+# image-tools
+图像转换工具，可用于如下环境：uni-app、微信小程序、5+APP、浏览器（需允许跨域）
+
+## 使用方式
+
+### NPM
+
+```
+npm i image-tools --save
+```
+
+```js
+import { pathToBase64, base64ToPath } from 'image-tools'
+```
+
+### 直接下载
+
+```js
+// 以下路径需根据项目实际情况填写
+import { pathToBase64, base64ToPath } from '../../js/image-tools/index.js'
+```
+
+## API
+
+### pathToBase64
+
+从图像路径转换为base64，uni-app、微信小程序和5+APP使用的路径不支持网络路径，如果是网络路径需要先使用下载API下载下来。
+
+```js
+pathToBase64(path)
+  .then(base64 => {
+    console.log(base64)
+  })
+  .catch(error => {
+    console.error(error)
+  })
+```
+
+### base64ToPath
+
+将图像base64保存为文件，返回文件路径。
+
+```js
+base64ToPath(base64)
+  .then(path => {
+    console.log(path)
+  })
+  .catch(error => {
+    console.error(error)
+  })
+```
+
+## 提示
+
+可以利用promise来串行和并行的执行多个任务
+
+```js
+// 并行
+Promise.all(paths.map(path => pathToBase64(path)))
+  .then(res => {
+    console.log(res)
+    // [base64, base64...]
+  })
+  .catch(error => {
+    console.error(error)
+  })
+// 串行
+paths.reduce((promise, path) => promise.then(res => pathToBase64(path).then(base64 => (res.push(base64), res))), Promise.resolve([]))
+  .then(res => {
+    console.log(res)
+    // [base64, base64...]
+  })
+  .catch(error => {
+    console.error(error)
+  })
+```
