I am having trouble opening a few jpeg2000 images in Photoshop CS2 in Windows. I get the following error: "Could not complete your request because of a problem with the file-format module interface". I DO have the JPEG2000 plugin installed. I am wondering if there is a file size problem. My files are quite large because they are scientific data (up to almost 6GB per image). I can open some jpeg2000 files, but not others. The ones that I cannot open are over 4GB in size, while the ones that I can open are closer to 1.5GB. Is this an obvious Photoshop problem, or is it more likely that my computer needs more RAM? The reason that I suspect that the answer is the former is because a colleague has a Mac with lost of memory (okay, can’t remember the number, but it’s a beast) and is having the same trouble opening these files.

Is the file size 6GB? Or the opened image?

You may want to look into the pixel limit of JPEG2000 (if any)

PS can handle up to 300 000 x 300 000 pixels which means PS should not be the problem if your image size is 6GB (assuming sufficient RAM and Scratch disk)

If the files over 4 GB fail, then I think it’s a bug in the JPEG2000 plugin.

Can you put some of those files onto DVD and send them to Adobe for testing? Contact ccox at adobe dot com for mailing details.

This is a reply to both Cybernetic and Chris. The file sizes I listed are file sizes. They are bigger when opened in Photoshop. The images can be opened in Lizardtech ExpressView with not much problem. Other people, more knowledgeable than I, have been having the same problem with Photoshop CS2, apparently with file sizes over 4.8 GB. I don’t think that these data exceed any pixel limit of jpeg2000 since they can be opened in Expressview. Unfortunately, these data have not yet been publically released, so I can’t send any examples. But you can find data of this type at <http://hiroc.lpl.arizona.edu//images/>. The images I am talking about have larger file sizes than those which have been publically released, but at least you can get an idea of the type of data I’m talking about. Thanks for any help you can give.

I’m assuming you can open these (much) smaller images wihtout a problem.

Do you know the pixel count of the files you cannot open? Does it exceed PS’ limit (300 000 pixels)?

Can the LizardTech software save the image in any other format? If yes, can PS open those files?

If not, my suggestion is to get an image you can release and send it to Chris.

Yes, I can open the smaller images without a problem in Photoshop CS2.

An example of a file which would not open on a Mac in Photoshop CS2: 17,770 pix x 48,841 pix: 867.9 megapixels as an opened file jp2 file size: 361.4 MB
opened in Graphic Converter, not Photoshop

Apparently, from experience of several people, the limit for Photoshop on the Mac appears to be about 360 MB file size (about 800 MB opened) and for the PC about 2 GB file size. Most computers incolved have 4GB of RAM.

Yes, one can save as another file type in Expressview, but at highest resolution, it only saves what’s currently on the screen. Expressview never displays all pixels at once which is why it’s "express" I guess.

Here’s an example of publically released data with a file size of 431 MB (i.e. too big for the Mac, apparently). You can easily download it from <http://hiroc.lpl.arizona.edu//images/PSP/PSP_001408_1900/>
Just click on the Full-Scale JP2 link on the right. There aren’t any publically released data that are >1GB in file size, so that’s the best I can do for an example now.

Thanks again for your help.

I do wish those people had reported the JPEG2000 problem to Adobe so that we could have fixed the bugs sooner. It’s kinda hard to fix bugs that you don’t know about…

And we will need some sample images to be sure that we have adequately addressed the bug (different JPEG2000 libraries do things a bit differently, so we need to make sure we address it for whatever files you are using). The files will not be made public, and will only be used to test the bug and regress it later (so it doesn’t get rebroken down the road).

I tried opening that file, but PS seems to hang. This may very well be because I have an older computer and only run CS1.

Sorry…

Meanwhile, if you really can’t get a release to send a file to Chris, can’t you create a file with bogus content to send to him?

I downloaded the 431MB JP2 file at <http://hiroc.lpl.arizona.edu//images/PSP/PSP_001408_1900/> and Photoshop CS2 / WinXP couldn’t open it; it grumbled, "Could not complete your request because of a problem with the file-format module interface."

Hi. Thanks so much for your help. I really don’t think that I need to send you any more data than what’s available on the website I gave you (and we legally cannot, under NASA rules). The data on that website is from the same source and is the same type of data as the non-released data. The non-released is really no different except that SOME of it is higher resolution or has been map-projected (and hence larger file size). In fact, the non-released data will eventually appear on the same website in the same way. Given that even a 431 MB publically-released image couldn’t open on the Mac or on Michael Sullivan’s computer, the publically-released images seem a good place to start to figure out what is going wrong. I have notified the HiRISE (that’s the instrument taking the images) team about this discussion and all of your replies. I will let you know if I hear anything else from them. This is obviously of concern to the HiRISE team and to the scientific community in general since we all need to be able to look at the data. Thanks again for your help.

Here is a jpeg 2000 image that I have been trying to open for a long time. I hope the link works: <http://memory.loc.gov/gmd/gmd376/g3764/g3764s/pm003232.jp2> It’s supposed to be 9525kb unopened. I have the jpeg 2000 plugin as well, and can only open about half of the jpeg 2000 images I have downloaded.

I hope this helps find an answer!

Is there some reason they can’t make ZIP- or LZW-compressed TIFF files?

I can open that file using Adobe Elements 5.
PS2 & 3 can’t.

It will also open using Ulead PhotoImpact v12.
