command line format options

[Peter Leschev]

Hi,

                I want to run lilypond with only the PNG output format.

The following generates ps, pdf & png:

address@hidden ~]$ lilypond --png lily-303112308.ly
GNU LilyPond 2.5.24
Processing `lily-303112308.ly'
Parsing...
Interpreting music... [1]
Preprocessing graphical objects...
Calculating line breaks...
Calculating page breaks...
Layout output to `lily-303112308.ps'...
Converting to `lily-303112308.pdf'...
Converting to PNG...

While, the following only generates a ps file:

address@hidden ~]$ lilypond -f=png lily-303112308.ly
GNU LilyPond 2.5.24
Processing `lily-303112308.ly'
Parsing...
Interpreting music... [1]
Preprocessing graphical objects...
Calculating line breaks...
Calculating page breaks...
Layout output to `lily-303112308.ps'...

            How do I get lilypond to generate only a png file? (Don't want it 
to generate a pdf, generating a ps file is understandable)
    
Cheers,
Peter
