Load document from stream

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.

String outputPath = "LoadDocumentFromStream.pdf";

InputStream stream = new FileInputStream("input.pdf");
final Annotator annotator = new Annotator(stream);

AreaAnnotation area = new AreaAnnotation();
area.setBox(new Rectangle(100, 100, 100, 100));
