Class Quality

  • public class Quality
extends Object
    Provides a structure for setting the rendering quality, i.e., the tradeoff between computation speed, and graphic quality. Following mode have an impact on the way the View makes its GL2 initialization. The Quality may also activate an AbstractOrderingStrategy algorithm that enables clean alpha results.
    • Fastest: No transparency, no color shading, just handle depth buffer.
    • Intermediate: include Fastest mode abilities, Color shading, mainly usefull to have interpolated colors on polygons.
    • Advanced: include Intermediate mode abilities, Transparency (GL2 alpha blending + polygon ordering in scene graph)
    • Nicest: include Advanced mode abilities, Anti aliasing on wires
    Toggling rendering model: one may either choose to have a repaint-on-demand or repaint-continuously model. Setting isAnimated(false) will desactivate the IAnimator updating the choosen ICanvas implementation. setAutoSwapBuffer(false) will configure the ICanvas.

        Initialize a Quality configuration for a View.

    • Method Detail

      • Nicest

        public static final Quality Nicest()
        Enables alpha, color interpolation and antialiasing on lines, points, and polygons.

      • Advanced

        public static final Quality Advanced()
        Enables alpha and color interpolation. Set HiDPI on by default

      • Intermediate

        public static final Quality Intermediate()
        Enables color interpolation. Keep HiDPI off by default

      • Fastest

        public static final Quality Fastest()
        Minimal quality to allow fastest rendering (no alpha, interpolation or antialiasing).

      • isPreserveViewportSize

        public boolean isPreserveViewportSize()
        Used by a Canvas to setup pixel ratio. This might be used to avoid mouse pointer errors on Retina display as most canvas implementation will perform : if(quality.isPreserveViewportSize()) setPixelScale(new float[] { ScalableSurface.IDENTITY_PIXELSCALE, ScalableSurface.IDENTITY_PIXELSCALE });

      • setHiDPIEnabled

        public Quality setHiDPIEnabled​(boolean hidpi)
        If true, states that the chart should make use of HiDPI or Retina capabilities to draw more good looking charts due to higher number of physical pixels. A convenient shortcut to setPreserveViewportSize(!hidpi)
