What makes PDFTextStream different from open source libraries?

This goes back to why PDFTextStream is priced the way it is. We believe that PDFTextStream offers significantly more overall value due to the levels of accuracy, performance, and support that it delivers, even in light of its pricing.

If your project does not require the highest degrees of these qualities, then you will likely find one of the open source libraries acceptable.

In addition, we also offer consulting and custom development services that yield PDFTextStream-based solutions to tackle the most difficult and mission-critical content and data extraction problems. If you have such a problem, and wish to tap the expertise and experience we bring to these efforts, then using PDFTextStream is mandatory -- we simply could not accomplish what we do if we were to use any other library.
