Hi Patrick,
I've been running your script trying to use the command-line
arguments, and something's happening with the format argument. I
specify it with an argument, but then I still get prompted for
format. I might not be doing the flag right. I've tried it with
-f=jpeg, -f=JPEG, -fJPEG, and I think that's it. I'll copy the
terminal output below so you can see. On this example I use -fGIF and
while it doesn't make the script fail, it does still ask me for a
format. Am I specifying the format wrong?
it would have to be the same as the input from the command line, i.e.
-f=jpeg or -f=gif---I don't have a clue why it would fail, though with
our weird crossing of versions I don't know which version you're using.
I put a version in this one, and if you specify -v it will tell you the
version and quit. I fixed the defaults as you asked, and put in
defaults for N 72 and png, (and if they pick transparency a default of
png as well). If the command line args still don't work please let me
know. They work here. My experience is that whenever I'm sure I've
tested everything there are still many bugs, so please let me know:)
BTW, in the script I attached to the last email, you'll notice that
with transparent background you have a choice between either png or
gif--it's not forced to png. Is there a way to work this option into
your version?
Yep, fixed.
Patrick
