Thereby the PDF content comparer, as the name states, does not do a pixel-based or structural comparison but an element based check for differences in the documents.
The following elements are compared and any differences logged:
These differences each have a configurable tolerance value so that minor differences can be ignored if necessary. For the eye it does not matter whether a line or box is being miss-placed by a couple of pixels, as long the line is there and looks like intended.
For the documentation and on how to use the PDF content comparer tool, please refer to the readme page. You will also find all options to modify PDFCs behavior there.
In addition you can check out the API. The API is also part of the download package.
If you have any questions, problems or suggestions, please do not hesitate to contact pdfc@inetsoftware.de for technical support.
A good example on how i-net PDFC will help is the decision for a reporting tool.
E.g, you're using Crystal Reports but find it to expensive to keep and you're looking for a replacement that is much cheaper but has the same capabilities. And, more important, your old reports look the same after migration to the new system.
Using i-net PDFC you can compare the PDF output of your favorite reporting systems and make an objective decision.
