Constructor Detail

Printer

public Printer(Pager pager,
               java.awt.Graphics2D gr)

Method Detail

print

public void print(int pageNum,
                  int debugLevel)

Print the page with the given number to the Graphics2D output context.

get_debugLevel

public int get_debugLevel()

Specified by:

get_debugLevel in interface PrintContext

get_extension

public Extension get_extension(int pos,
                               Visible vis)

Gets PHYSICAL extensions for #getExtension(int,Visible), mulitplying the RAW extents with the currently valid Staff line distance.

Specified by:

get_extension in interface PrintContext

get_gr

public java.awt.Graphics2D get_gr()

Specified by:

get_gr in interface PrintContext

get_renderer

public Renderer get_renderer()

Specified by:

get_renderer in interface PrintContext

do_print

void do_print(Renderer.NoteSystem ns)

Print a note system controlled by the RunningPrefix objects which have been assigned a y-value by the Pager.

do_print

void do_print(Renderer.NoteSystem ns,
              Renderer.RunningPrefix p)

Print one staff of a note system controlled by its RunningPrefix. Pending beams are entered into global storage and printed afterwards.

printBarLine

protected void printBarLine(Renderer.NoteSystem ns,
                            Renderer.RunningPrefix p,
                            int pos,
                            BarLine bl,
                            Renderer.Measure measure,
                            float xpos)

Calculate top and bottom y position form staves crossed by a particular bar line.
FIXME MISSING substitute staves NOT CONTAINED in current print-out.

drawBeams

protected void drawBeams()

ASSUME that not Stems NOT in Beamgroup lie between stems IN Beamgroup (with same direction)

drawBeams

protected void drawBeams(java.util.Set<Printer.BeamPoint> beams)

ATTENTION combination of up AND down stems at the same beam (="knees") NOT YET SUPPORTED. FIXME
ATTENTION beam allocation / space requirements not yet considered in Pager! FIXME

drawBeamSegment

void drawBeamSegment(float startx,
                     float starty,
                     float slope,

Specified by:

drawExtension in interface PrintContext

xdraw

public static void xdraw(java.awt.Graphics2D gr,
                         float x0,
