DocBridge Delta: Getting Straight to the Point of Document Comparison

For files not identical at the bit level, it is difficult to determine if in fact the content and layout of the file is identical, even when they have the exact same file size and name. In this situation the document objects defined in the file together with their attributes need to be analyzed and, if they are formatted differently, in such a manner that the formatting specifics of similar objects are not taken into account. This is precisely the problem that DocBridge Delta solves, either by displaying the differences visually, or by producing a list of the differences.

Summary

• Comparison of documents or varying formats – particularly for large production jobs
• Visual difference representation down to the pixel level
• Detailed listing of differences at the object level
• Provision of return codes for automatic processing
• Adjustment of the document for comparison in which all the pages are not correctly aligned
• Comparison suppression of specified pages to allow for the processing of documents which for example contain empty pages
• Page areas containing dynamic data such as addresses or the date can be excluded from the comparison
• Checking the consistency of meta information such as indexes in TLE’s in AFP documents
• Available for all commonly used operating systems

Fundamental Technical Process

DocBridge Delta uses the capabilities of the DocBridge Engine to analyze the detailed structure of coded objects in the document files, to convert them to a format independent meta format. Since it can process the most common document formats, it is capable of translating even the most varying document formats into a common object structure in the meta format. At the same time DocBridge Delta can compare both input documents and identify the differences object for object.

Typical Usage Scenarios

This makes DocBridge Delta particularly suitable for users of high-volume production jobs who have converted a given document to another format with the help of an application and want to check if the content and its presentation still correspond to the original. The result can be important in terms of quality control, depending on the goal to be achieved with respect to the presentation as well as the object type or resources used internally.

Supported Formats

DocBridge Delta can compare documents with the same or different input formats. The following input formats are optionally supported:

Mixed Object Formats

• AFP (incl. AFP line and mixed mode)
• ASCII/EBCDIC linemode
• PCL
• PDF
• SAP GOF (Generic Output Format) with formatted OTF (Output Text Format) and ALF (ABAP list format)
• LCDS (DJDE)
• Metacode (DJDE)
• SVG
• Prescribe (as of the 4th quarter 2006)

Raster Formats

• BMP, GIF, IOCA, JPEG, PCX, PNG, TGA, TIFF
