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 = $him # the 'sed' command replaces a line containing '<svg' with the line below # svg is sized in pixels by default so doesn't require units for width and height # Viewport also adds 1px to y value, which works for me sed -i ' /<svg/ c\ \<svg xmlns="http://www.w3.org/2000/svg" version="1.2" width="'$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.
