+
+## 安装
+在市场导入**[海报画板](https://ext.dcloud.net.cn/plugin?id=2389)uni_modules**版本的即可，无需`import`
+
+## 代码演示
+
+### 插件demo
+- lime-painter 为 demo
+- 位于 uni_modules/lime-painter/components/lime-painter
+- 导入插件后直接使用可查看demo
+```vue
+<lime-painter />
+```
+
+
+### 基本用法
+
+- 插件提供 JSON 及 Template 的方式绘制海报
+- 参考 css 块状流布局模拟 css schema。
+- 另外flex布局还不是成完善，请谨慎使用，普通的流布局我觉得已经够用了。
+
+#### 方式一 Template
+
+- 提供`l-painter-view`、`l-painter-text`、`l-painter-image`、`l-painter-qrcode`四种类型组件
+- 通过 `css` 属性绘制样式，与 style 使用方式保持一致。
+```html
+<l-painter>
+	//如果使用Template出现顺序错乱，可使用`template` 等所有变量完成再显示
+	<template v-if="show">
+		<l-painter-view
+			css="background: #07c160; height: 120rpx; width: 120rpx; display: inline-block"
+		></l-painter-view>
+		<l-painter-view
+			css="background: #1989fa; height: 120rpx; width: 120rpx; border-top-right-radius: 60rpx; border-bottom-left-radius: 60rpx; display: inline-block; margin: 0 30rpx;"
+		></l-painter-view>
+		<l-painter-view
+			css="background: #ff9d00; height: 120rpx; width: 120rpx; border-radius: 50%; display: inline-block"
+		></l-painter-view>
+	<template>
+</l-painter>
+```
+
+#### 方式二 JSON
+
+- 在 json 里四种类型组件的`type`为`view`、`text`、`image`、`qrcode`
+- 通过 `board` 设置海报所需的 JSON 数据进行绘制或`ref`获取组件实例调用组件内的`render(json)`
+- 所有类型的 schema 都具有`css`字段，css 的 key 值使用**驼峰**如：`lineHeight`
+
+```html
+<l-painter :board="poster"/>
+```
+
+```js
+data() {
+	return {
+		poster: {
+			css: {
+				// 根节点若无尺寸，自动获取父级节点
+				width: '750rpx'
+			},
+			views: [
+				{
+					css: {
+						background: "#07c160",
+						height: "120rpx",
+						width: "120rpx",
+						display: "inline-block"
+					},
+					type: "view"
+				},
+				{
+					css: {
+						background: "#1989fa",
+						height: "120rpx",
+						width: "120rpx",

+
+### View 容器
+
+- 类似于 `div` 可以嵌套承载更多的 view、text、image，qrcode 共同构建一颗完整的节点树
+- 在 JSON 里具有 `views` 的数组字段，用于嵌套承载节点。
+

+			],
+
+		}
+	]
+}
+```
+
+### Text 文本
+
+- 通过 `text` 属性填写文本内容。
+- 支持`\n`换行符
+- 支持省略号，使用 css 的`line-clamp`设置行数，当文字内容超过会显示省略号。
+- 支持`text-decoration`
+
+#### 方式一 Template
+
+```html
+<l-painter>
+  <l-painter-view css="background: #e0e2db; padding: 30rpx; color: #222a29">

+		backgroundClip: 'text'
+	}
+}
+```
+
+### Image 图片
+
+- 通过 `src` 属性填写图片路径。
+- 图片路径支持：网络图片，本地 static 里的图片路径，缓存路径，**字节的static目录是写相对路径**
+- 通过 `css` 的 `object-fit`属性可以设置图片的填充方式，可选值见下方 CSS 表格。
+- 通过 `css` 的 `object-position`配合 `object-fit` 可以设置图片的对齐方式，类似于`background-position`，详情见下方 CSS 表格。
+- 使用网络图片时：小程序需要去公众平台配置 [downloadFile](https://mp.weixin.qq.com/) 域名
+- 使用网络图片时：**H5 和 Nvue 需要决跨域问题**

