Re: [Gimp-user] Opening uncompressed NASA image files in GIMP



If you show the folder structure in Finder, you can use finder. Otherwise
use the cp command.

Thanks for the info. I’ll try to get a working plugin now that I’ve found
the plugin directory at
rickkline/Library/Application Support/GIMP/2.10/plug-ins

Do I need to use the cp command or can I copy it in Finder?

Thanks.
Rick

Like magic: changed file type to .data
GIMP opens with width, height, offset (which I ignore, because I can’t
find a proper header descriptor) and image type.
Set height and width to 1024 and 1024, file type to Gray unsigned
16-bit Little Endian, and it opens as desired.

I downloaded the source for the 2.4.116 version of the PDS plug-in for
GIMP. To build it for Linux (I don't have access to a Mac) I needed to
comment out the include of the gimpcompat.h in the pds.c file.

I told gimp 2.10 to load the 1p157746813eff40b8p2363l3m1.img that you
mentioned as a sample. It loaded the image up right away without asking me
for any information. I did not have to change the file selection or tell
GIMP what type of file I'm loading.

I have no idea what I'm looking at in the sample image but the plug-in
works. What I have found is that GIMP 2.10 hangs when trying to view the
image properties.

FYI, in the pds.c file that is in version 2.4.116 of the plug-in it says
it "Loads files of the NASA PDS image format" with supported file
extensions: img, imq, pds, edr, bb1, bb2, bb3, bb4, ir1, ir2, ir3, n07,
n15, sur, sun, red, grn, blu, sgr, vio, qub, or lbl.
