Re: Printing, publishing the music sheet...
I would like to have to manage only 1 picture per nwc file ad'hoc for printing and web-publishing.
How do you do that?
The first step would be to find a file format that supports more than one page per file and is displayable in browsers without an addon. I know of no such format. For my personal ad'hocery, I use multipage tiff files, but that won't help you with web publishing.
I would not recommend jpeg for NWC produced music.
