Is the PDF library that Microsoft uses in Excel available to the outside world?

Question

Excel 2010 (and Word 2010, probably others) have the ability to save directly to a PDF:

and they print it without installing a "PDF printer".

Is the PDF library Microsoft is using to generate PDFs available to the outside world?

• a COM object?
• a codeplex open-source project?

tl;dr: How is Microsoft creating PDFs from native Win32 applications?

Answer 1

ABCpdf boasts Microsoft uses their product. Don't know how and where does Microsoft uses it, but it sure seems to be good pdf library.
