Calculate spacing in lilypond

2010-07-20 Thread cab
Hello everyone,


I have been using lilypond for 2 years now in a project called "psautiers"
(psalm in french) to create database of music : you can see examples at my
website www.psautiers.org. Yet I used the scripts musicxml2ly and lilypond to
create a jpeg from a musicxml file. Now that everything works fine, I would like
to implement a way of changing colors in a few notes (for example to color the
first notes of my score, or to color the predominant note in a melody), but to
do this I have two solutions :

-reexecuting lilypond and musicxml2ly to color a few notes which is very costy
in time and in CPU because I use a system command.
-or finding how you implemented the spacing in lilypond and directly coloring
the corresponding notes in the jpeg file.

I tried to look at the source using apt-get source lilypond and I then went to
the lily directory. However I did not find what I searched for.

Is the algorithm difficult to grasp? You may provide me a better way to
underline of color a few notes.


Thanks very much

Dang Nguyen Bac

Converting ly to musicxml

2011-07-10 Thread cab
Hi,


I have been using lilypond for 3 years in my projects:
http://www.psautiers.org (this is the website on which I am currently
working on), and http://www.score-catcher.org (the sister site) in which
I convert musicxml to lilypond and then I put the score online.

The thing is that the musicxml format is not the one most people use,
so I can't put on many scores online...

However I think it would be easier to convert ly to musicxml

(in fact i want to convert like this : midi -> ly -> musicxml).
Converting from midi to ly is possible, but ly to musicxml has never
been done... So my plan is to program it myself
I think I would do it in python as musicxml2ly is also written in python.

Do you have anything to say about it ?
Will I face some problems I have not thaught of?
Have I missed anything that would really make this task easier?

If I manage to do it , will it be possible to add it in the source tree ?

And a last request , can you link my website (psautiers.org or
score-catcher.org or both) from your website?


Thanks really much for your help

Dear Mike,

Actually, I am really interested, but I am wondering why you used scheme
, is it because you are doing this recursively ?
Is it because it is easier to parse ly files with scheme (I don't know
this language yet ) ?

Thanks really much

Sorry , in fact , one guy has already done it :
http://www.phpclasses.org/browse/file/5121.html
http://dasdeck.de/staff/valentin/midi/

Yeah , i really missed the thing , really sorry

Thanks very much for your help,

Everything will go smoothly then...

In fact, the php class provided here :
staff.dasdeck.de/valentin/midi/mid2xml.php  does not convert in musicxml
I think I found a way , just by using finale ,or noteedit, or whatever

About the website, I programmed an engine to search for melodies in
scores, and then I use lilypond to display the score and to hear the music

as for the ly-> xml converter, I have been thinking of reusing
the to-xml.scm (yeah i think I just grasped how lilypond was built)

I would just remove the *->strings part, replacing them with
(define-method (display [])) like in font.scm.
But I don't know yet how I would build the xmldoc tree (once everything
is programmed),
What do you think about it ? Am i wrong doing so,(it would my first time
contributing to the open-source community).

Thanks
