Hi List,
Tonight I'd like to share with you some
tools I'm experimenting for a couple of
weeks that can ease to make drawings
with the 'path' command.
Almost everyone here uses postscript
images when a new glyph is needed. But it
may causes some issues (no svg, some
overrides are not possible e.g. color...)
So why not using 'path'?
For sure, when I first put my eyes here
(scroll down until 'samplePath'):
http://lilypond.org/doc/v2.18/Documentation/notation/graphic.fr.html
with its weird fight glove glyph it looked a
little mysterious. But after many trials and
with some self-made tools to help me finding
the right coordinates it revealed that it's a
pretty powerful toy.
And a recent conversation made me think that
maybe I could re-think and enhanced those tools
and shared them with you. So, here we go!
The idea is to use LP and your favorite editor as
a cad.
So please find herewith "graphPaper.ily" and an
unfinished example to show you how my glyphs are
constructed.
Basically, all you need is knowing how to find
coordinates on a graph, combining an original glyph
behind the graph paper and follow the lines with the
specific path commands: moveto, lineto, curveto,
closepath (note that I only use absolute
coordinates).
"graphPaper.ily" includes a graph paper ("1"
equivalent to the distance between 2 staff lines) and
ready to use tangents to help you to choose the right
Bézier coordinates.
