PDF to PDF Compare Solution

The Antenna House Regression Testing System was originally developed for our own internal testing of comparing different versions of our software.

Antenna House once used Adobe software to compare PDF outputs, but we weren’t satisfied with the false positives these comparisons generated. We knew we needed a better document comparison platform, so we created our pixel-by-pixel visual comparison system to reduce false positives and find differences that can be hidden in code comparisons.
