__原始图像__控件向用户显示非交互式图像。此图像可用于装饰或图标之类的用途,还可以从脚本更改图像以便反映其他控件的更改。该控件类似于图像 (Image) 控件,但为动画化图像和准确填充控件矩形提供了更多选项。但是,图像控件要求其纹理为精灵,而原始图像可以接受任何纹理。
属性: | 功能: |
---|---|
Texture | 表示要显示的图像的纹理。 |
Color | 要应用于图像的颜色。 |
Material | 用于渲染图像的材质。 |
Raycast Target | 如果希望 Unity 将图像视为射线投射的目标,请启用 Raycast Target。 |
UV Rectangle | 图像在控件矩形内的偏移和大小,以标准化坐标(范围 0.0 到 1.0)表示。图像边缘将进行拉伸来填充 UV 矩形周围的空间。 |
由于原始图像不需要精灵纹理,因此可以使用这种图像来显示 Unity 播放器可用的任何纹理。例如,可使用 WWW 类显示从 URL 下载的图像,或显示来自游戏对象的纹理。
UV Rectangle 属性允许显示较大图像的一小部分。X 和 Y 坐标指定图像的哪个部分与控件的左下角对齐。例如,X 坐标为 0.25 将会截断图像的最左边四分之一。W 和 _H_(即宽度和高度)属性指示了要进行缩放来适应控件矩形的图像部分的宽度和高度。例如,宽度和高度为 0.5 将会将图像区域放大四分之一来适应控件矩形。通过更改这些属性,即可根据需要缩放图像(另请参阅滚动条 (Scrollbar) 控件)。
