// xxx.ets
@Entry
@Component
struct ClipAndMaskExample {
  build() {
    Column({ space: 15 }) {
      Text('clip').fontSize(12).width('75%').fontColor('#DCDCDC')
      Row() {
        Image($r('app.media.testImg')).width('500px').height('280px')
      }
      .clip(true) // If clip is not set to true, the image is not confined by the rounded corners of the <Row> component and may extend beyond the <Row> component.
      .borderRadius(20)
      // Clip the image based on a circle with a diameter of 280 px.
      Image($r('app.media.testImg'))
        .clip(new Circle({ width: '280px', height: '280px' }))
        .width('500px').height('280px')

      Text('mask').fontSize(12).width('75%').fontColor('#DCDCDC')
      // Add a 500 px x 280 px square mask to the image.
      Image($r('app.media.testImg'))
        .mask(new Rect({ width: '500px', height: '280px' }).fill(Color.Gray))
        .width('500px').height('280px')

      // Add a 280 px x 280 px circular mask to the image.
