JLS to PLT Conversion: FAQ

What are JLS files?

JPEG-LS .jls is a lossless (and optionally near-lossless) image-compression standard that uses the lightweight LOCO-I predictor plus context-adaptive run-length coding to capture local pixel correlations with very low complexity. It typically delivers higher compression ratios than baseline JPEG while decoding quickly and requiring little memory, making it well-suited for medical, scientific, and embedded imaging where exact pixel fidelity and minimal latency are vital.

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.
