| object-fit | string | cover | No| Image scale type. For details about available values, see **object-fit**. This style is not supported for SVG images.|

**Table 1** object-fit

| Type| Description|
| -------- | -------- |
| cover | The image is scaled with its aspect ratio retained for both sides to be greater than or equal to the display boundaries and displayed in the middle.|
| contain | The image is scaled with the aspect ratio retained for the image to be completely displayed within the display boundaries and displayed in the middle.|
| fill | The image is scaled to fill the display area, and its aspect ratio is not retained.|
| none | The image is displayed in the middle with its aspect ratio and size retained.|
| scale-down | The image is displayed in the middle with its aspect ratio retained, in the size equal to or smaller than the original size.|

>  **NOTE**
>
>  When using an SVG image, note that:
>
>  - The SVG image will not be drawn if the length or width of the parent component is infinity. Therefore, you are advised to set the length and width for the **Image** component.
>
>  - If the image length and width are not specified in the SVG description, the SVG image fills the **Image** component area.
>
>  - If the image length and width are specified in the SVG description, the following rules are adopted to decide the final display effect:
>
>    - If the **Image** component is too small to afford the SVG image, the SVG image is cropped and only its upper left part is displayed in the component.
>
>    - If the **Image** component is big enough to afford the SVG image, the SVG image is displayed in the upper left corner of the component.
