If you are scanning a document, with many pages, you do not lower the scanner lid (to speed up scanning), but this causes a black stripe to form at the edges of the text. Now you can select the text and images excluding the black border; If you want to obtain a document with the same format, for example an A5 (without black borders) this is not possible with this program, because if you report it in A5 format, the black border is revised. It should be easy to delete the outside of the selection. Sincerely
