i just installed gimp 2.8.

i downloaded a book in .gz which when unzipped yields 517 sequential .jp2 files (each sequential file of course yielding a page of the book). How can I use gimp to open these .jp2 files sequentially?

There is a script for GIMP someone has written that allows somewhat easier sequential processing of images:

If you just want to read the book, use an image viewer.

For example, most Linux systems have qiv, which will let you page through the images with space and (oddly) backspace to go forward and back. Luckily, backspace doesn't delete the image :-)

If you're not using a GNU/Linux™ system (which seems likely from your mention of Irfanview) and are using a Microsoft Windows system, say, search for a jpeg2000 viewer for Windows.

Thank You Bob.

But I need to confess that I'm a newbie and I don't know how to use an .scm file;am I supposed to place it into a specified gimp folder? And do you know whether it will work for .jp2 - I see that it accommodates .jpg but I don't know whether that means that it will accommodate “jpeg2000”

From:
http://www.mahvin.com/2009/09/gimp-how-to-install-scripts-plug-ins-to.html

"In Windows Vista [ajnd presumably later version of Windows], the path to the GIMP scripts folder is C:\Users\Your User Name\.gimp-2.6\scripts."

It might even be ".gimp-2.8" if you have a later version of GIMP.

Put the .scm file there then start GIMP.

But as others have suggested it's probably better to use a simpler image viewer. I don't use Windows much now, but I imagine the Microsoft image viewer included with Windows should have a means of simply going to the next image. Probably arrows left/right somewhere on a toolbar.

What's the difference between a viewer and a converter?

An image viewer is something you use to view a lot of images -- what you're trying to do with this book. (Though why anyone would distribute a book in as a bunch of jp2 images is beyond me.)

An image converter sounds like something that converts from one format to the other. For instance, if you used ImageMagick to convert all those jp2 files to JPEG or PNG.

GIMP is an image editor, for creating new images or making changes to existing ones. It's cumbersome to use for viewing a long sequence of images one after the other because that's not what it was designed for. If you wanted to take a few of those images and change the color of the pages, or add drop shadows on the text and flowers around the border, GIMP would be your tool of choice.

i have not encountered anything native to windows 10 that opens .jp2;

Regarding Windows 10:

https://en.wikipedia.org/wiki/Windows_Photo_Viewer

Not sure if it does .jp2 but doesn't seem promising.

that's why i'm trying so many third-party softwares - the latest being http://www.fastone.org .. and this latest too does not seem like it's friendly to a tablet with touchpad keyboard or else i don't understand how to work it: it's requiring an immense time to create thumbnails for the 517 .jp2 pages; and i see no way to use its slideshow feature without first creating these thumbnails; and i see no way to view this book without using the slideshow feature.

Irfanview has a plugin that includes JPEG2000 (plugin zip file #2, "formats"). Try that.

When you have an image open in Irfanview, the top tool bar should have left and right arrows for moving to the next image.

http://www.irfanview.com/screenshot/big/01_viewer_xp.jpg

i tried using the gimp 2.8 .scm that Bob mentioned; the script's window does indeed appear but i can't understand how to operate that either!

File|Sequential|Open First File... to navigate to the directory and open the first file. But the script does not include .jp2 files in its list. Probably easy to modify the script to do that as it is a text file). GIMP 2.8 itself will open .jp2 files. And to avoid having to always do File|Sequential... etc. you'd also want to assign a shortcut key to close and open the next file.

But that all seems as if it's getting to be too much.

For Windows, Irfanview is excellent, so I'd be spending my efforts getting that to work. You'll probably end up using it for other things, too.

I had written:

But the script [to sequentially open images] does not include .jp2 files in its list. Probably easy to modify the script to do that as it is a text file). GIMP 2.8 itself will open .jp2 files.

Well, I modified the script so that it does open a .jp2 file. But when it comes to closing that image and getting the next there is an error from GIMP, as GIMP can't write .jp2 format.

I don't understand your distinction between successor "page" and "file". You say your "book" consists of many images, one per page. As far as image editors/viewers are concerned, an image is a file (ignoring complications like layers).

I've never known Irfanview to default to starting full screen, but it is an option in the preferences, anyway.

Even when you are in full screen, the left and right keyboard arrows navigate backwards/forwards to the next image in the directory.

Attempting to read a book by individual images seems to be the root problem. Perhaps try converting them to something like an .epub e-book format and then use an e-book reader. I've not ever done that from images, but there are converters out there. But even that will have difficulties, given the text will not be able to flow to suit screen size.

and iv is most unfriendly to touchpad keyboards. thus, iv has thus far been of no use to me although it was one of the first that i tried - that's why i'm still searching. (btw, many softwares - including Windows! and Google's Gmail- are inconsiderate of touchpad keyboards.)

Can't help you there. What exactly is the device you are using?

A slideshow does not seem to be the way to do it. There is no guarantee that you will have finished reading the page before the next image appears.

Simply open the first "page" (or the page you are up to) of the book as a single image in Irfanview. Not as a slideshow. Then when you have read the page there should be left/right arrows on a toolbar. Or, use left/right arrows on the keyboard.

Show us a screen shot when you open that first image.

But I see you have selected the slideshow without automatic timed advance, so it should work that way.

Once you start the slideshow, do you actually see the content of the "page"?

Have you done "Add all" to select all the images for the slideshow?

i can see no way to display a slide show other than 'fullscreen'; fullscreen seems to be the only way that irfanview will display a slideshow. but fullscreen obliterates access to the the touchpad keyboard and the iv toolbar and obliterates access to almost everything: the only option that i can still control is 'shutdown' and 'restart'! ... nor do i have a mouse.

Again, what device are you using? Is it some sort of tablet without physical mouse or keyboard?

although i repeatedly opted for it, the toolbar does not contain the buttons for 'next page' and 'previous page' - even if i were able to access it.

When you say you don't have a mouse, do you mean you don't see a mouse pointer when in full screen? That's possible. Hitting the "ESC" key should exit slideshow mode, I think.

Of course GIMP can open jp2 files. Where did you hear that it cannot?

I presume you are asking me about "official build". Michael can tell you more about it.

It's the build provided by GIMP maintainers. If that build does not include jp2 support, you'll have to ask Michael.

My builds obtained from my website have jp2 support built in.
