Using "jpegtopnm" from Netpbm suite. Input is a JPEG file and result (the PPM file) is sent to stdout. The procedure "readPPM" reads directly from the stream and build the image container.
<lang Nim>import bitmap
import osproc
import ppm_read
import streams
# Launch Netpbm "jpegtopnm".
# Input is taken from "input.jpeg" and result sent to stdout.
# We need to specify "options = {}" as by default stderr is redirected to stdout.
let p = startProcess("/usr/bin/jpegtopnm", args = ["input.jpeg"], options = {})
let stream = FileStream(p.outputStream())
let image = stream.readPPM()
echo image.w, " ", image.h
p.close()</lang>
