When do I need PDF Rasterizer Addon? Can I load existing PDF files into the Dynamic Web TWAIN SDK without the PDF Rasterizer addon?

When you load/download a text-based PDF onto the viewer, you need the PDF Rasterizer Add-on. To detect whether a PDF file is text-based or not, you can use the API IsTextBasedPDF.

Existing PDF files that are image-based can be handled by default and will load without the add-on.

Note that PDF Rasterizer also works when you drag and drop the PDF file to the viewer.
