This method converts and saves the currently loaded document to an instantiated stream object according to what you have specified. The output format is SVG.
Only the first page within page range is converted.
Syntax
Parameters
- Stream
- A stream object where the current document is saved to as a SVG image. This output stream must be initialized before it can be sent into this method and it should stay open for subsequent use.
If the output stream is not opened for both reading and writing, the method will fail returning the GdPictureStatus.InvalidParameter status.
Return Value
A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.
Example
Converting and saving a PDF document to a SVG image file using a stream.
Using gdpictureDocumentConverter As New GdPictureDocumentConverter()
Dim status As GdPictureStatus = gdpictureDocumentConverter.LoadFromFile("drawing.pdf", GdPicture14.DocumentFormat.DocumentFormatPDF)
If status = GdPictureStatus.OK Then
Dim oFileStream As New System.IO.FileStream("drawing_stream.svg", System.IO.FileMode.Create)
status = gdpictureDocumentConverter.SaveAsSVG(oFileStream)
If status = GdPictureStatus.OK Then
MessageBox.Show("The file has been saved successfully.", "GdPicture")
Else
MessageBox.Show("The file has failed to save. Status: " + status.ToString(), "GdPicture")
End If
oFileStream.Dispose()
Else
MessageBox.Show("The file has failed to load. Status: " + status.ToString(), "GdPicture")
End If
End Using
using (GdPictureDocumentConverter gdpictureDocumentConverter = new GdPictureDocumentConverter())
{
GdPictureStatus status = gdpictureDocumentConverter.LoadFromFile("drawing.pdf", GdPicture14.DocumentFormat.DocumentFormatPDF);
if (status == GdPictureStatus.OK)
{
System.IO.FileStream oFileStream = new System.IO.FileStream("drawing_stream.svg");
status = gdpictureDocumentConverter.SaveAsSVG(oFileStream);
if (status == GdPictureStatus.OK)
{
MessageBox.Show("The file has been saved successfully.", "GdPicture");
}

}
oFileStream.Dispose();
}
else
{
MessageBox.Show("The file has failed to load. Status: " + status.ToString(), "GdPicture");
}
