				+### 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` 
			 | 
		
	
		
			
				 | 
				 | 
			
			
				+ 
			 | 
		
	
		
			
				 | 
				 |

			 | 
		
	
		
			
				 | 
				 | 
			
			
				+- 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!

				+## 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
