    • Field Detail

      • OUTLINE_CIRCLE_HINT

        public static java.awt.RenderingHints.Key OUTLINE_CIRCLE_HINT
        Rendering hint concerning whether to draw outlines on filled circles. In bitmap contexts, such circles typically look ugly if outlines are not drawn. However, in some contexts (vector graphics, especially of transparent markers) it is a bad idea. If this hint is set to Boolean.TRUE outlines will be drawn, and if it is set to Boolean.FALSE, they will not. If it is not set, the default policy will be followed, which currently means they *will* be drawn (this represents the historical behaviour).
