>![](../../public_sys-resources/icon-note.gif) **NOTE:** >When using an SVG image, note that: >- The SVG image will not be drawn if the length or width of the **** component is infinity. >- If the image length and width are not specified in the SVG description, the SVG fills the **** 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: >1. If the **** 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. >2. If the **** component is big enough to afford the SVG image, this SVG image is displayed in the upper left corner of the component. ## Event In addition to the events in [Universal Events](js-components-common-events.md), the following events are supported.
