Help Locate PDF VCL/ActiveX set to be used in a Delphi application

in Help :: I'm looking for a PDF VCL (or even ActiveX) set with some specific set of features that are not just „creating PDF documents“.

Here's the "requirements list":

• must have: Loading of an existing PDF document.
• must have: Knowing is the PDF is password protected.
• must have: Knowing the PDF version of the document (1.4, 1.5, ...)
• must have: Creating a set of bookmarks / outlines for a loaded document. Bookmarks are „external“ PDF documents. The bookmarks point to other PDF documents using a „relative“ path („../afolder/another.pdf“)
• must have: Inserting a „tree“ of external bookmarks to the existing bookmark tree of the loaded document.
  
  
• nice to have: Extracting a scope of pages from a loaded document, saving as another document.
• nice to have: Saving the loaded document with a different version (something like : „convert“ a PDF document from 1.5 to 1.4)
• nice to have: Extract text data.

Please, if you are a third-party vendor or if you know of such a VCL/ActiveX set, post the link as a comment to this post.

Update 1: Seems like I have found one such library: Quick PDF Library (formerly iSEDQuickPDF). Loading supported. Adding external outlines is supported, security info is supported, version info is supported .. I'm now going to test page/text extraction...
