The Open method opens a PDF, Postscript, XPS, or image format like TIFF, PNG or JPEG, files from any .NET stream. The Open method reads all the file contents into memory and closes the file right-away. The OpenEx method opens each page as it is requested, keeping the file handle open. OpenEx has the advantage of being more efficient but prevents other applications from writing to the file while it is being viewed.
Public Function Open(stream As System.IO.Stream, pwd As String) As Boolean
public bool Open(System.IO.Stream stream , string pwd)
stream
.NET stream object containing the PDF or XPS document
pwd
Password to use if document is protected.
Returns True if document opened successfully, False otherwise.
The exception Amyuni.PDFCreator.IacException.LicenseKeyError might be generated if the provided license is not valid or wrong.
To check if a document is protected and ask the user for the password, you can use the following example.
Member of Amyuni.PDFCreator.IacDocument.
