I'm looking for a PDF developer SDK to use with C++ in my application. I'm looking for a PDF library that meets these requirements:

• Create PDF documents programmatically
• Manipulate PDF documents (add and remove bookmarks, add links, insert metadata, etc)
• Manipulate pages in a PDF (delete pages, insert pages, reorder pages, etc)
• Add, fill and retrieve information from form fields in a PDF form

Do you have any recommendations on which PDF SDKs I should evaluate for this project?

(Btw, add each of your recommendations as a new answer so that everyone can vote on their favorite SDK instead of having multiple answers with the same recommendation.)
