XISF Image-Format in Ekos, Unknown 'ColorFilterArray' Element in PixInsight was created by Juergen_from_Bavaria

Using current Indilib, I took some 16Bit Raw XISF - Images for testing and did preprocessing with WBPP in PixInsight afterwards.

With CFA Option in PI, WBPP cancels execution @ Image Registration.

Deselecting CFA in WBPP (-> Grayscale) processing goes through to the end. In both options WBPP shows a Warning: ** Skipping unknown 'ColorFilterArray' element. (line=4 offset=3025)

Wrong usage or bug?

Thank you. Yes this is bug because that element is not child of <Image> element but root <xisf> one. Even thought the specification allows that but even PixInsight doesn't implement spec 100%.

Jasem I pushed fixed version will it propagate or did you version locked it?

Fixed version of libxisf should now be now in stable ppa. Nightly should be updated in few hours. So try to update it and report back if it works.

Hi,

I updated all systems and did a daylight test with my ZWO ASI533 MC Pro (OSC):
- selected both Raw16Bit and Raw8Bit - XISF as image format in Ekos and took some frames
- after opening in PixInsight no warning "Unknown 'ColorFilterArray' any longer
- after debayering I got RGB Frames in PI w/o errors

Seems to work now!

I will test it on the stars and report asap as soon as we have CS here.

Thanks a lot for your work!

Best,

J.

I also did a quick test with Altair Astro 26c and had no issues opening Color frame in pixinsight. Checked header and Bauer matrix was reported correctly also.

So I managed to get a couple of hours last night on the Pac-Man nebula. All shot with xisf format the only issue I had was the camera restarted due to a timeout mid sequence and the first frame post restart was saved as a fits file. After that it went back to xisf. I have ran WPBB in PI with these files and all debayered without issue.

Yesterday I shot XISFs to get a mosaic of M13 region. Pre- and postprocessing with PI worked without errors.

Thanks again!
