Enhanced crop feature to match exact document sizes

[venoll]

Is your feature request related to a problem? Please describe. It's not a problem in the sense of a bug, but the problem is that you can't use the crop feature to crop your documents to an exact size, e.g. A4 (210 x 297 mm). It's especially annoying if it comes up to scan documents, which are printed borderless.

Describe the solution you'd like The best solution would be either to let the crop window show the new size of the image so you can move the faders as you need.

Or to put a dropdown menu where you can select a predefined size like in "page size" as shown in the settings window of the scanner. Then a bordered empty box could appear where you can move it over your document to match it exactly and then crop it.

Describe alternatives you've considered Right now there is no other way than to use other tools. Of course you can select a fitting size in the "page size" setting, but as mentioned above, it's annoying when it comes to borderless printed documents. You will have to try many times until you receive a scan, which does not have nasty black bars on any side of it.
