Anyone know of a real BATCH picture resizer?

by jagman_55 / July 5, 2012 12:18 PM PDT

For over 2 years, I have searched for a TRUE BATCH image (picture/JPG) resizer that will process in TRUE Batch and not ONE folder, one screen etc.
Most large picture collections come in SETS, and some have lots of them and they are all different size images depending on the resolution you need. But to store for archive, you need to reduce the size, etc.
In 2 years I have not found any resizer that can handle more than the TOP level folder and NO sub-folders.
Yet most collections come in multi-sets are in multi-folders but all software I have found can only resize ONE picture or ONE folder at a time, which is typically 30-110 pictures and with some having hundreds of sets, meaning thousands of pictures, that is what is called labor intensive doing them a hundred at a time.
Has anyone found a picture resizer software that can handle the top level folder and/or its "sub-folders" and keep them straight? This way if you have thousands of picture, you can load up, leave over night or do something else instead of setting there and waiting for one lousy folder to resize.
Some programmers call their software "batch"; but obviously do not know what "batch" means. It is a old Mainframe word we invented when a computer 'mainframe" could only process one job at a time (PCP) and then multiprocessing was invented and we would 'batch' several programs together. I have been in 'Data processing' about 55 years so i know what batch means. So when I search for a resizer and I find 'batch', the instructions say to 'drag and drop' one picture or one folder, or one screen??

While IMAGE MAGICK is a true command line tool, this failed your requirement of some GUI drag and drop. In mainframe days we would write the batch file to do what you asked. So while I think it fit your batch requirement it failed when you added the GUI interface you wanted.

Didnt want to go back to ancient days of BAT files but...

trying to stay in the 21st century of PC/Windows software, I had to yield to GUI's as even in my SUN SA days, I was force to sometimes use GUI instead of the command line, everyone seem to love them.

What offends me was to search for 'picture resizer' and you get hits on 'batch functions' as a feature but when digging down, you see it was dragging and dropping more than just ONE file, whereas I consider a batch to be multi-folders (Windows world) as most images files are grouped in a folder and collections are normally multiple folders. And every resizer I have found, batch or not, was no lower than 'one folder' level. But bad to me thinking 'batch' as more than 'one'

If I was to write and market a 'resizer' program, I would label it 'batch' only if it handled more than ONE folder, not just more than one picture.
So is IMAGE MAGICK a PC program? or for the IBM Mainframe, Unix, etc? I love command line but in the last 10 years, since my IBM and SUN employment days, I have kind of gotten away from command lines.

I have about 10 terabytes of pictures to resize so using one folder at a time will take longer than my life expectancy.

Batch started as just a stack of punched cards, when things like hard disks and concepts of folders didn't exist yet. So I find your interpretation of "batch" as "can do multiple folders" a little bit stranged.

That said, assuming resizing a folder of pictures is much faster than view tem all, I feel that you have more pictures than you will ever able to view in your life expectancy. That alone makes it a strange task you're planning.

If it's for business, pay somebody to write what you need. If it's for your own private use, start learning programming and write it yourself. If you had started with that 2 years ago, in stead of spending 2 years searching for something that doesn't yet exist, you would have been ready with all 10 TB already. After all, it's only 10 million pictures, maybe even less.

Punch cards?
by jagman_55 / July 6, 2012 8:30 AM PDT
In reply to: Re: batch

Maybe but the question is: Did you ever punch a card on a machine? Do you remember the number of rows and columns? (IBM since they invented them)
Punched cards were my input and output console, as there were no consoles invented but not sure what that has to do with this subject? so to answer you question, no, I have not been waiting but using the crappy software that says it can handle "batches". Actually in my time, batches did not exist. And since my first computer had 4,000 bits, yes, bits, and images on a computer was punched cards, where we punched the cards with characters, and listed them on an accounting machine that "drew" the picture for us. I even remember the first one, someone punched a nice looking naked woman of O and I and was about 5 pages of listings. And the only storage media was punched cards but TAPES were on the way. Using an IBM typewriter as a console to replace punched cards was a real advancement. So yes, i expect those that follow to try to keep the tradition going but keep it straight.

But a google of IMAGE MAGICK finds it's for Linux (UNIX varient?), PC (is that Windows?) and other systems.

Back to the requirement. Let's say this is the requirement. Now you need a programmer. At least with Image Magick the resize is just a command line away in said batch file.

Should have clarified and been more specitific

In reply to: Sorry

I am now using Windows 7 on all my PC's. Although I prefer Unix based, popularity of Windows seems to be the public's darling now.
So for my image/pictures, I use software written for Windows 64bit like it or not.
Some pictures are OK in the megabyte range but I try to cut their size down to 100k to 500k for storage.

The best program I have found to do it quick and dirty is Quick Picture Resizer but it only takes one folder at a time. You just specify what you want, drag and drop a folder and do something else.
The problems is, most all the programs I use are written for Windows today and not Unix, Linux, etc.
I was just hoping to find one that could handle 'sub-folders' but can not find any as i would be able to load up and process overnight.

But Thanks.

Has some interesting features and is free.

Will try to hack through the docs.

FastStone Photo Resizer
by KenHusveg / July 6, 2012 5:13 PM PDT

ImageMagick (already mentioned) is a very good tool, if you know what your doing.

FastStone Photo Resizer (stand alone or included with FastStone Image Viewer) is excellent and easy. It can do all your asking, if you dig around a bit for the advanced options.
