Commercial Enterprise Quality
- Accuracy
- Performance
- Robustness
Support for PDF Documents
- Full integration with the Adobe© PDF Library
- In PDF documents, the document content is not necessarily stored according to reading order. DeltaFinder can restore the reading order of the document content. Comparison engines, that cannot restore reading order, produce awkward comparison results.
- Support for WORD and OpenOffice documents will be added in Q4 2009.
- Support for comparing source documents to scans for quality assurance measurements in print production will be added in Q4 2009.
Intelligent Context Detection
- High quality change detection reduces false positives.
- Moved text can be detected as non-change instead of a pair of distinct deletion and insertion.
Text and Image Comparison
- DeltaFinder can perform text comparison and image comparison.
- Image comparison is used for identifying logos and for controlling technical drawings.
Barcode Detection
- DeltaFinder can detect and compare a range of 2-dimensional and 1-dimensional barcodes.
Regions of Interest
- Define matching regions of interest for comparison, for example: header, footer, body.
- Confine the comparison to a specific region of the document.
