[digiKam-users] .fit file format

[rutile]

Is there anyway currently to view .fit format files in Digikam?  Are there
linux/kde/ubuntu libraries or whatnot that can be installed?  If not, is
this in the plans for future releases?

Hi,

No .fit GPS data container is not supported. Only GPX format can be read.

But, GPSbabel open source tool can convert FIT to GPX...

Thanks for the reply, I wasn't referring to a gps format, but the .fit image
file format.

It is used commonly by amateur astro-photography enthusiasts now that there
are 'consumer' grade astronomical registration programs, including Siril for
Linux  :  https://free-astro.org/index.php/Siril

I must admit to don't know  FIT image format, but it sound like a RAW image or something like that.

Perhaps, libraw support it. Can you share a sample file to test ?

I think that should work....

Gimp (2.9.9) can open them with  a prompt for scaling and composing
settings, so there is some linux support for the files.

oops, disregard previous that was a raw file meant for someone else.

This is the .fit file:

GIMP opens 3 (three) images seems to be a 3D raw format :-)

NASA gives lot of infos:

including linux applications

I got it.

Fit is not supported by Qt IO image format plugins de facto. libraw do not recognize too this format as RAW. ffmpeg too. So there is no way to see this file contents in digiKam.

I see also this image containing metadata. Exiv2 do not support this format too.

So to be able to extend this support :

1/ Create a file in bugzilla to register this wish. We can assing this job to a student later. We have a similar subject to extend DK with JPEG 12 bit loss less for medical purpose.

2 Create a file in Exiv2 issues entries in github to support this file format, at least in READ only about metadata.

Note ImageMagick support this format. So code to decode FIT can be found easily to write a dedicated loader in digiKam core.

Great !!!

Look in ffmpeg image supported : FITS is here :

https://www.ffmpeg.org/general.html#Image-Formats

This want mean that we can support this format de fact with small changes done in source code :

https://bugs.kde.org/show_bug.cgi?id=393408

Great!  thank you for following up on this.  Stacking astro images generates
so many files, it would be great to be able to use Digikam to keep track of
them, or at the very least, for Digikam to indicate when the files exist in
a folder.
