generating pdf and png but no ps
Hi How can I generate pdf and png but no ps? Can I adjust resolution of the png? I just need thumbnails. Is there a simple way to see (e.g. from the shell or an external programming language) how many png-pages lilypond produced?

Ok, to clarify this a bit: I'm invoking lilypond from a php-application and want to reduce the number of shell commands as far as possible. I also dont want to tidy up any mess that is generated but not needed. I just want the most elegant way to generate a pdf and some thumbs to offer it on a web page. And I know 'rm' and 'imagemagick' :-) But it seems I need to write a wrapper for that. Seb. ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

So I have to make a loop to generate and 's. But for the loop I need the number of pages, I think. Any other ideas are aprreciated.

Sebastian Menge wrote: > How can I generate pdf and png but no ps? AFAIK for what you want, no; LilyPond needs the PS for PDF output. IIRC, recently there was a discussion about implementing a switch to automatically delete the intermediate PS, but currently there is none. So you'll have to call a rm yourself. (Which does not harm too much; it's not that rm generates much traffic even for a very restricted and low-powered PHP server, is it?) Wohoo. Just saw Gilles' mail; I think there's some possibility to call the scheme command from the commandline, too, but you seem to need a guile-user thingie... Not sure if this really helps, then. See the first paragraph here: http://lilypond.org/doc/v2.11/Documentation/user/lilypond-program/Command-line-options-for-lilypond#Command-line-options-for-lilypond > Can I adjust resolution of the png? I just need thumbnails. Grep for dresolution here: http://lilypond.org/doc/v2.11/Documentation/user/lilypond-program/Command-line-options-for-lilypond#Command-line-options-for-lilypond But: You may end up faster generating the PDF (which you seem to need anyway) and use convert (ImageMagick) or gs or something to get the PNG; you won't need a second engraving run then. (Is it possible to use --png and --pdf output in Lily simultaneously? Never bothered...) > Is there a simple way to see (e.g. from the shell or an external > programming language) how many png-pages lilypond produced? Well, three things come into my mind. > --png produces file-page1.png file-page2.png etc. First, quick 'n' dirty: ls -1 "file-page*.png" | wc -l (This is the digit one after ls (one entry per line), and the letter L after wc (count lines).) Make sure there's nothing else matching to the filename pattern. Otherwise you could do a bash loop and count until there's no file of the expected name... Or try something like ls -1 | grep -E 'file-page[0-9]+\.png' | wc -l But, since you generate the pdf anyway: Second, using pdfinfo (which I'm not sure where it comes from, but it seems to be standard. Maybe xpdf?): pdfinfo file.pdf | grep "Pages:" and remove the "Pages:\t" in your script. Third, same idea, and yet another advertising for the great pdftk (http://www.accesspdf.com/pdftk/): pdftk file.pdf dump_data | grep "NumberOfPages:" and remove the "NumberOfPages: " in your script.

Re: generating pdf and png but no ps
Sebastian,
Your situation is perfectly suited for the script that Patrick Horgan
and I wrote. Now, the script also crops the extra white space off, so
you might need to edit the script a bit if you don't want the margins
cropped off. Just look for the part in the loop that uses pnmcrop. It
handles multipage files just fine, and it cleans up .ps files as part of
the process. It's very easy to set the resolution and output format
(png is default, but it also supports many other formats). Your command
looks like this for a png output at 72 DPI:
lily2image -r=72 -f=png filename.ly
You can also make a transparent background if you want, and you can set
it to preview the converted files in your default image viewer with a -p
flag.
The only dependency is the netpbm package, easily obtained from most
linux repositories I would guess.
Script and manpage are attached.

.TH "lily2image" "1" "1.2" "Jonathan Kulp, Patrick Horgan" "Lilypond Helper
Tools"
.SH "NAME"
.LP
lily2image \- Convert lilypond source files into cropped musical examples in a
variety of image formats.
.SH "SYNTAX"
.LP
lily2image [\fIoption\fP] [\fIoption\fP] <\fIfilename.ly\fP>
.br
.SH "DESCRIPTION"
.LP
This program is designed to use Lilypond source files to create musical
examples suitable for insertion in documents and web pages. It requires the
\fBnetpbm\fR 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.
.SH "OPTIONS"
.LP
.TP
\fB\-r=, \-\-resolution=\fR
Set resolution to DPI specified by numeric value.
.TP
\fB\-f=, \-\-format=\fR
Set desired image format. For a full list of supported formats, see manpages
for the pnmto and ppmto tools from \fBnetpbm\fR.
.TP
\fB\-q, \-\-quiet\fR
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.
.TP
\fB\-p\fR
Preview. Display converted image in default image viewer, or in user\-specified
viewer if set with \-V.
.TP
\fB\-t, \-\-transparency\fR
Set background to transparent (without this option background is white). Only
png and gif formats support transparent background.
.TP
\fB\-a, \-\-about\fR
Output program information end exit.
.TP
\fB\-u\fR
Output usage information and exit.
.TP
\fB\-v\fR
Output version information and exit.
.TP
\fB\-V=\fR
Specify image viewer. Options are "evince", eye of gnome ("eog"), and
"gwenview" in Linux; "preview" in OSX.
.TP
.SH "EXAMPLES"
.LP
Since no options are set, this example will run the program in interactive mode:
.LP
lily2image filename.ly
.LP
You may specify options at the command line. The following example creates a
gif image with transparent background at a resolution of 300 dpi:
.LP
lily2image \-r=300 \-f=gif \-t filename.ly
.LP
The next example converts to png. Since resolution is not set, user will be
prompted to enter resolution value:
.LP
lily2image \-f=png filename.ly
.LP
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:
.LP
lily2image \-f=png \-q filename.ly
.LP
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:
.LP
lily2image \-f=gif \-r=250 \-t \-q \-p \-V=evince filename.ly
.SH "EXIT STATUS"
.LP
In quiet mode, program exits with various return codes.
.PD 0
.TP
.I 0
Conversion successful.
.TP
.I 40
Transparency not set and no default.

There is no option to get similar output directly from lily? Hmm, ok. These are enough workarounds to keep going. And you are right, pdftk is a *great* tool (and FYI it's just a wrapper to a java-library called iText by Bruno Lowagi. There are ports to other languages (e.g. c#) , but i dont know about any port to scheme :-) ) Thanks, S. ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

Re: generating pdf and png but no ps
Are you wondering what my lily2image project is about? Well, 1) me learning how to script (biggest reason of all, probably, since this started out only as something I was going to use myself and evolved into something much more complicated) 2) creating musical examples (by which I mean images of music notation to insert in a document or web page) from lilypond source that are cropped properly (lilypond with png output does full pages) 3) being able to choose from variety of image output formats at the same moment as calling lilypond rather than having to convert them later; 4) being able to specify parameters with easy-to-remember flags instead of long options I have to look up in the documentation every time. I suppose you could say it's a reinvention of the wheel, but this wheel rides more smoothly for me :) Jon Alexander Kobel wrote: Jonathan Kulp wrote: [...] Your situation is perfectly suited for the script that Patrick Horgan and I wrote.
