lily2image -q filename.ly
The -q flag (quiet mode) makes it default to png format at 150 DPI resolution. You can specify different formats (gif, jpeg, tiff, pcx, bmp, and many others) and resolutions (pretty much any res you want) with -f and -r flags, and you can even make it have a transparent background. It relies on the "netpbm" package of image tools, which you can get from Linux repositories, or from MacPorts if you're a Mac user. This script runs equally well on Linux or Mac OSX.
I'll attach the script and the html version of the manpage. Jon Mark Polesky wrote:
When I want .png output, I usually type something like this in the command line: lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts --png my_file.ly Is it possible to do all of this from inside the .ly file? Using the ly:set-option command, I can do most of it: #(ly:set-option 'backend 'eps) #(ly:set-option 'gs-load-fonts #f) #(ly:set-option 'include-eps-fonts #t) But I can't figure out how to set --png from within the file. Can I? Thanks, Mark_______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

# Script for making image files from lilypond source suitable for use as #
# musical examples to insert in a document or web page. #
# Creator - Jonathan Kulp #
# Scripting Guru - Patrick Horgan #
#******************************************************************************#
# Change log
#
# 1.2 Added loop to image conversion to accommodate lilypond files that
# have more than one page. It loops until it has converted each of
the
# png files output by Lilypond.
# 1.1.1.12 Added final exit 0 status at end of file; updated manpage
# 1.1.1.11 Added jpg=jpeg, tif=tiff when values set at command line; added
# echoes of netpbm activity and echoes at end of process.
# 1.1.1.10 -V implies -p ph
# 1.1.1.9 Added range check to getnumval ph
# 1.1.1.8 -p flag is now necessary for preview--image is not opened in
# viewer by default. jk
# Quiet mode is really quiet as long as sufficient parameters are
# set at command line for process to succeed. jk
# 1.1.1.7 Added -p flag: allows forced preview even in quiet mode. jk
# Made quiet mode more quiet. jk
# 1.1.1.6 Changed the call to Lilypond on OSX by defining $PATH
# early in the script. Changed Patrick's "Johnny Come Lately" to
# "Major Contributor" :) and added a few echoes when formats,
# resolutions, and so forth are set. We could remove these if you
# they're too much. jk
# 1.1.1.5 Added -w option to specify white background and avoid prompt for
# transparency jk
# 1.1.1.4 Added lines to clean up png file if desired format is not png. jk
# 1.1.1.3 Changed list of Darwin viewers--Darwin doesn't have eog and evince
# Added quiet mode "-q" (I think it works!) jk
# 1.1.1.2 Fixed handling of dirs and files with spaces ph
# 1.1.1.1 Added search for default list of viewers ph
# 1.1.1 Added -a, -V and much comments changed default viewer to xdg-open ph
# 1.1 Added checking of return codes so we could
# abort if something failed. ph
# 1.0 Initial beta release jk

NAME
lily2image - Convert lilypond source files into cropped musical examples in a variety of image formats.
SYNTAX
lily2image [option] [option] <filename.ly>
DESCRIPTION
This program is designed to use Lilypond source files to create musical examples suitable for insertion in documents and web pages. It requires the netpbm package of image-manipulation tools and supports a large variety of image formats. Without options, it gathers user preferences interactively to set the following parameters: resolution, background transparency, and desired output format.
OPTIONS
- -r=<res>, --resolution=<res>
- Set resolution to DPI specified by numeric value.
- -f=<frmt>, --format=<frmt>
- Set desired image format. For a full list of supported formats, see manpages for the pnmto<format> and ppmto<format> tools from netpbm.
- -q, --quiet
- All echo messages are suppressed and terminal is silent throughout conversion process. If any parameters are not set at command line, program assumes defaults (-f=png, -r=150). If any errors occur, check return status for error codes.
- -p
- Preview. Display converted image in default image viewer, or in user-specified viewer if set with -V.
- -t, --transparency
- Set background to transparent (without this option background is white). Only png and gif formats support transparent background.
- -a, --about
- Output program information end exit.
- -u
- Output usage information and exit.
- -v
- Output version information and exit.
- -V=<viewer>
- Specify image viewer. Options are "evince", eye of gnome ("eog"), and "gwenview" in Linux; "preview" in OSX.
EXAMPLES
Since no options are set, this example will run the program in interactive mode:
lily2image filename.ly
You may specify options at the command line. The following example creates a gif image with transparent background at a resolution of 300 dpi:
lily2image -r=300 -f=gif -t filename.ly
The next example converts to png. Since resolution is not set, user will be prompted to enter resolution value:
lily2image -f=png filename.ly
In this example, the resolution is still not set, but user will NOT be prompted to enter resolution value because quiet mode is specified. Resolution will be the default 150 DPI:
lily2image -f=png -q filename.ly
The last example will produce a gif image at 250 DPI with transparent background. It will run in quiet mode (suppressing all echo messages) but will display image in Evince viewer when finished since the -p option is set and Evince is selected:
lily2image -f=gif -r=250 -t -q -p -V=evince filename.ly
EXIT STATUS
In quiet mode, program exits with various return codes.
- 0
- Conversion successful.
- 40
- Transparency not set and no default.
- 41
- Format not set and no default.
- 42
- Resolution not set and no default.
- 43
- Netpbm utilities not installed.
- 44
- Unable to find conversion program for desired output.
- 45
- Resolution from command line not positive numeric.
- 46
-
Format from command line invalid
