The complete reference to these important graphics languages that are supported by many Hewlett-Packard graphics peripherals.
This comprehensive tutorial offers you a complete education in HP-GL/2, the standardized version of Hewlett-Packard's Graphics Language, and HP RTL, Hewlett-Packard's Raster Transfer Language. To help you get the highest quality output from your plotters and printers, this information is broken down into the following sections:
- An introduction to plotting and printing using HP-GL/2 and HP RTL
- HP-GL/2, including descriptions of the kernel and the extensions
- HP RTL, including how to define images, colors, and interactions, and how to transmit data
- Tips on writing efficient programs
- An extensive glossary and index
With this book, you will learn how to make effective use of the coordinate system, scale your data, write device drivers, set colors, and compress raster data.
The book assumes that you have a knowledge of your computing system and familiarity with at least one programming language. All numbers are presented using the International System of Units.
