Suggestion for opening raw images

Hi,

Starting a new thread instead of getting this one lost in the last conversation.

Thanks for the suggestions, Liam and Guy. I was at least able to access the PDS (NASA’s Planetary Data System) .img image in GIMP 2.8.20 (!) by changing the image file type to .data.

Unfortunately, there’s no bit depth parameter available. How difficult would it be to provide that in the “Load Image From Raw Data” GUI? P’shop provides the following in their "Photoshop Raw Options" dialog:

If there was even just an option to choose 8-bit or 16-bit image depth, that’d be a big help.

Many thanks.

Rick,

GIMP 2.8.x is 8-bit not 16-bit capable. To get 16-bit capability you need the new 2.10.x version. That's what I have and it does, in that dialog, have options for bit-depth (including Endian options).

Hi Rick,

as Guy already wrote, Gimp 2.8 only supports 8-bit. Gimp 2.10 supports 16-bit as internal format and in the raw loader. And perhaps you are interested, Gimp 2.10 has support for the HGT file format, gathered by the Shuttle Radar Topography Mission (SRTM). I blogged about it here: https://dablogter.blogspot.com/2018/01/gimp-now-supports-hgt-file-format.html

And I have an blogpost how to import the NOAA GLOBE elevation files here: https://dablogter.blogspot.com/2018/09/howto-open-elevation-data-from-noaa.html

What is missing is import of 32-bit float values in the "Load Image From Raw Data"-plugin. I opened a feature for that: https://gitlab.gnome.org/GNOME/gimp/issues/2804

Do you have a link to one of thePDS images?

Regards, Tobias
