Post Script Code for Grey-Scaled Displays

摘要

PostScript is a versatile page description language used for the production of complex images combining graphics and text information. The note describes a PostScript program capable of producing a detailed grey-scaled image of information represented by a series of hexadecimal codes. A parameter section is included in the PostScript code that allows the user to modify the appearance of the diagram without the need to re-execute the program that generated the data and/or PostScript file in the first place. The code can be used on many different systems that support a PostScript printing device, but was originally intended to be printed on a 300 dot per inch laser printer. The PostScript code contains procedures to create time strings in hours, minutes, and seconds format from an input value in decimal hours.
