Management Summary

dydocontrast is an application that enables the textual comparison of PDF files. One of the main requirements for many migrations between different output management systems is that the documents in the new application generate the same content as the old documents. The different formatters almost always render the texts differently despite having the same fonts, so that a pure pixel comparison would result in a difference (delta). It is not uncommon for the new document generator to create page breaks that did not exist in the old system. However, the content of the text must be the same.

Based on this requirement, dydocontrast offers the following functions:

Comparison

Identical texts that were output differently due to hyphenation are not output as a delta
Different page breaks do not lead to a delta if the texts are the same
Certain areas on a page can be excluded from the comparison
Specify page groups that can be defined using search patterns.
Comparison of only certain page groups
Configuration of various comparison profiles via JSON files
Automatic recognition of multi-column text
Automatic recognition of tables
OCR recognition and subsequent text comparison of scanned text / text stored as graphics within a PDF.

Batch processing

Mass comparison of file pairs that are specified using a file list
Mass comparison of file pairs that are determined using metadata (XMP), e.g. via the same document ID
Mass comparison of documents in large batch PDFs, in which the document pairs are determined using specific texts in defined page groups.

Report

Marking the deltas in the reference and candidate document
Batch report on all file comparisons
Detailed report on deltas with page and file details

Graphical admin and user interface

Individual comparison of file pairs
Mass comparison of files with administration of job queues
Configuration of page types, profiles, user administration
