Something like this works for me (and doesn't degrade the image as far as I can see): ------------------------------------------------------------------------------------- import pyx from PIL import Image import sys try: jpgfile = sys.argv[1] im = Image.open(jpgfile) except: print "Usage: python pyx-jpg.py JPEGFILE" sys.exit() nx, ny = im.size bm = pyx.bitmap.bitmap(0, 0, im, width=nx*pyx.unit.x_pt, height=ny*pyx.unit.x_pt) c = pyx.canvas.canvas() c.insert(bm) c.writetofile("pyx-jpg-test.pdf") ---------------------------------------------------------------------------------------- Cheers Will -- Dr William Henney, Centro de Radioastronomía y Astrofísica, Universidad Nacional Autónoma de México, Campus Morelia -- Dr William Henney, Centro de Radioastronomía y Astrofísica, Universidad Nacional Autónoma de México, Campus Morelia ------------------------------------------------------------------------------ Ridiculously easy VDI.
