mui-image-crop

使用 MUI(@mui/material)时类似 antd Upload 组件 picture-card 预览样式的 image Crop。默认具有缩放、旋转、宽高比工具栏，支持自定义

主要是自用，默认预览样式部分直接使用的 antd upload 组件的 picture-card 的样式。

安装

npm i mui-image-crop

使用

如果时 es 模式直接：

import React, {useState} from 'react';
import ImageCrop from 'mui-image-crop';

const Sample = (props) => {
  const [value, setValue] = props;
  return (
    <ImageCrop
      value={value}
      onChange={setValue}
      preview
    >
  )
}

如果发现缺少默认的样式(一个 104*104)的方框，则需手动导入 css（es 模块可不需要手动导入）:

import 'mui-image-crop/dist/style.css';

自定义

本组件可接收 children，children 会作为 uploader（点击或拖拽上传）使用，无 children 时，默认为 antd Upload 组件的 picture-card 样式。也可以通过 uploaderProps 进行自定义容器样式，比如不需要预览，只需要一个按钮作为上传组件：

<ImageCrop
  preview={false}
  uploaderProps={{
    style: {
      border: 'none',
      width: 'auto',
      height: 'auto',
    },
  }}
  // showAspectToolbar={false}
  // aspect={1}
  // onFinish={onFinish}
>

可以自定义 onFinish 来进行结果提交，onFinish 为一个异步函数，参数就是 value （{name,url,size,originFile:File}），其中 name 为文件名,url 为 base64 字符串，originFile 为文件对象，如果返回 true，则对话框会自动关闭

支持的 props

ImageCrop.propTypes = {
  value: PropTypes.any,
  onChange: PropTypes.func,
  disabled: PropTypes.bool,
  error: PropTypes.bool,

  preview: PropTypes.bool, // true

  children: PropTypes.node,
  imageCropDialogProps: PropTypes.object,
  cropperContainerStyle: PropTypes.object,

  uploaderProps: PropTypes.shape(uploaderPropsTypes),

  ...imageCropPropTypes,
  ...imageCropSelfDefinePropTypes,

Example with sass/scss @import "~react-easy-crop/react-easy-crop";.
};

imageCropSelfDefinePropTypes是一些自定义的 props：

const imageCropSelfDefinePropTypes = {
  qulity: PropTypes.number,
  imageType: PropTypes.string, // 剪裁后图片类型，默认为原图片类型，如果不自持一般会自动置为 image/png

};

imageCardPropTypes为剪裁图片后的预览卡片的相关样式(如果不需要预览可以preview置为 false):

    PropTypes.string,
    PropTypes.func,
    PropTypes.array,
    PropTypes.object,
  ]),

  useFsAccessApi: PropTypes.bool, // Set to true to use the https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API  to open the file picker instead of using an `<input type="file">` click event.
