Load document from stream Leave feedback

There might be the case when source or target document is not physically located on the disk. Instead, you have the document in the form of a stream. In this case, to avoid the overhead of saving stream as a file on disk, GroupDocs.Annotation provides a way to work with document streams directly. 

The following are the steps to be followed:

• Obtain document stream; 
• Pass opened source document stream to Annotator class constructor.

Following code snippet describes this case.

using (documentStream = File.OpenRead("input.pdf"))
using (Annotator annotator = new Annotator(documentStream))
{
     	AreaAnnotation area = new AreaAnnotation()
       {
       	Box = new Rectangle(100, 100, 100, 100),
       	BackgroundColor = 65535,
       };
       annotator.Add(area);
       annotator.Save("result.pdf", new SaveOptions());
}
