I'm receiving a null object in my custom IComparer implementation despite no null entries in the collection it is being applied to. My understanding is this can be caused by inconsistencies in the IComparer implementation. I cannot spot where this could be happening in the following code.

For reference the intent is that these are sorted by the 'correct' property first, then if they are the same, it sorts based on the 'tiebreakerDelta' property, which sorts closest to zero without …

我需要一种方法来根据提供的颜色计算较轻的十六进制颜色.我意识到我可以使用颜色转换,但我需要实际值才能生成渐变.

大家好 -

我正在使用锚点和控制点来使用curveTo创建一个形状.这一切都很好,但是当线不直时,我无法弄清楚如何让我的线穿过控制点的中心(蓝点).

这是我绘制形状的代码:

           // clear old line and draw new / begin fill
        var g:Graphics = graphics;
        g.clear();
        g.lineStyle(2, 0, 1);
        g.beginFill(0x0099FF,.1);

        //move to starting anchor point
        var startX:Number = anchorPoints[0].x;
        var startY:Number = anchorPoints[0].y;
        g.moveTo(startX, startY);

        // Connect the dots
        var numAnchors:Number = anchorPoints.length;
        for (var i:Number=1; i<numAnchors; i++) {

            // curve to next anchor through control
            g.curveTo(controlPoints[i].x,controlPoints[i].y, anchorPoints[i].x, anchorPoints[i].y);

        }
        // Close the loop
        g.curveTo(controlPoints[0].x,controlPoints[0].y,startX,startY);

我正在绘制的形状供参考:

如何修改我的代码,以便直接通过蓝色控制点？

提前致谢!
