The HPGL file format, standing for HP Graphics Language Plotter File, is a specialized file type developed by Hewlett-Packard. It is primarily used for controlling plotter devices, which are printers that draw images with lines instead of dots, making them ideal for engineering and architectural drawings. HPGL files contain a series of two-letter instruction codes followed by parameters that direct the plotter's drawing operations, such as moving to a point, drawing a line, or selecting a pen.
Better Portable Graphics (BPG) image format created to replace the JPEG format; provides the same quality as JPEG images but in a smaller file size; supports lossless compression; natively supports 8 to 14 bits per channel.
