This looks really great but it failed when I tried to run it. I must
have messed it up when copying it over to my editor. Would you mind
attaching a working copy as a file instead of copying into the email?
Also, I think we crossed paths in our most recent posts about this. I
sent a revised version that allowed for a choice between gif and png on
transparent images and also fixed a problem I had introduced related to
tiff format. I'll attach most recent script.
I really like the flexibility your modifications introduce, being able
to bypass all the prompts. I like the prompts for myself because I have
a hard time remembering flag arguments sometimes, but even I can
probably remember these. Besides that I can use your modifications to
learn some tricks about scripting--clearly you actually *know* how to
script! I'm a total newb but am having fun learning. :)

Here's a modified version of Jonathan's unix/linux script that supports
arguments which are:
-t or --transparency : output format forced to png and you get
transparency
-r=N or --resolution==N : (example -r=72) set resolution
-f=FORMAT or --format=FORMAT : (example -f=jpeg) set output format
So, if the script is named lilytoimage, you could do:
lilytoimage -r=72 -t lilydir/myfile.ly
or
lilytoimage -r=111 -f=tiff lilydir/myfile.ly
If you don't specify any of those arguments then it works just like it
did before, except it will also ask about transparency. I don't have a
Mac to test on, so I didn't mess with the Mac version. Let me know if
there's any bugs;)
