PDFTextStream is a Â PDF content extraction library for Java and .NET(in fact, the .NET version is compiled with IKVM).
PDFTextStream is similiar to PDFBox(Open source), but it is a commercial product, could not be used free before v2.6.
Compare to PDFBox, another difference is Â PDFTextStream is much faster than PDFBox( I got the report from the home page of PDFTextStream without testing).
Because of the realities of the economics around developing and maintaining a product like PDFTextStream, its pricing has often been out of reach of many projects and very small organizations that really need high-quality PDF content extraction functionality. Thatâ€™s not to say that PDFTextStream is overpriced â€” itâ€™s actually less expensive than other options â€” but that is small comfort to many that simply cannot afford or cannot justify the expenditure yet.
This change should fix that: if you have a smaller project, are working on a startup, are involved in information research, etc., you can now benefit from all that PDFTextStream has to offer.
