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

Third-party generated PDF files may house multiple images, text, or annotations in a single PDF page. As these elements must be rendered within the Dynamic Web TWAIN, it will utilize the PDF rasterizer addon.

When importing a PDF file generated by Dynamic Web TWAIN, or if each page of a third-party PDF holds nothing but a single image, there’s no need for the PDF rasterizer addon.

If you need to append images to an existing PDF and want to keep the original pages instead of rasterized images in the saved PDF, you need to enable the preserveUnmodifiedOnSave property.
