如何从目的地之外清除遗留物?
原标题:How to remove left-overs from destination-out?

举出一条路,然后用<条码>全球合作行动=“延伸-out”

function drawPath(ctx){
  ctx.beginPath();
  ctx.moveTo(0, 0);
  ctx.lineTo(120, 120);
  ctx.bezierCurveTo(30, 40, 30, 40, 40, 120);
  ctx.lineTo(0, 0);
  ctx.fill();
}

drawPath(ctx);
ctx.globalCompositeOperation = "destination-out";
drawPath(ctx);

Then there are leftovers on the anti-alised edges. This happens in both Firefox and Chrome.

难道我可以做些什么去除他们(或者说他们没有露面),如果没有,预计会发生这种情况吗?

最佳回答

须用甲型频道(a)抽取一条反索马里的六分机,然后由你去除这一具有同样不透明性的六分机(a*>)。

因此,如果a在0%至100%之间,则最终不透明的最高值为a = 50%。

因此,这些艺术品为expected

但是,如果你要把这种不相干的钢子再去n,那么最终的不透明性将是(a*>(1 - <>a>><>><<>n><>>>>>>)及其最高价值将不断下降。 因此,与<条码>stination-out相提并论的足够时间可能消除所有艺术品。 我认为8次是足够的。 Try it:
