embedded-ps stencil confusion
Hi.
I'd like to make my own stencils using PostScript
commands, but the documentation on this topic isn't
quite there yet, I guess. I don't understand how
the "string" passed to 'embedded-ps is supposed to
be formatted.
I'm using the ps backend, and the relevant lines in
/scm/output-ps.scm (lines 129-130) are pretty sparse:
(define (embedded-ps string)
string)
Here's my naive attempt, which is clearly wrong. No
error messages are generated, but no stencil appears.
My example here would be a square note-head, but it's
just an example. That is to say, I don't need work-
arounds or clever square note-head solutions; I just
want to understand how to make embedded-ps stencils.
Thanks!
Mark

Well, in this particular case the use of "line" was implied by "line
break". I could change this into "system break", but now we don't want
users to think we'll cause a system failure on their computer, do we?

I agree with using "system" iso "line" (that's one of these things I
tell my pupils every week). But I kind of prefer "line break" over
"system break".

We've already had that argument one year ago. Back then, I went to
http://en.wikipedia.org/wiki/Word_processor and found that LilyPond
hardly lacks anything you can expect from a non-WYSIWYG word
processor. (Besides, I definitely regard this as a killer-feature.)
> Also, what do you mean by "using a specific syntax"? (same

\markuplines syntax. The next sentence precisely explains what I mean:
"This syntax is described in Multi-page markup. "
And if you're wondering why the link looks buried at the end of the
paragraph, that is because of some stupid policy rule (don't know who
the hell invented it) that requires to put references at the end of
paragraphs :-)

Do you mean an @example? The same @example you explicitly forbid? :-)
I was tempted to have a markuplines @lilypond block here, but I
couldn't figure out how to print a multi-page snippet image.
Besides, once again, clicking on "Multi-page markup" is obvious enough
to know more about it.

Nope. {} does not need to be escaped but to be enclosed in double

As i have to compile 150 or more files at the same time, this is important for me.

It's up to the operating system kernel to spread the load on all CPUs (or CPU cores); e.g. if you run "lilypond -djob-count=2" and you have no other processor time-consuming tasks at the same time (if this can ever happen on Vista :-P) on a dual core CPU, the kernel should spread each lilypond process on one different core.

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.

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
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.

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

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.

.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.

Re: generating pdf and png but no ps
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: stem direction \longa
Strange, it works find over here, both with versions 2.10 and 2.11
\version "2.10.33"

\stemUp c,, c''
\stemDown c,, c''

However, if you use
\override NoteHead #'style = #'baroque
then the neo-mensural note head style is used for
brevis, longa and maxima note heads and in that style,
there are only downward pointing versions (the same
happens if you use the mensural note head style).
