Class CanvasNewtSWT

  • All Implemented Interfaces:
    org.eclipse.swt.graphics.Drawable, ICanvas, INativeCanvas, IScreenCanvas
    public class CanvasNewtSWT
extends org.eclipse.swt.widgets.Composite
implements IScreenCanvas, INativeCanvas
    A Newt canvas wrapped in an AWT Newt is supposed to be faster than any other canvas, either for AWT or Swing. If a non AWT panel where required, follow the guidelines given in IScreenCanvas documentation.

      • setPixelScale

        public void setPixelScale​(float[] scale)
        Description copied from interface: ICanvas
        Defines pixel scale. On MacOS Retina displays, a X*Y chart uses a (X*2)*(Y*2) viewport. This makes some calculation based on viewport (such as Camera.screenToModel(IPainter, org.jzy3d.maths.Coord3d) output wrong result. When running on Retina display, those two options fixed buggy mouse selections on Retina:
        • setPixelScale(new float[]{0.5f,0.5f})
        • setPixelScale(new float[] { ScalableSurface.IDENTITY_PIXELSCALE, ScalableSurface.IDENTITY_PIXELSCALE })
