using Lilypond, I can use transparency and resolution _separately_, but
unfortunately not together.

These two command lines work fine:

d:/resources/LilyPond/usr/bin/lilypond -dresolution=169.333 --png --pdf

d:/resources/LilyPond/usr/bin/lilypond -dpixmap-format=pngalpha --png --pdf

If I combine them to

d:/resources/LilyPond/usr/bin/lilypond -dpixmap-format=pngalpha
-dresolution=169.333 --png --pdf prc44_3.ly

or swapped like

d:/resources/LilyPond/usr/bin/lilypond -dresolution=169.333
-dpixmap-format=pngalpha --png --pdf prc44_3.ly

the transparency option is ignored.
Can't reproduce on Ubuntu.  There, both options apparently arrive.

I wonder if this another of those 'syntax' anomalies (where you have to escape or double-quote something).


Can someone else with Windows try this?

Perhaps Eluze - who reported the initial problems with Windows could try to work out if we need to double-double quote something somewhere?


Looks like a bug to me: it doesn't work on windows even if you ignore the command line and set the options in the lilypond file:

#(ly:set-option 'resolution 169)
#(ly:set-option 'pixmap-format "pngalpha")

resolution is set, tranparent not. Comment out the resolution line and all is OK.
