How PLT and PPM differ in practice

PLT 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.

PLT to PPM Conversion: FAQ

What are PLT files?

PLT is a vector image format representing the HPGL standard language developed by Hewlett-Packard for printing line drawings. HPGL is supported by AutoCAD and other CAD software programs. PLT files represent plotter images that can be printed using a computer printer specialized in vector graphics (called "plotter"), which renders images as lines not as dots.

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.
