Package eu.bandm.music.applications.feldproj

Class FeldmanVisual

java.lang.Object
eu.bandm.music.applications.feldproj.FeldmanVisual
public class FeldmanVisual extends Object
Creates a sequence of pages which come close to the original graphic notation of Morton Feldman. Use only once: construct a fresh instance for a score and call render(int,int). After completion one (a) can get the images from pages or (b) let them write to ".png" files by writeToFiles(java.io.File,java.lang.String).

The dimensions are as follows 

     <---------- page width ------------------------------------>
     <---------- text width ------------------------------->
