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 saves all documents in PDF version 1.6 if changes have been made to the document; if changes have not been made, then the version is unchanged. |
 |
PDF Xpress does not directly support remote file communication protocols, such as HTTP and FTP, to load PDF files. |
