Convert HPGL to EPSI

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.

EPSI, standing for Encapsulated PostScript Interchange, is a file extension used primarily in the printing and graphic design industries. It stores PostScript data along with a low-resolution preview in bitmap format, facilitating the visualization of graphic content in layout applications without needing to interpret the complex PostScript code. Introduced in the 1980s by Adobe Systems, EPSI files serve as a bridge between different software applications, ensuring consistent and high-quality output in various publishing workflows. Their efficiency and adaptability have made them a standard for exchange of graphic data in professional environments.
