Raw Image

The Raw Image control displays a non-interactive image to the user. You can use this for purposes such as decorations or icons, and you can change the image from a script to reflect changes in other controls. The control is similar to the Image control, but offers more options for animating the image and accurately filling the control rectangle. However, the Image control requires its Texture to be a SpriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development.

See in Glossary, while the Raw Image can accept any Texture.

Properties

Details

Since the Raw Image does not require a sprite texture, you can use it to display any texture available to the Unity player. For example, you might show an image downloaded from a URL using the WWW class or a texture from an object in a game.

The UV Rectangle properties allow you to display a small section of a larger image. The X and Y coordinates specify which part of the image is aligned with the bottom left corner of the control. For example, an X coordinate of 0.25 will cut off the leftmost quarter of the image. The W and H (ie, width and height) properties indicate the width and height of the section of image that will be scaled to fit the control rectangle. For example, a width and height of 0.5 will scale a quarter of the image area up to the control rectangle. By changing these properties, you can zoom and scale the image as desired (see also the Scrollbar control).
