loading jp2 images

Hello,
I am trying to load a JP2 image from the USGS. from the metaviewer i have:
BitsPerSample 8 8 8
Photo.ColorSpace sRGB
From image properties:
Size in pixels: 6963 X 8854 pixels
Color Space: Grayscale
Number of layers: 1

There is a color image there, it shows in qgis. How do i get gimp to load the color image?

Hello!

You'd have to tell us four more things:

1. Version of GIMP 2. Operating system and its version
3. Whether you see any error messages 4. Whether JP2 is listed in the file type selector in the Open File dialog

That's a JPEG2000 format image.
It allows larger colour depth and lossless compression, compared to JPEG.

Gimp up to 9.2 couldn't open them. I doubt 2.10 can.

You can convert them to JPG or probably to TIF and those are both openable.

This is simply not true. GIMP has been able to open jp2 files for quite some time.

It simply means that you're missing jp2 filetype from your GIMP build.

Interesting, now that there is a reference image.

Using ImageMagick (IM) identify - the jp2 is 8 bit grayscale with alpha. AFAIK IM uses the same libopenjp2 library as Gimp.

However, using XnViewMP the image displays as RGB. Converts to a large tiff (with alpha) which does open (with complaints) by Gimp 2.10.14 (using kubuntu 18.04)

At least that will get the image into Gimp.

You're obviously resourceful. :)

Anyway, that image opens as grayscale for me. As a check, I opened it in Photoshop and that's a single layer grayscale as well.

I initially thought it might be an old version of lib libopenjp2 (ubuntu bionic uses 2.3.0 ) but trying out an appimage with the latest 2.3.1 makes no difference.

Might be this for you clever guys ;) If I use imagemagick identify -verbose, end of the report is:

I still think an libopenjp2 issue rather than Gimp.

Psot=12 implies that it's a special case that can be read by Kakadu. Otherwise Psot has to be greater or equal to 14.

I used the Kakadu demo viewer and it still shows me 1 grayscale layer. Sorry, this is where I stop. :)

If anyone's still interested, irfanview 4.50 32-bit (on windows) opens the image and shows a very large, color, arial view of some rural, green countryside.

It looks like the kind of hacked-up stuff that Map Suite does:

https://github.com/ThinkGeo/MultipleJpeg2000RasterLayerSample-ForWpf

I could be entirely ignorant on this, but if someone extends a file format beyond what it was designed to do, expecting other applications to just support that would probably be a bit on the optimistic side :)
