var texture : Texture2D

Description描述

Returns a Texture2D generated from the downloaded data (Read Only).

从下载的数据返回一个Texture2D（只读）。

The data must be an image in JPG or PNG format. If the data is not a valid image, the generated texture will be a small image of a question mark. It is recommended to use power-of-two size for each dimension of the image; arbitrary sizes will also work but can load slightly slower and take up a bit more memory. Each invocation of texture property allocates a new Texture2D. If you continously download textures you must use LoadImageIntoTexture or Destroy the previously created texture.

数据必须是JPG或者PNG格式格式的图片。如果数据不是有效的图像，产生的纹理将是一个带问号的纹理。建议使用2的幂次大小的图片；任意大小的也可以工作但是加载的比较慢并会占用较多的内存。每个纹理属性的调用都会分配一个新的Texture2D。如果你连续的下载纹理，必须使用LoadImageInfoTexture或销毁前面创建的纹理。

For PNG files, gamma correction is applied to the texture if PNG file contains gamma information. Display gamma for correction is assumed to be 2.0. If file does not contain gamma information, no color correction will be performed.

对于PNG文件，如果包含伽马信息，伽玛校正将被应用到该纹理，显示的伽玛校正假定为2.0，如果文件没有包含伽马信息，将不会执行任何颜色校正。

JPG files are loaded into RGB24 format, PNG files are loaded into ARGB32 format. If you want to DXT-compress the downloaded image, use LoadImageIntoTexture instead.

JPG文件被加载为RGB24格式，PNG文件被加载为ARGB32格式，如果你想DXT压缩下载的图像，使用LoadImageIntoTexture替代。

If the object has not finished downloading the data a dummy image will be returned. Use isDone or yield to see if the data is available.

如果物体还没有完成数据的下载，它将返回一个虚拟图片，使用isDone或yield来查看数据是否可以用。