+
+### Qrcode 二维码
+
+- 通过`text`属性填写需要生成二维码的文本。
+- 通过 `css` 里的 `color` 可设置生成码点的颜色。
+- 通过 `css` 里的 `background`可设置背景色。
+- 通过 `css `里的 `width`、`height`设置尺寸。
+
+#### 方式一 Template
+
+```html
+<l-painter>
+  <l-painter-qrcode
+    text="limeui.qcoon.cn"
+    css="width: 200rpx; height: 200rpx"
+  />
+</l-painter>
+```
+
+#### 方式二 JSON
+

+{
+	type: 'qrcode',
+	text: 'limeui.qcoon.cn',
+	css: {
+		width: '200rpx',
+		height: '200rpx',
+	}
+}
+```
+
+### 富文本
+- 这是一个有限支持的测试能力，只能通过JSON方式，不要抱太大希望!
+- 首先需要把富文本转成JSON,这需要引入`parser`这个包，如果你不使用是不会进入主包
+
+```html
+<l-painter ref="painter"/>
+```
+```js
+import parseHtml from '@/uni_modules/lime-painter/parser'
+const json = parseHtml(`<p><span>测试测试</span><img src="/static/logo.png"/></p>`)
+this.$refs.painter.render(json)
+```
+
+### 生成图片
+
+- 方式1、通过设置`isCanvasToTempFilePath`自动生成图片并在 `@success` 事件里接收海报临时路径
+- 方式2、通过调用内部方法生成图片：
+
+```html
+<l-painter ref="painter">...code</l-painter>
+```
+
+```js
+this.$refs.painter.canvasToTempFilePathSync({
+  fileType: "jpg",
+  // 如果返回的是base64是无法使用 saveImageToPhotosAlbum，需要设置 pathType为url
+  pathType: 'url',
+  quality: 1,
+  success: (res) => {
+    console.log(res.tempFilePath);
+	// 非H5 保存到相册
+	// H5 提示用户长按图另存
+	uni.saveImageToPhotosAlbum({
+		filePath: res.tempFilePath,
+		success: function () {
+			console.log('save success');
+		}
+	});
+  },
+});
+```
+
+### 主动调用方式
+
+- 通过获取组件实例内部的`render`函数 传递`JSON`即可
+
+```html
+<l-painter ref="painter" />
+```
+
+```js
+// 渲染
+this.$refs.painter.render(jsonSchema);
+// 生成图片
+this.$refs.painter.canvasToTempFilePathSync({
+  fileType: "jpg",
+  // 如果返回的是base64是无法使用 saveImageToPhotosAlbum，需要设置 pathType为url
+  pathType: 'url',
+  quality: 1,
+  success: (res) => {
+    console.log(res.tempFilePath);
+	// 非H5 保存到相册
+	uni.saveImageToPhotosAlbum({
+		filePath: res.tempFilePath,
+		success: function () {
+			console.log('save success');
+		}
+	});
+  },
+});
+```
+
+
+### H5跨域
+- 一般是需要后端或管理OSS资源的大佬处理
+- 一般OSS的处理方式:
+
+1、设置来源
+```cmd
+*
+```
+
+2、允许Methods
+```html
+GET
+```
+
+3、允许Headers
+```html
+access-control-allow-origin:*
+```
+
+4、最后如果还是不行,可试下给插件设置`useCORS`
+```html
+<l-painter useCORS>
+```
+
+
+
+### 海报示例
+
+- 提供一份示例，只把插件当成生成图片的工具，非必要不要在弹窗里使用。
+- 通过设置`isCanvasToTempFilePath`主动生成图片，再由 `@success` 事件接收海报临时路径
+- 设置`hidden`隐藏画板。
+请注意，示例用到了图片，海报的渲染是包括下载图片的时间，也许在某天图片会失效或访问超级慢，请更换为你的图片再查看，另外如果你是小程序请在使用示例时把**不校验合法域名**勾上！！！！！不然不显示还以为是插件的锅，求求了大佬们！

