Load document from InputStream 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 InputStream. In this case, to avoid the overhead of saving InputStream as a file on disk, GroupDocs.Merger provides a way to work with document streams directly. 
The following are the steps to be followed:

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

Following code snippet describes this case.

try {
    InputStream stream = new FileInputStream("c:\\sample.docx");
    Merger merger = new Merger(stream);
    System.out.print("Document loaded from stream successfully.");
} catch (Exception e){
    throw new GroupDocsException(e.getMessage());
}
