Attributes
Name | Type | Description |
---|---|---|
borderImage | BorderImageOption | Border image or border gradient. This API is supported in ArkTS widgets. |
BorderImageOption
This API is supported in ArkTS widgets.
Name | Type | Description |
---|---|---|
source | string | Resource | linearGradient | Source or gradient color of the border image. NOTE The border image source applies only to container components, such as <Row>, <Column>, and <Flex>. |
slice | Length | EdgeWidths | Slice width of the upper left corner, upper right corner, lower left corner, and lower right corner of the border image. Default value: 0 NOTE If this parameter is set to a negative value, the default value is used. When this parameter is set to a value of the Length type, the value applies to the four corners in a unified manner. When this parameter is set to a value of the EdgeWidths type: - Top: slice height of the upper left or upper right corner of the image. - Bottom: slice height of the lower left or lower right corner of the image. - Left: slice width of the upper left or lower left corner of the image. - Right: slice width of the upper right or lower right corner of the image. |
width | Length | EdgeWidths | Width of the border image. Default value: 0 NOTE If this parameter is set to a negative value, the default value is used. When this parameter is set to a value of the Length type, the value applies to the four corners in a unified manner. When this parameter is set to a value of the EdgeWidths type: - Top: width of the top edge of the border image. - Bottom: width of the bottom edge of the border image. - Left: width of the left edge of the border image. - Right: width of the right edge of the border image. If this parameter is set to a negative value, the value 1 is used. |
outset | Length | EdgeWidths | Amount by which the border image is extended beyond the border box. Default value: 0 NOTE If this parameter is set to a negative value, the default value is used. When this parameter is set to a value of the Length type, the value applies to the four corners in a unified manner. When this parameter is set to a value of the EdgeWidths type: - Top: amount by which the top edge of the border image is extended beyond the border box. - Bottom: amount by which the bottom edge of the border image is extended beyond the border box. - Left: amount by which the left edge of the border image is extended beyond the border box. - Right: amount by which the right edge of the border image is extended beyond the border box. |
repeat | RepeatMode | Repeat mode of the source image's slices on the border. Default value: RepeatMode.Stretch |
fill | boolean | Whether to fill the center of the border image. Default value: false |
RepeatMode
This API is supported in ArkTS widgets.
Name | Description |
---|---|
Repeat | The source image's slices are tiled. Tiles beyond the border box will be clipped. |
Stretch | The source image's slices are stretched to fill the border box. |
Round | The source image's slices are tiled to fill the border box. Tiles may be compressed when needed. |
Space | The source image's slices are tiled to fill the border box. Extra space will be distributed in between tiles. |
Example
Example 1

angle: 90,
direction: GradientDirection.Left,
colors: [[0xAEE1E1, 0.0], [0xD3E0DC, 0.3], [0xFCD1D1, 1.0]]
},
slice: { top: 10, bottom: 10, left: 10, right: 10 },
width: { top: "10px", bottom: "10px", left: "10px", right: "10px" },
