Re: Lilypond EPS inside Adobe Illustrator

[Valentin Petzel]

Hi Rip,

the problem is that while Lilypond will embed the glyphs into the eps it will 
reference them with a simple sequence. This cannot really be interpreted as 
text (the first glyph will be referenced as "1", which is the "Start of 
Heading" character). So either this will in fact fail to extract this glyph at 
all, or it will turn it into a string containing a simple CC, which is then of 
course not displayed.

If you include enough glyphs you will get normal chars (try for example this

#(define glyph-list
    (lset-difference
     equal?
     (ly:otf-glyph-list (ly:system-font-load "emmentaler-20"))
     '(".notdef" "backslash")))

\markuplist #(map (lambda (x) (markup #:musicglyph x))
                  glyph-list)

), but these will probably simply be rendered with any font available on the 
system instead of the actual glyphs (unless AI does a thing where it tries to 
reconstruct the font from the embedded glyphs, which would defintely require 
more effort than simply importing the glyphs and replacing the font references 
with references to these glyphs, which AI does not appear to be doing in this 
case.

But then this is not really an issue of Lilypond but of how AI imports file 
with such glyphsets. Also going into AI via eps seems a bit counterintuitive 
for me. After all PS is not particularly good at storing data in a machine 
readable way, so AI will have to try to interpret what it sees. Instead, why 
not go for SVG-Output, which is a format that is intended to store data in a 
machine readable way and simply has to be parsed by AI? In fact the SVG output 
will not store these glyphs as font references, but will insert paths, getting 
rid of all dependencies to specfic font files (although I remember that with 
much earlier versions like I think 2.18 this was not the case).

Cheers,
Valentin
