Description kdebugs 2019-08-17 15:07:26 UTC
SUMMARY

It would be great to have support for rendering Affinity Photo (AFPHOTO) file thumbnails.  These files have an embedded JPG preview which can be used in lieu of trying to process a proprietary format.

Do you want the files on this posting or on 389194?  I can post a couple of samples for testing with.

On this file it's fine as it's about AFPhoto format specific

I take a look about AFPhoto format, and it's a proprietary Raster image, similar than PSD for photoshop.

The most important software component to be able to extract preview is Exiv2. We use this library in digiKam. So reporting this wish to Exiv2 team will be a plus.

Sample AFPHOTO file

Simple JPG opened and re-saved into Affinity Photo's proprietary AFPHOTO format.
Comment 7 kdebugs 2019-08-17 21:33:52 UTC
I have posted a request with Exiv2 as well: https://github.com/Exiv2/exiv2/issues/986
Comment 8 caulier.gilles 2019-08-18 10:41:45 UTC
I seen the file in Exiv2 quickly closed.

There is also another possible to ask to ImageMagick if a loader is under development to support this raster format. digiKam as a delegate image loader using Image Magick to support exotic image formats.

You can try to make a wish in ImageMagick bugzilla:

For proprietary image formats, we cannot add thumbnails support. We have already plenty of format support through plugins, and especially one using ImageMagick.

If a new proprietary format must be supported, this must be done trhough ImageMagick, not digiKam directly. 

So report this problem to ImageMagick project.

Best Regards
