RE: Vertical spacing tweaks.

[Fairchild]

Han-Wen -

What I proposed is to implement individual line spacing control
with\breakSpace #n to force n staff spaces between lines, and
\pageBreakSpace #n to force n staff spaces at the bottom of a page.  Spacing
following normal breaks or those forced with \break or \pageBreak would be
calculated as now.

This presents a simple syntax to the user, and allows precise vertical
spacing of individual lines or of an entire page if each line is followed by
a \breakSpace or \pageBreakSpace.

I could implement the following:


- add a property

     line-break-system-details

to NonMusicalPaperColumn


- This is an alist of properties, that are applied to the system following a
line-break at that point.

It could support the following properties:

     Y-extent -- set the vertical size of the system (used as vertical 
"rods")

     Y-refpoint-extent -- set the vertical size of the refpoints (used 
as vertical "springs")

PRICE: 130 euro



In addition, I could also make an

     alignment-stretch-factor -- scale parameters used for vertical 
alignments.

This would make it possible to set the distance between staves in 
individual staves easily.

PRICE: 130 euro



With these feature in place, it would be possible to control vertical 
spacing after line breaks.  Of course, it's up to the user to force 
certain breakpoints.



If there is sufficient interest, I can also include a -ddump-breaks , 
which writes a

   line-breaks.ly

file, containing


   breakLayout = { \skip 1*4
     \break
     \skip 1*3/4
     \break
     \pageBreak
       .. etc ..
   }

so that you can use page and line break layout, by doing

   \score {
      <<  ..my Music..
          \breakLayout
      >>
   }


PRICE: 130 euro


Contact me if you want to (co-)sponsor any of these features. Prices 
include debugging, example files and limited documentation.  Payment 
costs and VAT (if applicable) are included in the prices.
