### 4.4.3 Other programs

When integrating LilyPond scores into documents in other software, you have to effectively mimick how `lilypond-book` runs `lilypond`.

Here we discuss how to create ‘`PNG`’ images for use with online formats similar to HTML, and ‘`PDF`’ and ‘`EPS`’ for print-out formats similar to ‘`PDF`’.

PDF documents are usually formatted to enable printing. This means that long pieces of music must be distributed over several pages. For this mode of operation, invoke `lilypond` as

>     lilypond -dseparate-page-formats=pdf myfile.ly

This creates ‘`myfile-1.pdf`’, ‘`myfile-2.pdf`’, …, each containing a single page.

For embedding the images in a PostScript file, you can create ‘`EPS`’ files, using `-dseparate-page-formats=eps`. In this case, you may also want to specify `-dno-gs-load-fonts -dinclude-eps-fonts`, otherwise the ‘`EPS`’ files will not render if they are copied to another computer.

HTML documents are not printed, so they usually don’t have to worry about splitting music images across page breaks, and you can use a single (possibly very tall) image to represent a long score. This can be achieved with

>     lilypond -dtall-page-formats=png myfile.ly

yielding a ‘`myfile.png`’ that has all the pages of ‘`myfile.ly`’ stacked vertically.

Specifying either `-dseparate-page-formats` or `-dtall-page-formats` suppresses the standard output mode (single file with multiple pages) and the associated `--formats` option. Both options take a comma-separated list of formats and can be specified together, e.g.

>     lilypond -dseparate-page-formats=eps,pdf -dtall-page-formats=png,svg myfile.ly

To reduce the margins around the pages pass the `-dno-use-paper-size-for-page` option to crop extraneous whitespace. The following paper settings will elide page numbers and other footers that enlarge the page.

>     \paper{
>       indent=0\mm
>       oddFooterMarkup=##f
>       oddHeaderMarkup=##f
>       bookTitleMarkup = ##f
>       scoreTitleMarkup = ##f
>     }

>     … music …

The above discusses how pages are dumped into output files, but for music integrated into text, you often don’t want full pages (possibly including page numbers, margins etc.), but rather lines of music. This is achieved by including ‘`lilypond-book-preamble.ly`’ before a fragment of music. This makes a toplevel `\score` block render into lines of music rather than pages.

If you need to quote many fragments from a large score, you can also use the clip systems feature, see Extracting fragments of music.
