Saves the document displayed in the GdViewer control in JPEG format to an instantiated Stream object according to what you have specified. The document is saved with full GdPicture/XMP annotation support.

Please consider using the GdViewer.BurnAnnotationsToPage method before saving, if you expect, that your annotations will be included in the document content.

Syntax

public GdPictureStatus SaveDocumentToJPEG( 
   Stream Stream,
   int Quality
)

public function SaveDocumentToJPEG( 
    Stream: Stream;
    Quality: Integer
): GdPictureStatus;

public function SaveDocumentToJPEG( 
   Stream : Stream,
   Quality : int
) : GdPictureStatus;

public: GdPictureStatus SaveDocumentToJPEG( 
   Stream* Stream,
   int Quality
)

public:
GdPictureStatus SaveDocumentToJPEG( 
   Stream^ Stream,
   int Quality
)

'Declaration
 
Public Overloads Function SaveDocumentToJPEG( _
   ByVal Stream As Stream, _
   ByVal Quality As Integer _
) As GdPictureStatus

Parameters

Stream: A System.IO.Stream object where the resulting JPEG file will be saved to. This Stream object must be initialized before it can be sent into this method and it should remain open for subsequent use.
Quality: The compression quality level from 0 to 100 to be used to compress the resulting JPEG file. 0 means worse quality and better compression, 100 means the best quality and worse compression.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.

Remarks

Just to remind you that if you want to permanently incorporate the annotations to be part of the document content, you need to use the GdViewer.BurnAnnotationsToPage method before saving the file.

The output stream should be open for writing and should be closed/disposed by the user as well.
