Image editor
 

I am not so "New" anymore... bit am now at the stage to start finding apps that I need for my regular activities.

I have installed GIMP and PINTA for image editing, they each have a place for those jobs, but both are missing an important function (for me).

I need a tool that I can grab a bunch of images, and execute a batch job to reduce those the same size and not have to go through each one again and again.

In my "Windows" days, I used an app called iRfanView, but it is only for Windows users.

Is there any utility that you know can do this job in Linux / Ubuntu 20.04 ?

I am of course searching, but none that I have seen so far mention such an option.

Thanks
Alex

I use only one Windows app nowadays - IrfanView. For what it does, I have tried a lot of Linux graphics utilities and none has replaced it, unfortunately. For me, it runs flawlessly under Wine.

I think that imagemagick is the go-to tool for batch-resizing images.

gimp supports a batch mode.

imagemagick ?.

Thanks. When I made the move to Linux some 3 months ago, this was for me a one-way action.

I am determined to never go back, no Wine, no Windows.

Yes, irfanView is a very good tool

Cheers

GIMP is a good tool, but complex. If I have no other option, I will use that.

Thanks

Forgot to mention... After 30 years with GUI / Windows, I am not excited to go to using Terminal mode, if I can find a GUI alternative

Thanks

^ not FOSS.

alex4buba, most native Linux image viewers offer additional functionality; you will have to try them all out and find the one that suits you.
Likely candidates not yet mentioned: gthumb, mirage, geeqie, eog, gwenview, nomacs, phototonic ...

Yes, I am sure you are right. Just downloaded and tried Converseen. It does the Compression part very well, simple to use. But, has no Trim option, so will continue searching.

Thanks for the list you provided

If you've used systems for 30 years, then likely this stretches back to 1990 thereabouts. MS DOS was one of the primary things to use back then, mainframes where people used things like SUN workstations and VAX terminals were a big thing and all of it was command line. Windows didn't really get to be very proficient with having a GUI until Win 3.1 came out and grew a bit in proficiency. But even then batch files and DOS commands were the ways people got stuff done. Assuming you've worked with those types of situations, or something similar.

Sorry to say, but your original problem here screams to use one of the programs cited, in batch mode. To whit, most of them you can run them and they'll bring up a GUI, but also you have the capability to construct a command line set of arguments where it will not raise the GUI, but perform transformations on the inputted file. Said inputted file can be something like a wild card, or a bash list which you construct.

I have performed things very similar to this. I had to prototype a piece of monitoring software using a camera which recorded screen shots that I had to write instructions to add information to the frames and then concatenate the frames into a movie, and then adjust it several times due to the "preferences" of the customer's needs. I used one or more of the several image editing applications, exactly in a command line form, with arguments to cause the transformations desired, all in a batch file, or rather a script.

While you may eventually find exactly what you're seeking in a GUI application, I evaluate the probability there to be low, and recommend you "give it a try" and do your changes to one file, using one application, be that gimp, lview, gwenview, shotwell, etc, get that one file the way you want it, and then you can explore a way to have it perform this same operation on many files.

Let's put it this way, you know very well that many photo editors will do exactly as you wish if you use the GUI form of it. But making mouse actions and automating them is difficult and inefficient, if not infeasible.

As I've said, had to do something like what you wish, alter a bunch of image files. So upon obtaining help from whichever photo editor application usually gives on the full instructions to do things like trim, resize, or adjust using filters, to an image. That's why I recommend, give it a try with one image. After that you can then work on some way to do this with all the intended files you wish to transform.

Don't care!

It does the job and is free for personal use.

alex4buba,

Despite your reluctance to use the command line, I think Imagemagick will do the batch resizing you require.
