+#  OffscreenCanvas
+
+**OffscreenCanvas** provides an offscreen canvas for drawing.
+
+When using [Canvas](ts-components-canvas-canvas.md) or [Canvas API](ts-canvasrenderingcontext2d.md), rendering, animations, and user interactions generally occur on the main thread of an application. The computation relating to canvas animations and rendering may affect application performance. **OffscreenCanvas** allows for rendering off the screen. This means that some tasks can be run in a separate thread to reduce the load on the main thread.
+
+> **NOTE**
+>
+> The APIs of this module are supported since API version 8. Updates will be marked with a superscript to indicate their earliest API version.

+# Obscuring
+
+When needed, you can obscure content of a component.
+
+>  **NOTE**
+>
+> The APIs of this module are supported since API version 10. Updates will be marked with a superscript to indicate their earliest API version.
+
+
+## Attributes
+
+
+| Name   | Type                                    | Description                                 |
+| -----| ------------------------------------------ | ------------------------------------ |
+| obscured | Array<[ObscuredReasons](ts-appendix-enums.md#obscuredreasons10)> | How the component content is obscured.<br>Default value: **[]**<br>This API is supported in ArkTS widgets.<br>This API only works for the [\<Image>](ts-basic-components-image.md) and [\<Text>](ts-basic-components-text.md) components.<br>**NOTE**<br>To obscure an image when it is being loaded, you must set the width and height of the **\<Image>** component. |
+
+## Example
+
+```ts
+// xxx.ets
+@Entry
+@Component
+struct ObscuredExample {
+  build() {
+    Row() {
+      Column() {
+        Text('Text not set obscured attribute').fontSize(10).fontColor(Color.Black)
+        Text('This is an example for text obscured attribute.')

+          .width('600px')
+          .fontColor(Color.Black)
