Save PDF to Memory

PDF Xpress™ supports saving a PDF document to memory.

To save an open PDF document to memory:

Create a new SaveOptions object.
Configure the SaveOptions object.
Invoke the SaveToBuffer method and specify SaveOptions to write the PDF file to a local byte array.
Invoke the SaveToHandle method and specify SaveOptions to write the PDF file to a new Global Memory buffer.

PDF Xpress does not directly support remote file communication protocols, such as HTTP and FTP, to load PDF files.
