在 AS3 (Action Script 3.0) 中查找(加载)图像大小 [英] Finding (loaded) image size in AS3 (Action Script 3.0)

问题描述

我目前使用以下函数来加载图像，但是我无法找到一种方法来找到加载图像的宽度，我打算在使用相同函数放置下一个图像之前使用它.

Im currently using the following function to load an image, however i could not figure out a way to find the width of the loaded image, which i intend to use before placing the next image using the same function.

请注意，q 是一个变量(一个数字)，用于加载不同的图像.

Note that q is a a variable (a number) which is used to load differant images.

=X 我需要帮助获取加载的图像宽度...

=X i need help obtainning the loaded image width...

function LoadImage(q)
{
    var imageLoader:Loader = new Loader();
    var image:URLRequest = new URLRequest("GalleryImages/Album1/"+q+".jpg");
    imageLoader.load(image);
    addChild (imageLoader);
    imageLoader.x = 0 + CurrentXLength;
    imageLoader.y = 0;
    imageLoader.name = "image"+q;
    trace(imageLoader.x)
}

推荐答案

在实际加载之前，您无法知道位图的宽度:

You can't know the width of the bitmap until it's actually loaded:

function LoadImage(q)
{
    var imageLoader:Loader = new Loader();
    var image:URLRequest = new URLRequest("GalleryImages/Album1/"+q+".jpg");
    imageLoader.contentLoader.addEventListener(Event.COMPLETE, ImageLoaded);
    imageLoader.load(image);
    addChild (imageLoader);
    ...


private function ImageLoaded(e:Event):void
{
    var imageLoader:Loader = Loader(e.target.loader);
    var bm:Bitmap = Bitmap(imageLoader.content);
    var CurrentXLength = bm.width;
    ....
