Load document from Stream Leave feedback

There might be the case when your 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.Signature enables you to work with document from streams directly. Please be aware that Signature object does not dispose passed stream.

The following are the steps to be followed:

• Obtain document stream;
• Pass opened stream to Signature class constructor.

Following code snippet serves this purpose.

using (Stream stream = File.OpenRead("sample.pdf"))
{
    using (Signature signature = new Signature(stream))
    {
        QrCodeSignOptions options = new QrCodeSignOptions("JohnSmith")
        {
            EncodeType = QRCodeTypes.QR,
            Left = 100,
            Top = 100
        };
        // sign document to file
        signature.Sign("SampleSigned", options);
    }
}
