Is it cropping out a whole page of a passport?
Is it cropping out perhaps a photograph? - that is popular
Do you want to size and crop an existing portrait suitable for a passport image?
...or anything else...
When it comes to the crop tool, the preset guides are really meant for photographers wanting to compose their work with emphasis on certain sections of the image. hence the rule-of-thirds, golden section etc. Probably the only one that might be applicable is the center-lines.
There are other ways than the crop tool to trim an image to size. Back to what is the purpose.
If you can post an example, even better.
(Out of interest, do you really use Windows and Linux and OSX as operation systems? )
I think the OP wants something that s/he can align with the nose/mouth/eyes of the subject to generate a crop with the rather stringent rules of
passport photography.
If I were to do such a thing, I would create a path that I would import in the picture (one keystroke with the proper script), then align over the layer (possibly scaling the layer or the path), and then use specific points in the path to crop the layer (another single keystroke with the proper script).
If a specific final size in pixels is requested then one can use fixed guides, and therefore use ofn-preset-guides to generate & load a custom set of guides.
