JPEGCrops - Suggestions

I won't make any significant changes to JPEGCrops. Instead I'm working on its successor, which will (probably) be named RoboCrop. It will be a complete rewrite, in order to make it possible to do things like red-eye removal and image resize. It will also be freeware and the interface will be roughly the same as JPEGCrops.

Feel free to make suggestions for RoboCrop features or report bugs for JPEGCrops. If you want an answer to a specific problem, send me an email at darkwing@daimi.au.dk.

Please take a look at the future page before posting. What you want might be on the wish-list already. You might also want to view the old suggestions.

Hello! I posted this in the Robocrop page by accident. But I have another question! When I open 200 high resolution images at once to do a batch crop on them, I get an error saying that the processor has run out of memory, but I have a Dual Core 3Ghz with 4 GB RAM. Can JPEGCrops just not handle this many photos at once? Thanks!

I an sorry, but this is a known bug that is very hard to fix. Your system runs out of resources, not RAM. The amount of available resources can be tweaked, but it is not a recommended operation. The exact amount of photos that a given Windows system can open with JPEGCrops varies, but 200 is normally too much and I have never heard about problems when opening 100 photos.

The size of the photos does matters very little as JPEGCrops only decodes enough information for the given display resolution: 200MP JPEGs is not a problem.

Thanks for the heads up! I was wondering if there is any hardware or OS upgrade that I can do to my computer to increase the number of photos that it can process. I am open to even using a Mac if necessary. Let me know please!

Sounds like you really wanna. Okay, in theory this is simple: Just increase the maximum number of resources by tweaking the registry. However, this always come with a big "Use at own risk"-warning.

Go to http://superuser.com/questions/55891/registry-setting-to-allow-more-open-ie-windows-without-exhausting-windows-resources and perform the subsystems-hack, where you change the value 3072 to something more. It requires a restart. I tried changing it to 8192 on Windows XP and this increased JPEGCrops capabilities beyond 600 images.

Thank you! You're a genius. It works great now (...not sure why this could be harmful to my computer, other than increasing the potential for a crash if too many processes are going on at once. Seems harmless enough, no?).

Thanks again!

Another question! For some reason, the "synchronize crops" option does not seem to work for images oriented as portrait, but it only works for images oriented as landscape. Any ideas?
Thanks!

Great product. I am now having an issue on my laptop it did not have before with the program.
I have windows xp
with ver 0.7.5 beta
When I run it I get the following error-

list index out of bounds(0)

when I click cancel, jpegcrops runs. then if I open an image it gets the error and program hangs.

Any ideas on this?

Davide: The synchronize is overzealous and requires all the images to be of the exact same dimension. Sorry.

Frank: Interesting. I have not encountered that error before. Since it occurs on startup, I'd guess that there is a problem with the Settings.ini-file. Try deleting it and see if that makes the problem go away. Depending on your installation the file is located together with the program files or in your Application Data folder. As far as I remember... You might need to do a search.
