In my tests with PDFs that have Tiff images when I extract the Tiff image, the saved tiff has a different resolution. I've attached 300x300.tif, which is my source tif. Then it's converted to the PDF 300x300.pdf. Then I attempted to extract it to 300x300_extracted.tif. I'm having weird issues with the resolution being maintained as well as the color. The background should be write, but the extracted TIF is black.
