For instance, I'm applying filters to large bitmaps. At the moment it works on a Timer, but I'd like to wait until any processing's been completed and progress to the next iteration at that point, instead of forcing it when the next tick comes around.
例如,我正在将过滤器应用于大型位图。目前它适用于Timer,但是我想等到任何处理完成并进入下一次迭代,而不是在下一个时钟周期时强制执行。
Pretty sure this can't be done. Anyone?
很确定无法做到这一点。任何人?

BitmapFilter, the super class of all filters, doesn't extend from EventDispatcher class nor does it implement IEventDispatcher interface. So no, filters don't dispatch events.
BitmapFilter是所有过滤器的超类,不会从EventDispatcher类扩展,也不会实现IEventDispatcher接口。所以不,过滤器不会调度事件。

Filters are called synchronously so there's no event to wait for, it's done once the next line of code is executed.
过滤器是同步调用的,所以没有等待的事件,一旦执行下一行代码就完成了。

grapefrukt: well, usually, but applying a glow or blur to a massive bitmap with transparent bits can take ages. So while it's still technically synchronous, I wanted to wait till it was done before doing the next bit.
grapefrukt:通常,但是对于带有透明位的大型位图应用发光或模糊可能需要很长时间。因此,虽然它在技术上仍然是同步的,但我还是要等到它完成之后才进行下一步。
Didn't think it could be done, but thought it was worth a shot! Cheers.
没想到可以做到,但认为值得一试!干杯。
