I downloaded your PDF toolkit. My first impression is favorable. It does what I am looking to achieved and the examples are self explanatory.
What I want to do is customized pdf files, possibly very large files, on the fly. Fill forms and insert images on the fly. Basically the input pdf file is used as a template to generate a second set of PDF file.
My only reservation is in your overview it states: "Aspose.Pdf.Kit is a non-graphical PDF® document manipulation component that enables either .NET or Java developers to manage existing PDF files or manage form fields embedded within a PDF files."
Is the PDF toolkit developed using Java? Do you have any performance metrics of the toolkit? How well does it handle very large PDF files?
