inverse selection for a keyword

[BSPicture]

Initial situation:
- There are 5 images with a church
- 4 of them are marked with the keyword "church".
- in one image with a church the keyword "church" is missing.

Two things have to be checked
a) if all images tagged with church really show a church
b) Whether all images showing a church have the keyword "church".


Check a) Do all images marked with the keyword "church" really show a church? This one is easy

Check b) Do all images with a church have the keyword "church"?
How to do this?
I need some kind of reverse selection: When you click on the keyword "church" all images that are not tagged with "church" are highlighted/selected.
This would allow to mark the images with the missing keywords afterwards.

Should look something like this:

Second time within a short time that a user asks for a "not assigned to category <category>" query. In XnView MP 1.3.0 this is not possible - but perhaps it's a good idea to add this. A simple start would be to inverse complete query when using "NOT". But I guess what is really needed is that "not" can be applied per category/keyword. This way you can search for images that are assigned to "chapel" but are not assigned to "church".

Hi Hartmut, thanks for the info anyway. It saves me from further trials and experiments.
Implementing an inversion of the search result in a later version of XnView would be very helpful to check assigned keywords for plausibility and completeness.
