single_finder

Introduces an overlay (a frame on top of the live view) for users. The finder can be made to fit standard document sizes like A4 or US Letter. You can also configure the expected aspect ratio yourself. For example, you can define an aspect ratio of 3:2, 1:1, etc. as a requirement for auto-scanning and auto-cropping. You can also configure the finder to use a full stroke or a cornered style. Other than the overlay, the functionality is the same as Single-Page Scanning mode.
