Class CellLatticeOSX

java.lang.Object
  org.opensourcephysics.display.Grid
      org.opensourcephysics.display2d.CellLatticeOSX

All Implemented Interfaces:

Drawable, Measurable, ByteLattice

public class CellLatticeOSX
extends Grid
implements Measurable, ByteLattice

A Mac version of CellLattice that displays an array where each array element can assume one of 256 values. Early versions of Java on Mac OSX were not able to set pixels in an image raster. This class implements an alternate CellLattice that does not use an image raster. Values can be set between -128 and 127. Because byte values larger than 127 overflow to negative, values can also be set between 0 and 255. The lattice is drawn as an array of rectangles to distinguish between the two possible values.
