Saves the document displayed in the GdViewer control to a file in JPEG format on a distant server using HTTP or FTP transfer according to what you have specified. The file transfer will be run synchronously. 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.

The GdViewer.DataReceived event is raised to allow you to monitor the transferred data. Likewise, the GdViewer.TransferEnded event is raised right after the transfer will finish. You can also control displaying the progress bar by enabling or disabling the GdViewer.EnabledProgressBar property.

Public Overloads Function SaveDocumentToJPEG( _
   ByVal Uri As String, _
   ByVal Login As String, _
   ByVal Password As String, _
   ByVal Quality As Integer _
) As GdPictureStatus

Parameters

Uri: The full URI path with the full document name, where the resulting JPEG file will be saved, for example ftp://ftp.gdpicture.com/upload/myfile.jpg or http://www.gdpicture.com/upload/myfile.jpg.
Login: The login required to authenticate on the server. It can be an empty string.
Password: The password required to authenticate on the server. It can be an empty string.
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.

Use the GdViewer.GetLastTransferError method to diagnose the error if this method has failed with one of the GdPictureStatus.Internet... errors.

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.

Both the GdViewer.DataReceived event and the GdViewer.TransferEnded event are raised to allow you to monitor the transfer progress.
