Foxit Quick PDF Library does its best to recognize the appropriate image type and save the embedded image as that image type. This can be tricky at times because some image formats such as PNG are not native to the PDF format so they are manipulated and stored in a modified form in the PDF. When this happens you’ll most likely want to save the image data back into the image format that it was originally in before it was added to the PDF. Sometimes it’s necessary to extract images from PDF files and save them to disk.
