Load document from stream Leave feedback

You can load a document from a stream without saving it as a file on a disk. You can use this feature to load a document from different sources like a URL, FTP, and so on.

To load a document from a stream, follow these steps:

1. Implement a method to get the document stream.
2. Call the Viewer class constructor. Specify the method implemented in the previous step.

The following code snippet shows how to load a document from a stream:

from groupdocs.viewer import Viewer
from groupdocs.viewer.options import HtmlViewOptions

def load_document_from_stream():
    # Open document stream
    stream = open("sample.docx", "rb")

    # Render a document from the stream.
    with Viewer(stream) as viewer:
        options = HtmlViewOptions.for_embedded_resources("page_{0}.html")
        viewer.view(options)

if __name__ == "__main__":
    load_document_from_stream()
