Field Detail

renderer

final Renderer renderer

ownParams

final Parameters ownParams

firstPageNum

final int firstPageNum

yStart

java.util.Map<Renderer.RunningPrefix,java.lang.Float> yStart

lower y-coordinate, ie. first seen from the bottom. The RunningPrefix is used to REPRESENT a segment of a staff which falls into a NoteSystem.

pageNums

java.util.Map<Renderer.NoteSystem,java.lang.Integer> pageNums

Maps one or more NoteSystems to the same page number.

onPage

java.util.Map<Renderer.NoteSystem,java.lang.Integer> onPage

Maps each NoteSystem to the vertical number on its page, starting with "0", i.e. use normal List/Array addressing, ie. zero-based.

allStaffs

java.util.List<Staff> allStaffs

Contains only those which pass through the Staff Filter of this Pager.

heights

java.util.Map<Renderer.NoteSystem,java.lang.Float> heights

The overall height of each NoteSystem, counting filtered staves only.

Constructor Detail

Pager

public Pager(Renderer renderer,
             Parameters ownParams,
             int firstPageNum)

Argument "renderer" contains ALL data, including score, msg, parameters, etc. But Pager takes all parameters from the own argument ownParams (e.g. page height), so that the same Renderer result can be reused for pocket score, large score, voices, vocal scores etc.)
(voices are not optimal, because horizontal spacing does not comprehend multi measure rests.)
Coordinates refer to a piece of paper. Scale is mu-meter, orientation is the first quadrant:

      ^
      |
      |
      |
      +-------->
    (0,0) 
  

Parameters:

firstPageNum - "nominal number" of the very first physical page. All subsequent pages follow with ascending numbers, and all page filters etc. work on this "nominal" numbers.

Method Detail

execute

public void execute()

shipout

void shipout(Renderer.NoteSystem first,
             float allocated,
             Renderer.NoteSystem follower,
             int pageNum)

Parameters:

first - the next NoteSystem to be printed.

allocated - the HEIGHT of all note systems on the new page

follower - the first system NOT on this page, but on the next

pageNum - "nominal" number of this page
