To print the documentation use the printdoc batchfile by typing printdoc. This will implement the command . It is assumed that your printer is attached to lpt1. Otherwise read HPGLUTIL.DOC into a word processing program as an ASCII file, and reformat it as you like before printing. U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY HPGLUTIL, A COMPUTER PROGRAM FOR PROCESSING HEWLETT-PACKARD GRAPHICS LANGUAGE (HPGL) FILES AND REGISTERING PLOTS TO BASE MAPS by Van S. Williams and Gary I. Selner Open-file Report 94-284 Last revision October 4, 1994 SUMMARY HPGLUTIL (version 1.0) is a program for IBM PC and compatible microcomputers that will read HPGL plotter command files for a drawing and transmit the commands to various types of output devices. It will optionally rescale the drawing and transform the coordinates. A drawing may be registered to a basemap mounted in the plotter by using a digitizing sight to identify three registration points marking the upper left, lower left, and lower right corners of the drawing. The program will also change the size of the plot without registration, for example, a D-size plot may be reproduced on a page-size laser-jet. Pen color, width, and gray tone can be set for output to some raster devices. Requirements: IBM-PC (or compatible) running MS-DOS version 2.1 or later with at least 512K bytes of memory, and an output device such as a plotter that supports the Hewlett-Packard Graphics Language. If it is desired to register the plot to a preprinted paper or film base, the plotter must have the capability of digitizing locations on the base. Contents of the release disk: The release disk for report OF 94- 284 (DOS DS HD 3 1/2 inch format) contains all of the files necessary to install and execute the program. In addition, it contains examples of HPGL files for the user to examine and to test the program. A list of the files on the release disk follows: README.DOC text file describing how to print documentation. HPGLUTIL.DOC contents of this documentation. HPGLUTIL.EXE program executable.
