The path is what you may seen right clicking on 1 of the files you want process , and then looking in propriety and then adding the file file name

a example is needed you may want resize "image.jpg"
in proprieties of "image .jpg" you may notice a path maybe something similar to
C:Documents and Settings/Your Name/Document/images/my photos

So the path you have to write will be "C:Documents and Settings/Your Name/Document/images/my photos/image.jpg"

Repeating that for a lot of files in different folders seems to me a nightmare,less painful if are all in the same folder , because you will only to change the last part of the path as for example

"C:Documents and Settings/Your Name/Document/images/my photos/image.jpg"
"C:Documents and Settings/Your Name/Document/images/my photos/image1.jpg"
"C:Documents and Settings/Your Name/Document/images/my photos/image2.jpg"

But note to "image1.jpg" "image2.jpg" and so on must be replaced the name of your images , names that i can't guess

Again in my opinion that make sense only if you know some basic command line commands, so you may get as text file the list and the paths of all files in a folder quickly...if not seems quicker resize one by one then get all paths right

And will be much quicker use xnview that just require you to graphically select the file to process and a output folder

Thank you for your answer :). I've got rather good knowledge about Windows. In Commands Prompt it would be something like "dir /s /b > output.txt" or similar, I just need to check it. I've got no difficulties with checking full path in properties and so on. But I lack knowledge about Gimp and Gimp's plugins. I asked to which folder I need to save this file with all paths and what should be the name of this file with list of files. I'm going to check this xnview later. Where to find some step-by-step instruction how to use this xnview for what I need? Thanks once more :-). Greetings!

.

In both cases it is not specified in the Italian page
maybe the plugin has a text input field were paste the text or a search button to locate the text file

In this case no much instruction are needed but anyway is all detailed in the included help (key F1..or in the "info" menu )
All batch operations are in the "tool " menu , "batch processing" has also a key (Ctrl U )
