You know you can have LilyPond transparent (alpha) PNGs directly by using
-dpixmap-format=pngalpha on the commandline, like:

lilypond -dresolution=300 -dpixmap-format=pngalpha --png file.ly

or by including these lines in your template:

#(ly:set-option 'pixmap-format "pngalpha")
#(ly:set-option 'resolution 300)
