Convert HPGL to VIFF

The HPGL file extension, short for Hewlett-Packard Graphics Language, is a file format and printer control language developed by Hewlett-Packard in 1977 for use with their plotter printers, starting with the HP-9872. HPGL files contain commands that instruct plotters to draw images using lines rather than dots, making them essential in CAD applications and technical drawings. The language uses a series of two-letter codes followed by parameters to control the plotter's actions, such as moving the pen or drawing shapes.

The Khoros Visualization Image File Format (VIFF), developed by AccuSoft Corporation, is a bitmap image format used primarily within the Khoros software environment for scientific and engineering applications. It supports various image types, including grayscale, color, and multi-spectral images, making it useful for visualizing complex datasets. Despite its powerful capabilities, VIFF is now considered somewhat obsolete due to the emergence of newer, more versatile image formats. However, it remains an important part of the history of image processing and visualization technologies.
