Document Comparison Objects
Important! Document Comparison API is temporarily not supported. We are working on restoring it as soon as possible.
ABBYY FineReader Engine provides the Comparator object to compare the original document or the page with their copies and find the differences; you may highlight them for the operator performing manual verification or save the comparison results for the long-term storage or demonstration when discussing alterations.
Other objects in this section contain the methods to get these changes and export the comparison results to a file of the specified format.
This section contains descriptions of the following objects:
- Comparator
- ComparisonParams
- ComparisonResult
- Change
- Changes
- ChangeLocation
