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;)
