- Description
- A PPM file is a 24-bit color image formatted using a text format. It stores each pixel with a number from 0 to 65536, which specifies the color of the pixel. PPM files also store the image height and width, whitespace data, and the maximum color value.
- 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.
