pdf-dicer v0.4.4

PDF-Dicer

Split PDF files into many based on barcode separators.

This is useful if scanning a large number of documents in a batch (e.g. via an automated office scanner) which then need to be split up again.

PDF-Dicer takes a single PDF file made up of multiple scanned documents. Each sub-document has a starting and ending barcode.

PDF-Dicer takes this file, splits on each barcode set, validates the barcodes and outputs back into individual files.