+### 自定义字体
+- 需要平台的支持，已知微信小程序支持，其它的没试过，如果可行请告之
+
+```
+// 需要在app.vue中下载字体
+uni.loadFontFace({
+	global:true,
+	scopes: ['native'],
+	family: '自定义字体名称',
+	source: 'url("https://sungd.github.io/Pacifico.ttf")',
+  
+	success() {
+	  console.log('success')
+  }
+})
+
+
+// 然后就可以在插件的css中写font-family: '自定义字体名称'
+```
+
+
+### Nvue
+- 必须为HBX 3.4.11及以上
+
+
+### 原生小程序
+
+- 插件里的`painter.js`支持在原生小程序中使用
+- new Painter 之后在`source`里传入 JSON
+- 再调用`render`绘制海报
+- 如需生成图片，请查看微信小程序 cavnas 的[canvasToTempFilePath](https://developers.weixin.qq.com/miniprogram/dev/api/canvas/wx.canvasToTempFilePath.html)
+
+```html
+<canvas type="2d" id="painter" style="width: 100%"></canvas>

+
+### 旧版(1.6.x)更新
+
+- 由于 1.8.x 版放弃了以定位的方式，所以 1.6.x 版更新之后要每个样式都加上`position: absolute`
+- 旧版的 `image` mode 模式被放弃，使用`object-fit`
+- 旧版的 `isRenderImage` 改成 `is-canvas-to-temp-file-path`
+- 旧版的 `maxLines` 改成 `line-clamp`

+## 常见问题
+
+- 1、H5 端使用网络图片需要解决跨域问题。
+- 2、小程序使用网络图片需要去公众平台增加下载白名单！二级域名也需要配！
+- 3、H5 端生成图片是 base64，有时显示只有一半可以使用原生标签`<IMG/>`
+- 4、发生保存图片倾斜变形或提示 native buffer exceed size limit 时，使用 pixel-ratio="2"参数，降分辨率。
+- 5、h5 保存图片不需要调接口，提示用户长按图片保存。
+- 6、画板不能隐藏，包括`v-if`，`v-show`、`display:none`、`opacity:0`，另外也不要把画板放在弹窗里。如果需要隐藏画板请设置 `custom-style="position: fixed; left: 200%"`
+- 7、微信小程序真机调试请使用 **真机调试2.0**，不支持1.0。
+- 8、微信小程序打开调试时可以生但并闭无法生成时，这种情况一般是没有在公众号配置download域名
+- 9、HBX 3.4.5之前的版本不支持vue3
+- 10、在微信开发工具上 canvas 层级最高无法zindex，并不影响真机
+- 11、请不要导入非uni_modules插件
+- 12、关于QQ小程序 报 Propertyor method"toJSON"is not defined 请把基础库调到 1.50.3
+- 13、支付宝小程序 IDE 不支持 生成图片 请以真机调试结果为准
+- 14、返回值为字符串 `data:,` 大概是尺寸超过限制，设置 pixel-ratio="2"
+- 华为手机 APP 上无法生成图片，请使用 HBX2.9.11++（已过时，忽略这条）
+- IOS APP 请勿使用 HBX2.9.3.20201014 的版本！这个版本无法生成图片。（已过时，忽略这条）
+- 苹果微信 7.0.20 存在闪退和图片无法 onload 为微信 bug（已过时，忽略这条）
+- 微信小程序 IOS 旧接口 如父级设置圆角，子级也设会导致子级的失效，为旧接口BUG。
+- 微信小程序 安卓 旧接口 如使用图片必须加背景色，为旧接口BUG。
+- 微信小程序 安卓端 [图片可能在首次可以加载成功，再次加载会不触发任何事件](https://developers.weixin.qq.com/community/develop/doc/000ee2b8dacf4009337f51f4556800?highLine=canvas%25202d%2520createImage)，临时解决方法是给图片加个时间戳
