Package org.jmol.awtjs2d

Class Platform

  • All Implemented Interfaces:
    FontManager, GenericPlatform
    Direct Known Subclasses:
    Platform
    public class Platform
extends java.lang.Object
implements GenericPlatform
    JavaScript 2D canvas version requires Ajax-based URL stream processing. Jmol "display" --> HTML5 "canvas" Jmol "image" --> HTML5 "canvas" (because we need width and height) Jmol "graphics" --> HTML5 "context(2d)" (one for display, one off-screen for fonts) Jmol "font" --> JmolFont Jmol "fontMetrics" --> HTML5 "context(2d)" (Not fully implemented)
