I would never have come across these new features otherwise. As a bonus, \paper top-system-spacing=##f resolves the mysterious extra pixel included in my script's "viewBox="0 1 w h).

Can I reinstate that somehow, without the white-space? Not with this function. It puts everything on one line. The ly:one-page-breaking function should do what you want, but it’s still in development, not released yet. -Paul ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Ok, that wasn't clear, got it now, thanks
Works for one-line parts but also converts two line pieces to one line,
ignoring the \break. Can I reinstate that somehow, without the white-space?
I'd really like to be able to change the svg units to the pixel size of the
png than change my layouts, line-breaks etc.

Try this:
%
\version "2.19.36"
\paper {
page-breaking = #ly:one-line-auto-height-breaking
}
{ c1 }
%
The syntax is documented on that page in the Notation Reference that I linked
to in my previous message.

Removing white space from svg output
While trying to achieve svg output comparable to png output, I have reached
a workaround which comes close enough for my purposes. Now I have a question
at the other end of this!
I have this in my "defs.ily" file:
#(set-default-paper-size "a6" 'landscape)
\paper{
indent=0\mm
top-margin = 0\mm
right-margin = 0\mm
left-margin = 0\mm
print-page-number = ##f
oddFooterMarkup=##f
oddHeaderMarkup=##f
bookTitleMarkup = ##f
scoreTitleMarkup = ##f
}
Essentially minimises anything top and left of the "page". It may be more
than necessary.
I produce the png image (at 300dpi) and svg image, and file them in their
own folders.
>From the parent folder I run this shell script. This uses the pixel size of
the png to set the size of the svg, by changing the svg's width, height and
viewport sizes.
###start###
#!/bin/sh
# GNU bash, version 4.3.42(4)-release (x86_64-pc-msys)
# Assumes svg in svg folder and png in png folder with the same name for sizing
myfile=filenameNoSuffix
# ImageMagick identifies the size of the png image
well=$(identify -format "%w" png/$myfile.png)
hell=$(identify -format "%h" png/$myfile.png)
#Check that the variables now hold the size in pixels
echo well = $well
echo hell = $hell
# If png is 300dpi, divide sizes by 30 (if 100dpi, divide by 10)
wim=$(awk -v w=$well 'BEGIN { print w / 30 }')
him=$(awk -v h=$hell 'BEGIN { print h / 30 }')
# Again, check the result
echo wim = $wim
echo him = $him
# the 'sed' command replaces a line containing 'http://www.w3.org/2000/svg"; version="1.2" width="'$well'"
height="'$hell'" viewBox="0 1 '$wim' '$him'">
' svg/$myfile.svg
# "read" just keeps the window open to check values
read -p "Done, press ENTER"
##finish#
This might need tweaking for other shells.
My question is:
Can anyone see this becoming a scheme function which could sit in my
defs.ily file and save this ugly step?
I guess I mean an internal to Lilypond rather than external solution.
I'm not at all familiar with Scheme, but I did peek at "svg-output.scm". I
can't find the equivalent for png output.
Regards
Paul
