Batch Photo Resize App?

[logan01]

I tried "Converseen" changing a few pics from 1000x750 to 640x480 (pixels option). The app indicated the "conversion" was a success however when checking them, they weren't changed. Any other simple software you recommend for batch resizing? Thanks.

(Not a photo expert here ... ) I've been using Gwenview: highlight a bunch of photos, right-click and Open with Gwenview, click Plug-ins in the topmost menu bar of Gwenview, Batch processing --> Resize Images. Works really slick. I can't recall, but you may have to install (using Muon Package Manager or some-such) the plugins package for Gwenview -- someone else here will probably know.

Digikam has a Batch Processing tool. It is very easy to use and very flexible.

I just checked my Muon Package Manager, Gwenview is installed (of course) as is
kipi-plugins-common
libkipi11
libkipi-date

which is probably that plug-in business I'm not remembering ... the Batch-processing capability comes with the plugins.

If you have imagemagick installed, "convert" should do it:

convert someimage.jpg -resize 640x480 someimage.jpg

This replaces the original with the new size. To keep the original, use a different target name:

convert someimage.jpg -resize 640x480 small_someimage.jpg

Convert by default preserves aspect ratio. To force new size regardless of aspect ratio:

convert someimage.jpg -resize 640x480! small_someimage.jpg

to "batch" it for a whole directory full of files:

for file in *.jpg; do convert $file -resize 640x480! small-$file; done

Lots and lots. Thanks guys. Gwenview worked just fine. But of course I'll check the others too. Thanks again.

If you have imagemagick installed...

+1
imagemagick exists for this sort of thing. However, there is a long learning curve (if not particularly steep).

Yes. But as there are easier ways, I can't see many photography types wanting to struggle with the command line.

Waaaa? No command line Geezzzzz...

I suppose you're correct. However, in case you were also a linux geek (as well as a photo geek) I felt it deserved mentioning. Now if you wanted to be "cool" to the other photo geeks, you could write a set of scripts to complete your most common tasks or even automate them.

Seriously, the power of Linux lies at your fingertips. For example, lets assume you do the above operation often - even daily. The GUI steps might look like:

1. Copy files from camera to a folder on your drive using Dolphin.
2. Open Gwenview in that same folder and select all the files (It seems you have to add a plugin to Gwenview before you can do this? I couldn't figure it out.).
3. Do your batch resize.
4. Clean up files (move to desired target location, etc.)
5. Close Gwenview and Dolphin.

Now, if you spent a couple hours preparing your install, you could: Have a UDEV rule that auto-copied all your new photos from the camera when it was detected at plug-in, have a script running using inotify to detect when new files were added to your target folder, and have the above script resize and clean up the files, and notify you via a pop-up that the work was done. So the list of tasks would be reduced to simply plugging in your camera. A couple hours of setup time, you could have totally automatic and hands-free functionality.

More than any other reason; this is why I use Linux. Because I am in total control and can, rather easily, make it do almost anything I want.

Sometimes you need to do a customized re-size on some photo(s). Of course, if you maintain the originals, that sort of thing could be checked later, after the batch re-size.

Also, there is the portrait versus landscape photo. Of course, you could test for that (1st dimension > 2nd dimension sort of thing) and separate the two sub-batches.

Yes, it all depends on what you are familiar with. I think it is important that "everyone" should get the benefit of a sleek process. Not just the geeks.

Incidentally, the DigiKam batch processor does what your scripts would do, in one go. The GUI shows recent batch processes that you can re-use and edit. And displays all the settings for the various tools all in one place. And notifies you when it's done. It is already in wide use.

I wouldn't know where to start creating a script or what UDEV is. The command line is unfamiliar territory to me, as I never need it.

Thanks. I have KDE 4.13.3. I'm following instructions to install to KDE 4.x. But it's not working. Here's my Konsole attempt:
