[digiKam-users] Update thumbnail/preview after editing image in an external raw processor

[AndriusWild]

Hello,

Is digikam supposed to update thumbnail and preview for a image edited in RawTherapee/ darktable / ufraw via the new plugin interface?

As at least Darktable stores only the instructions of the edit, and not a new
image or thumbnail (outside its own database), I don't see how Digikam can
provide a new thumbnail.

Note that an exported image is not the same file as the original.

Hello;

When I edit in an external program I create a jpg then use Exif to overwrite the jpg stored in the raw file. In my case I use Nikon so with Darktable the export parameters are:

same file name with_J4R appended, jpg 8 bit, quality 100, max size 3873 x 2592. Upscaling no. 

The exif command is 

exiftool "-JpgFromRaw<=%%d%%f_J4R.jpg"    -ext NEF -r

If you want it operate recursively add a space then a period after the -r

This at least shows me what the revised photo should look like even in Digikam.

Regards

Sher
