OCR for PDF Stream

IronOCR also supports Stream.

In this example, IronPDF is used to create a PDF Stream that can later be used for text recognition by IronOCR.

Please note that IronOCR supports reading Stream as an input, and can also export results to a Stream, for example via SaveAsSearchablePdfStream.
