使用 CSS transform 实现图片旋转

在 Vue 中可以通过绑定样式实现图片旋转效果。定义一个数据属性存储旋转角度，通过点击事件修改角度值。

<template>
  <div>
    <img 
      :style="{ transform: `rotate(${rotation}deg)` }" 
      src="your-image.jpg" 
      @click="rotateImage"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      rotation: 0
    }
  },
  methods: {
    rotateImage() {
      this.rotation += 90
    }
  }
}
</script>

使用 CSS 动画实现连续旋转

添加 CSS 动画关键帧实现无限旋转效果，通过类名切换控制动画启停。

<template>
  <div>
    <img 
      :class="{ 'rotate-animation': isRotating }" 
      src="your-image.jpg" 
      @click="toggleRotation"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      isRotating: false
    }
  },
  methods: {
    toggleRotation() {
      this.isRotating = !this.isRotating
    }
  }
}
</script>

<style>
.rotate-animation {
  animation: rotation 2s infinite linear;
}

@keyframes rotation {
  from {
    transform: rotate(0deg);
  }
  to {
    transform: rotate(360deg);
  }
}
</style>

使用第三方库实现复杂旋转

安装 vue-draggable-resizable 等库可实现带拖拽功能的旋转控制。

npm install vue-draggable-resizable

<template>
  <div>
    <vue-draggable-resizable 
      :rotatable="true" 
      :w="200" 
      :h="200"
    >
      <img src="your-image.jpg" />
    </vue-draggable-resizable>
  </div>
</template>

<script>
import VueDraggableResizable from 'vue-draggable-resizable'

export default {
  components: {
    VueDraggableResizable
  }
}
</script>

实现手势旋转功能

通过监听 touch 事件计算旋转角度，适合移动端场景。

<template>
  <div 
    @touchstart="handleTouchStart" 
    @touchmove="handleTouchMove" 
    @touchend="handleTouchEnd"
  >
    <img 
      :style="{ transform: `rotate(${rotation}deg)` }" 
      src="your-image.jpg"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      rotation: 0,
      startAngle: 0,
      isRotating: false
    }
  },
  methods: {
    calculateAngle(x, y) {
      return Math.atan2(y, x) * 180 / Math.PI
    },
    handleTouchStart(e) {
      const rect = e.target.getBoundingClientRect()
      const centerX = rect.left + rect.width / 2
      const centerY = rect.top + rect.height / 2
      const touchX = e.touches[0].clientX
      const touchY = e.touches[0].clientY
      this.startAngle = this.calculateAngle(touchX - centerX, touchY - centerY) - this.rotation
      this.isRotating = true
    },
    handleTouchMove(e) {
      if (!this.isRotating) return
      const rect = e.target.getBoundingClientRect()
      const centerX = rect.left + rect.width / 2
      const centerY = rect.top + rect.height / 2
      const touchX = e.touches[0].clientX
      const touchY = e.touches[0].clientY
      const angle = this.calculateAngle(touchX - centerX, touchY - centerY)
      this.rotation = angle - this.startAngle
    },
    handleTouchEnd() {
      this.isRotating = false
    }
  }
}
</script>
