请问 为什么Image组件使用rotate方法旋转后无法占满整个屏幕？谢谢大佬

@Entry
@Component
struct Index {
@State rotateAngle: RotateOptions = { centerX: ‘50%’, centerY: ‘50%’, angle: 90 }
build() {
Column() {
Image($r(“app.media.img1”))
.width($r(“app.string.per_100”))
.height($r(“app.string.per_100”))
.objectFit(ImageFit.Contain)
.rotate(this.rotateAngle)
.onClick(event => {
this.rotateAngle.angle = this.rotateAngle.angle as number + 90
})
}.width($r(“app.string.per_100”)).height($r(“app.string.per_100”))
}
}
