Convert PDF to TIFF #513

Do you have any example which converts multiple PDF pages into multi-page TIFF ?

Your best bet is probably to use a pdf lib/tool that's specifically designed for it.

You can use pdfium C# wrapper to get content from PDF and directly convert to them to TIFF. I currently use below library to convert PDF to PNG and do the OCR https://github.com/GowenGit/docnet

Look at the OCR PDF in .NET article. It describes how to OCR PDF using Docotic.Pdf and Tesseract.

Pure PDF to TIFF conversion does not relate to Tesseract at all. Tesseract is for optical recognition only.
