1# Image (System API) 2 3The **Image** component is usually used to display images in applications. 4 5> **NOTE** 6> 7> This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version. 8> 9> This topic describes only system APIs provided by the module. For details about its public APIs, see [Image](ts-basic-components-image.md). 10 11## Attributes 12 13### analyzerConfig<sup>11+</sup> 14 15analyzerConfig(config: ImageAnalyzerConfig) 16 17Sets the AI image analysis types, including subject recognition and character recognition. By default, all types are supported. The types cannot be dynamically modified. 18 19**System API**: This is a system API. 20 21**System capability**: SystemCapability.ArkUI.ArkUI.Full 22 23**Parameters** 24 25| Name| Type | Mandatory| Description | 26| ------ | --------------------------------------------- | ---- | ------------ | 27| config | [ImageAnalyzerConfig](ts-image-common.md#imageanalyzerconfig) | Yes | AI image analysis types.| 28 29### edgeAntialiasing<sup>11+</sup> 30 31edgeAntialiasing(value: number) 32 33Sets antialiasing for the image. This attribute applies only to SVG images. The value range is $(0.333, 1.333]$, with precision limited to 3 decimal places. 34 35This attribute can be used to optimize jagged edges in SVG images on devices with PPI lower than 200, but it may compromise the performance. Exercise caution when using this attribute. 36 37**System API**: This is a system API. 38 39**System capability**: SystemCapability.ArkUI.ArkUI.Full 40 41**Parameters** 42 43| Name| Type | Mandatory| Description | 44| ------ | ------ | ---- | ----------------------------------- | 45| value | number | Yes | Antialiasing strength of the image.<br>Default value: **0.0**.| 46 47### pointLight<sup>11+</sup> 48 49pointLight(value: PointLightStyle) 50 51Sets the point light style. 52 53**System API**: This is a system API. 54 55**System capability**: SystemCapability.ArkUI.ArkUI.Full 56 57**Parameters** 58 59| Name| Type | Mandatory| Description | 60| ------ | ------------------------------------------------------------ | ---- | ------------ | 61| value | [PointLightStyle](ts-universal-attributes-point-light-style-sys.md#pointlightstyle) | Yes | Point light style.| 62 63### enhancedImageQuality<sup>12+</sup> 64 65enhancedImageQuality(imageQuality: ResolutionQuality) 66 67Sets the image resolution for decoding the image. 68 69This attribute does not support non-decoded image types such as SVG, [PixelMap](../../apis-image-kit/arkts-apis-image-PixelMap.md), and [DrawableDescriptor](../js-apis-arkui-drawableDescriptor.md#drawabledescriptor). 70 71**System API**: This is a system API. 72 73**System capability**: SystemCapability.ArkUI.ArkUI.Full 74 75**Parameters** 76 77| Name| Type | Mandatory| Description | 78| ------ | --------------------------------------- | ---- | -------------------------------- | 79| imageQuality | [ResolutionQuality](#resolutionquality12) | Yes | Image resolution used for decoding.| 80 81## ResolutionQuality<sup>12+</sup> 82 83Enumerates the image resolutions used for decoding the image. 84 85**System API**: This is a system API. 86 87**System capability**: SystemCapability.ArkUI.ArkUI.Full 88 89| Name | Description | 90| ------ | -------------------------- | 91| Low | Low resolution, with moderate decoding time. | 92| Medium | Medium resolution, with moderate decoding time. | 93| High | High resolution, with long decoding time. | 94
