Constructor Detail

Renderer

public Renderer(Score score,
                Parameters params,
                MuLiMessageReceiver<XMLDocumentIdentifier> msg,
                Graphics2D graphics2D)

ATTENTION graphics2D needed ONLY for text measurement. Needs only be present if text measurement is required. Needs to behave identical to the final rendering context only in this concern.

Method Detail

                  int l)

calculateTextAdvance

public int calculateTextAdvance(String text,
                                int fontIndex,
                                Location<XMLDocumentIdentifier> loc,
                                int objIndex)

                          Location<XMLDocumentIdentifier> loc,
                          int objIndex)

resolveSizeFactor

public float resolveSizeFactor(int logSize,
                               Location<XMLDocumentIdentifier> loc,
                               int objIndex)

execute

public void execute()

Calculates (a) width for all measures, (b) partitinoning of measures to accoaladeds, and (c) heights of all staffs.
(Assignment of accoalades to pages is done in the subsequent step, by the Pager.)
