Hi Federico, Étienne!
This is perfect!
I suggest this description:
Compress all the music in a single page output file. Margins, page numbers and
tagline are removed from the output.
It's not perfect, its wrong.
An example: zzztest.ly contains one score that results in a pdf with two pages if
"lilypond zzztest" is used to compile the source. But other backends give
different results:
knut@golem:~/test> lilypond --eps --pdf -dcrop zzztest.ly
GNU LilyPond 2.21.0
Processing `zzztest.ly'
[....]
Layout output to `zzztest.eps'...
Converting to `zzztest.pdf'...
Layout output to `zzztest-1.eps'...
Layout output to `zzztest-2.eps'...
Converting to `./zzztest-1.pdf'...
Converting to `./zzztest-2.pdf'...
Layout output to `zzztest.cropped.eps'...
Converting to `zzztest.cropped.pdf'...
Converting to PNG...
Success: compilation successfully completed
You see that "all the music in a single page output file" is wrong as here also
cropped eps/pdf images of every page are produced.
I remember that it is necessary to note that a bit of white space introduced by
e.g. an empty *Markup and a minimum-distance/padding etc might remain.
This can be fixed with e.g.
\paper {
[...]
oddHeaderMarkup = ##f
evenHeaderMarkup = ##f
oddFooterMarkup = ##f
evenFooterMarkup = ##f
bookTitleMarkup = ##f
scoreTitleMarkup = ##f
}
(I know that some but not all of those settings are necessary for the described
purpose, but I don't have the time to test that now.)
Knut
