HPGL to PPM: what carries over and what does not

HPGL describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the PPM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

HPGL to PPM Conversion: FAQ

What are HPGL files?

The .hpgl file format (Hewlett-Packard Graphics Language) is a text-based vector format used to control plotters and printers. It contains simple ASCII commands that direct pen movements to draw lines, curves, and text. Originally created for HP plotters, it's widely used in CAD, engineering, and PCB design for precise technical drawings. Its simplicity and compatibility keep it relevant in many design and printing workflows.

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.
