PreView Client Viewer is designed to work with DPK, PBMGZ, PPMGZ, and tif (black, white, and colour) files to allow the user to create LAS, LIS, and DLIS files from the DPK format. PreView also helps create client plots in their entirety for viewing on the screen and printing. It allows one or more image files of any length to be viewed side by side and allows the images to be annotated or manipulated. It has been tested with: Vista (32-bit & 64-bit platforms), Windows 7 & 8 and includes a concise Help file. Support for Windows XP has been removed.
