Unfortunately not,
im.show(command="/opt/local/bin/xv") and im.show(command="/opt/local/
bin/display") both still result in
Another guess is that the X server is not started and show doesn't
know how to identify it. With imagemagick installed, I got the same error
as you, even with Xwindows started. I'm guessing that we are
not interfacing properly with the X server. It appears display has an option
for naming the Xwin

I'm brand new to Sage, and would like to follow the path of least
resistance to playing around with images. I tried to follow these
instructions, but got tripped up.

Tom Boothby, who I think does not read this list, is also working on
improving image manipulation in sage without using the PIL. He is
only using the gd library. Its a work in progress right now though.

Since it's come up several times, it might be worth material fo
yeahr thx, might be interesting for others, yes... just one remark:

i hope it's correct what i say: this command is necessary to pick the
right python installation (the one from sage)

Alright, it wasn't meant in a negative way. I thought there was a URL for
the transition and you'd point me there. But it's alright if you do it like
this :)

the new one is already bigger and better than the old one and things
like this are a good opportunity for feedback. This one e.g. already
includes external
Just a quick remark: since the search is beta, where's the old one?

I think, plotting is not his main problem. He want's to manipulate the
data on a basic level.

Yes, I'm aw
This does not answer your question but might help your friend.
The command matrix_plot (eg, "sage: matrix_plot(random_matrix(GF(389),
10), cmap='Oranges')")
might be a simpler function to use if he just wants to test how good
the linear code works on an "image".
