图片中的柔性：如何改变的MX源时，为了避免闪烁 [英] how to avoid flickering when changing the source of an mx:Image in flex

问题描述

在我的MXML文件我有这样的声明图片：

in my mxml file I have images declared like this:

 <mx:Image x="0" y="0" source="assets/bigpicture.png" id="picture1"/>

和在一些事件中，我做的：

and at some event I do:

picture1.source =财产/ bigpicture2.png;

picture1.source = "assets/bigpicture2.png";

不过，这将导致弯曲删除该图片，当它加载它会再次显示。

However this results in flex removing the picture, and when it has loaded it will show it again.

我怎样才能让MX：图像制作，这样它会继续显示图像直到新的图像已经加载

How can I make the mx:image make so that it will continue to show the image until the new image has been loaded?

谢谢！

Why don't you just embed your assets in your application if they are always the same ?

如果您的图像必须在运行时加载： 我认为要做到这一点的唯一方法是分别从图像的加载程序，当加载器加载完成后加载的资产，将其指定为图像的来源。

If your images must be loaded at runtime: I think the only way to do it is to load the asset separately from the Image with a Loader, and when the Loader has finished loading, assign it as source of the Image.

否则，你可以淡出图像阿尔法= 0切换源之前，然后淡出回1.0。它看起来更平滑，但仍然会有，而新的加载任何图像显示。

Else, you can just fade the Image to alpha=0 before switching the source, and then fade it back to 1.0. It will look smoother, but there will still be no image displayed while the new one is loading.
