screenshot of DigiKam thumbnail view showing .FITS previews

SUMMARY

Maybe I'm missing some fundamental understanding of how DigiKam works, I am assuming because the ImageMagick plugin is loaded (Help -> Component Information) it should be able to read/write .FITS files?

However, I can't get a preview image of a .FITS file, or open in editor. Both show checker board pattern, however the Colors tab shows histogram, which means(?) it sees something in the image file? I also had to add .FITS to Settings -> Views -> MIME types. (see attached screenshot)

I also installed ImageMagick-7.0.11-5-Q16-HDRI-x64-dll to see it it would help.

Can you share some file samples somewhere in the cloud to try to reproduce the dysfunction ?

I played with FITS on my Macbook pro using Chandra radio telescope samples :

Image magick version used to compile under MacOS is 6.9.11, but under Windows version 7.X must not be a problem.

I suspect a specificity with your FITS images not very well supported by Image Magick which render an alpha layer image. FITS is a very complex container with plenty of features.

We need samples from your collection to investigate.

Comment 3 Maik Qualmann 2021-04-02 05:39:52 UTC

I suspect a change or bug in ImageMagick-7.x. Here under my native digiKam version I only see colored areas or pixel strips.

MAik, in the Chandra Fits collection, i found one item which render alpha layer thumbnail :

... but if i force to render thumbnails again and again, i can see that item is properly view, and sometime, not...

MAik,

This is the console output when i force to rebuild thumbnails with F5. At this time 2 item have been generated with alpha layer :

Comment 6 Maik Qualmann 2021-04-02 07:00:17 UTC

This image as an example: m51_optical_B.fits
It is displayed as a pink thumbnail for me, the preview is empty. With the "display" command from ImageMagick I get a correct image. Nothing noticeable in the debug log.

Comment 7 Maik Qualmann 2021-04-02 07:05:19 UTC

With the AppImage from digiKam-7.2.0 and the internal ImageMagick-6.9 I get a correct image of the example image.

Comment 9 caulier.gilles 2021-04-02 08:33:10 UTC

Maik, 

I found a way with ImageMagick to extract all recognized metadata from image. For FITS this give something like that:

[gilles@localhost FITS]$ identify  -format '%[*:*]'  ngc6543_optical_B.fits 
date:create=2021-04-02T08:19:47+00:00

I think we will need a new DMetadata wrapper based on ImageMagick as existing ones based on libheif and libraw...

In opposite of 'identify -verbose filename' which take age to give output as histogram and color spaces are parsed, the 'identify  -format '%[*:*]' filename' way is very fast...

I reopen this file for non Exiv2 supported file and metadata extraction :

First, I want to thank everyone for the Very quick action on this! Wow

I can somewhat follow the discussion, but I'm not sure if the .FITS issue is fixed, although this Bug shows a Status of Resolved Fixed. I downloaded and installed the weekly snapshot, digiKam-7.3.0-20210401T190948-Win64.exe, but I'm still getting the same results:

Thumb + Preview images show checkerboards while Colors tab show histograms. The Image Editor shows nothing (no checkerboard) however the cursor changes from an arrow to a plus sign + like is was moving from an empty area to the image.

I was asked to include some FITS images. The first 2 are raw (uncalibrated) 16bit images from my 2 CCD cameras. The second 2 (with _out in filename) are calibrated (dark + flat) and 32bit.

The fix done by Miak in source code have been done... today.

The daily build is updated in the evening (Paris time), so you must wait tomorow morning (:-)))...

Best

I have tested the 4 images with my Linux digiKam developer version and they are all displayed correctly.

Ha! another example of how coders make (almost) everything work in the world and always come first :)

Comment 15 Basil Rowe 2021-04-04 18:49:31 UTC

Just installed digiKam-7.3.0-20210404T081036-Win64.exe. After rebuilding the thumbnails (which took a while for about 23,000 images (1.5 years of chasing asteroids, trying to figure out rotation periods) the thumbs and images are all there!

Many, many thanks to all!
