在市场导入海报画板uni_modules版本的即可,无需import
导入插件后直接使用可查看demo
<lime-painter />
l-painter-view、l-painter-text、l-painter-image、l-painter-qrcode四种类型组件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>
type为view、text、image、qrcodeboard 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)css字段,css 的 key 值使用驼峰如:lineHeight<l-painter :board="poster"/>
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",
						borderTopRightRadius: "60rpx",
						borderBottomLeftRadius: "60rpx",
						display: "inline-block",
						margin: "0 30rpx"
					},
					views: [],
					type: "view"
				},
				{
					css: {
						background: "#ff9d00",
						height: "120rpx",
						width: "120rpx",
						borderRadius: "50%",
						display: "inline-block"
					},
					views: [],
					type: "view"
				},
			]
		}
	}
}
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views 的数组字段,用于嵌套承载节点。<l-painter>
  <l-painter-view css="background: #f0f0f0; padding-top: 100rpx;">
    <l-painter-view
      css="background: #d9d9d9; width: 33.33%; height: 100rpx; display: inline-block"
    ></l-painter-view>
    <l-painter-view
      css="background: #bfbfbf; width: 66.66%; height: 100rpx; display: inline-block"
    ></l-painter-view>
  </l-painter-view>
</l-painter>
{
	css: {},
	views: [
		{
			type: 'view',
			css: {
				background: '#f0f0f0',
				paddingTop: '100rpx'
			},
			views: [
				{
					type: 'view',
					css: {
						background: '#d9d9d9',
						width: '33.33%',
						height: '100rpx',
						display: 'inline-block'
					}
				},
				{
					type: 'view',
					css: {
						background: '#bfbfbf',
						width: '66.66%',
						height: '100rpx',
						display: 'inline-block'
					}
				}
			],
		}
	]
}
text 属性填写文本内容。\n换行符line-clamp设置行数,当文字内容超过会显示省略号。text-decoration<l-painter>
  <l-painter-view css="background: #e0e2db; padding: 30rpx; color: #222a29">
    <l-painter-text
      text="登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼"
    />
    <l-painter-text
      text="登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼"
      css="text-align:center; padding-top: 20rpx; text-decoration: line-through "
    />
    <l-painter-text
      text="登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼"
      css="text-align:right; padding-top: 20rpx"
    />
    <l-painter-text
      text="水调歌头\n明月几时有?把酒问青天。不知天上宫阙,今夕是何年。我欲乘风归去,又恐琼楼玉宇,高处不胜寒。起舞弄清影,何似在人间。"
      css="line-clamp: 3; padding-top: 20rpx; background: linear-gradient(,#ff971b 0%, #ff5000 100%); background-clip: text"
    />
  </l-painter-view>
</l-painter>
// 基础用法
{
	type: 'text',
	text: '登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼',
},
{
	type: 'text',
	text: '登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼',
	css: {
		// 设置居中对齐
		textAlign: 'center',
		// 设置中划线
		textDecoration: 'line-through'
	}
},
{
	type: 'text',
	text: '登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼',
	css: {
		// 设置右对齐
		textAlign: 'right',
	}
},
{
	type: 'text',
	text: '登鹳雀楼\n白日依山尽,黄河入海流\n欲穷千里目,更上一层楼',
	css: {
		// 设置行数,超出显示省略号
		lineClamp: 3,
		// 渐变文字
		background: 'linear-gradient(,#ff971b 0%, #1989fa 100%)',
		backgroundClip: 'text'
	}
}
src 属性填写图片路径。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。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。<l-painter>
  <!-- 基础用法 -->
  <l-painter-image
    src="https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg"
    css="width: 200rpx; height: 200rpx"
  />

    css="width: 200rpx; height: 200rpx; object-fit: contain; background: #eee"

    css="width: 200rpx; height: 200rpx; object-fit: contain; object-position: 50% 50%; background: #eee"
  />
</l-painter>
// 基础用法
{
	type: 'image',
	src: 'https://m.360buyimg.com/babel/jfs/t1/196317/32/13733/288158/60f4ea39E6fb378ed/d69205b1a8ed3c97.jpg',

	css: {
		width: '200rpx',
		height: '200rpx',
		objectFit: 'contain',
		objectPosition: '50% 50%'
	}
}
text属性填写需要生成二维码的文本。css 里的 color 可设置生成码点的颜色。css 里的 background可设置背景色。css里的 width、height设置尺寸。<l-painter>
  <l-painter-qrcode
    text="limeui.qcoon.cn"
    css="width: 200rpx; height: 200rpx"
  />
</l-painter>
{
	type: 'qrcode',
	text: 'limeui.qcoon.cn',
	css: {
		width: '200rpx',
		height: '200rpx',
	}
}
parser这个包,如果你不使用是不会进入主包<l-painter ref="painter"/>
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.$refs.painter.render(json)
isCanvasToTempFilePath自动生成图片并在 @success 事件里接收海报临时路径<l-painter ref="painter">...code</l-painter>
this.$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');
		}
	});
  },
});
render函数 传递JSON即可<l-painter ref="painter" />
// 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');
		}
	});
  },
});
1、设置来源
*
2、允许Methods
GET
3、允许Headers
access-control-allow-origin:*
4、最后如果还是不行,可试下给插件设置useCORS
<l-painter useCORS>
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!

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'
painter.js支持在原生小程序中使用source里传入 JSONrender绘制海报<canvas type="2d" id="painter" style="width: 100%"></canvas>
import { Painter } from "./painter";
