[Gimp-user] Multiple file scaling
Hello list, Is it possible to rescale multiple images (ie: hundreds) without having to open each one individually in the Gimp? I guess this would be a sort of batch processing. Background: I have a perl script which I run to shrink images before uploading to the web. This typically shrinks the size (and thus upload times) of my huge 8MPixel JPEG files from 3-4MB to a few hundred KB. This works great, and I use this script all the time. I just thought it would be great if the Gimp could do something similar, as I imagine this shrink many images before upload is a process that many people need to do. Thanks! -Jon -- -**-*-*---*-*---*-*---*-*-*-*---*-*---*-*-*-*-*--- Jon Lapham [EMAIL PROTECTED]Rio de Janeiro, Brasil Personal: http://www.jandr.org/ ***-*--**---***--- ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Hi, you can use convert from ImageMagick. cd /dir/with_images/ for image in *; do convert -scale 100x100 $image $image; done check the man page for more info :) nuno -- Non-free programs are dangerous to you and to your community.

I was just curious if/how the Gimp could do it, as I use the Gimp for all my image processing except for this one step. From what I've found on the net, related to theGimp capabilities to do batch jobs, I can say that you are better suited with ImageMagick and, like you said, your custom perl scripts. I quote: Batch mode is slow. Its not really a practical replacement for tools like ImageMagick or NetPBM when it comes to large scale image conversions or similar. At least not without writing some very clever scripts. The problem with this approach is that gimp/script-fu has no built in procedures to itterate though a list of images. So you cant easily tell gimp to load up *.jpg and run predator.scm on them, at least not without it taking a _long_ time. So you could write a shell script to fire up gimp in batch mode for each image, but that starts a new gimp for every image. And gimp startup time is very very slow, especially if you plan to repeat ir a few hndred times. src: http://adrian.gimp.org/batch/batch-7.html nuno -- Non-free programs are dangerous to you and to your community.

I do not think anyone has ever disagreed with the idea that more Mail programs should include this feature.

Re: [Gimp-user] Making GIMP a little more tablet friendly, maybe?
Hi, Francois du Toit [EMAIL PROTECTED] writes: I wanted to suggest something similar. To not make gimp more configurable just because there's no space in the user interface seems silly to me. Make the feature configurable so the user can use gimp the way he/she wants to. If it clutters up the user interface then stick it in a config file where it won't bother anyone who doesn't want to change it. That's what we do anyway. Not all options in gimprc are actually accessible from the preferences dialog. That doesn't change the fact that user configuration makes life harder for the developers and for the people documenting the software. But really, there's no problem with adding yet another configuration option, I would just like to avoid it if possible.

Andreas, Not sure what is going on in your Thunderbird, maybe a setting or something, but reply should send it right back to the mail list. No, Thunderbird should not reply to the list with the current settings of the list. There is no Reply-To header, thus a Reply has to go to the address in the From header - which is the address of the original sender, not the list. The List address is in the To field. Thus only a Reply All will go to the list as CC (and to the original sender as TO). Don't blame my mail client for the set-up of the list. 15 out of 17 mail lists I read have a reply-to header with the list address, the only other list which has one is one I only read and never reply - with those 15 mail lists, a Reply goes to the list. Usually Thunderbird is quite good at doing replies, so I'm thinking maybe a setting is off on your end. Definitely not.
