Solutions for handling HPGL (.PLT) plot files.

The HPGL file format is a vector format developed by Hewlett Packard for driving plotters. The file extensions used include .plt, .hpg, .hp2, .pl2 and sometimes .prn. However the use of the .prn extension is not an absolute indicator that the file contains HPGL code. They are often referred to as 'plot files'. Trix Systems offers several options for handling HPGL and the later HPGL2 file formats.
