XUserGamerPictureSize

指定玩家图片的大小（像素）。

语法

enum class XUserGamerPictureSize  : uint32_t  
{  
    Small = 0,  
    Medium = 1,  
    Large = 2,  
    ExtraLarge = 3,  
}  

常量

常量	说明
小	小图片：64x64 像素。
中	中图片：208x208 像素。
大	大图片：424x424 像素。
特大	特大图片：1080x1080 像素。

备注

要异步检索用户的玩家图片，请调用 XUserGetGamerPictureAsync 函数。 XUserGetGamerPictureAsync 函数采用 XUserGamerPictureSize 枚举作为参数。 XUserGetGamerPictureResult 函数检索 XUserGetGamerPictureAsync 函数返回的结果。

下面的示例演示如何加载玩家图片。
