HGL to PPM Conversion: FAQ
What are HGL files?
HGL files are the vintage blueprints of the digital world - they're the instructions that old plotter machines used to follow to draw technical designs with actual pens. Developed by HP for their plotters, these files tell the machine where to move, when to lift the pen, and what lines to draw. While they were big in the 80s and 90s for engineering drawings, today you'll mostly encounter them when digging up old project files or working with specialized equipment. The good news is you can easily convert them to modern formats using current software, which is handy whether you're preserving old designs or updating them for new uses. They're like the cassette tapes of the design world - outdated, but still containing valuable content you might want to preserve.
What are PPM files?
PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
