C# Class PdfSharp.Drawing.XPdfForm

Represents a so called 'PDF form external object', which is typically an imported page of an external PDF document. XPdfForm objects are used like images to draw an existing PDF page of an external document in the current document. XPdfForm objects can only be placed in PDF documents. If you try to draw them using a XGraphics based on an GDI+ context no action is taken if no placeholder image is specified. Otherwise the place holder is drawn.

Public Methods

Method	Description

FromStream ( Stream stream ) : XPdfForm	Creates an XPdfForm from a stream.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Frees the memory occupied by the underlying imported PDF document, even if other XPdfForm objects refer to this document. A reuse of this object doesn't fail, because the underlying PDF document is re-imported if necessary.

Private Methods

Method	Description
Finish ( ) : void	Sets the form in the state FormState.Finished.
XPdfForm ( Stream stream ) : System	Initializes a new instance of the XPdfForm class from a stream.
XPdfForm ( string path ) : System	Initializes a new instance of the XPdfForm class from the specified path to an external PDF document. Although PDFsharp internally caches XPdfForm objects it is recommended to reuse XPdfForm objects in your code and change the PageNumber property if more than one page is needed form the external document. Furthermore, because XPdfForm can occupy very much memory, it is recommended to dispose XPdfForm objects if not needed anymore.
