[Image-SIG] Can't print or display PSDraw output.

[Richard Townsend]

When I use PSDraw() to generate postscript from an image, I can't print it
or display it in ghostview.

e.g.

import Image, PSDraw
im = Image.open('lena.gif').convert('L')
box = (1*72, 2*72, 7*72, 10*72)
outfp = open('lena.ps','w')
ps = PSDraw.PSDraw(outfp)
ps.begin_document()
ps.image(box,im,72)
ps.rectangle(box)
ps.end_document()

When I try to send 'lena.ps' it to the printer, the print job is aborted.

When I try to display it in ghostview, I get:

Error: /undefined in gsize

Paint Shop Pro also complains about 'undefined in gsize'.


Is it possible to use PSdraw() to print images ?
