Remarks

To support reading JPEG2000 and JBIG2 compressed PDF files, you must distribute the Atalasoft.dotImage.Jbig2.dll, Atalasoft.dotImage.Jpeg2000.dll, and AtalaJp2.dll alongside your Atalasoft.dotImage.PdfRasterizer.dll.  However you are not required to distribute these dependencies if you do not wish to support JP2 or JBIG images within PDF files.
