+
+### 事件回调参数说明
+
+#### **`init(ctx: SignContext)`**
+
+可以通过该事件回调暴露的 clear、revoke 等方法操作画布。
+
+```java
+interface SignContext {
+  // canvas 实例
+	ctx: object;
+	// 清空画布
+	clear(): void;
+	// 撤回
+	revoke(): void;
+  // 保存 png 图片，文件名 filename 配置仅支持 h5
+  saveImage(filename: string): Promise<object>;
+  // 返回图片临时文件路径，config 参数同 uni.canvasToTempFilePath方法，内部只是做了 Promise 化处理而已
+  canvasToTempFilePath(config: object): Promise<object>;
+  // 设置画布背景色
+  setBackgroundColor(color: string): void;
+  setLineWidth(value: number): void;
+  setLineColor(value: string): void;
+  // 获取坐标信息数组
+  getLineData(): Array<object>;
+}
+```
+
+示例：
+
+```html
+<template>
+	<v-sign @init="onSignInit"></v-sign>
+	<button @click="clear">清空<button>
+	<button @click="revoke">撤回<button>
+    <button @click="saveTempFilePath">保存临时图片路径<button>
+    <button @click="saveImage">保存图片<button>
+</template>
+<script>
+  export default {
+    methods: {
+      onSignInit(signCtx) {
+          this.signCtx = signCtx
+      },
+      // 清空
+      clear() {
+          this.signCtx.clear()
+      },
+      // 撤回
+      revoke() {
+          this.signCtx.revoke()
+      },
+      // 保存为临时图片路径，h5返回 base64
+      saveTempFilePath() {
+          this.signCtx.canvasToTempFilePath()
+      },
+      // 保存 png 图片
+      saveImage() {
+          this.signCtx.saveImage()
+      }
+    }
+  }
+</script>
+```
+
+# 子组件
+
+子组件需要包裹在 `v-sign` 组件内使用！！！
+
+## 按钮控件（v-sign-action）
+
+### 示例
+
+```html
+<template>
+  <v-sign>
+    <v-sign-action @save="save" @clear="clear" @prev="revoke"></v-sign-action>
+  </v-sign>
