Question:
Hi, is there a way to make Tesseract.net work with streams rather than files on disk?
My scenario is converting images that are stored in Azure blob storage and I would like to avoid downloading them to disk in order to convert them to PDF.

Answer:
​Yes, of course.
You can use the ProcessPage method in order to achieve this goal.
​Please look at following example:
Code:

var api = OcrApi.Create();
api.Init(Languages.English);
​using (var renderer = OcrPdfRenderer.Create(@"d:\0\output_pdf_file", @"tessdata"))
{
	renderer.BeginDocument("document title");
	foreach (Stream stream in streamCollection)
	{
		var bmp = Bitmap.FromStream(stream) as Bitmap;
		using (var pix = OcrPix.FromBitmap(bmp))
		{
			api.ProcessPage(pix, null, 0, renderer);
		}
	}
	renderer.EndDocument();
}

Hi Is it possible to save the result pdf (from the code above) to a filestream instead of saving it to disk?

Thanks in advance for your reply.
