Unlike older Kindles, the DX can display PDF
(portable document format) files without prior conversion -- plug the device into a computer with its USB cable, drag and drop PDFs into its "documents" folder, and those files will appear on the DX s home screen.
The start, exchange wiper, list, detail, save CSV/PDF and display PDF
operations are displayed on the toolbar according to the user's procedure.
Version 12 reportedly features the following enhancements: simplified saving of images to memory by providing a method that will return the saved image in a memory object; enhanced extraction features for TIFF documents resulting in faster viewing access; ability to display PDF
documents, including engineering drawings, in vector form; enhanced support for PCL file format, including support of color and grayscale; as well as increased support for MO:DCA and AFP files formats.
