Hi,
I'd like to crop a bitmap image. How? This is my code for image inclusion:
-------
\directlua{
  image = img.scan{filename="hacker.jpg"}
  tex.box[0] = node.hpack(img.node(image))
}
\box0
-------
bbox{...} seems to work only with PDF images.
use the pdf clip operator i.e. set a path with 'l' and 'm' and then apply the operator 'W n'
where?

I mean, what is a good place to put the pdf instructions?
