给大家举荐一款性能极其弱小的图片编辑插件 tui.image-editor
疾速体验
- 首选在你的前端我的项目中装置:
npm i tui-image-editor
// or
yarn add tui-image-editor
- 当初你就去新建一个
.vue
文件,复制进去上面这段代码:
<template>
<div id="tui-image-editor"></div>
</template>
<script>
import "tui-image-editor/dist/tui-image-editor.css";
import "tui-color-picker/dist/tui-color-picker.css";
const ImageEditor = require("tui-image-editor");
export default {data() {
return {instance: null,}
},
mounted() {
this.instance = new ImageEditor(document.querySelector("#tui-image-editor"),
{
includeUI: {
loadImage: {
path: "https://uploadbeta.com/api/pictures/random/",
name: "image"
},
initMenu: "draw",
menuBarPosition: "bottom"
},
}
);
}
}
</script>
默认成果:
国际化:
工具中的形容默认都是英文的咱们先把这部分汉化一下:
// 将原有的代码改为这样

const ImageEditor = require("tui-image-editor");
const locale_zh = {

},

}
);
}
}
</script>
汉化后
这时候你会发现你可能不须要右上角的 Load
和Download
和左上角这个默认的 logo
,咱们能够通过自定义主题将这部分改掉:
批改下面的代码为:
<template>
<div id="tui-image-editor"></div>
</template>
<script>
import "tui-image-editor/dist/tui-image-editor.css";
import "tui-color-picker/dist/tui-color-picker.css";

}
);
}
}
</script>
自定义款式成果
咱们将下面的默认图片,Load
和 Download
按钮去掉了,然而会发现下面存在了一条红色的,这就节约了咱们编辑图片的空间,咱们持续优化:
须要咱们对款式进行批改
// ...
document.getElementsByClassName("tui-image-editor-main")[0].style.top = 0;
下一步咱们要拿到编辑后的图片了:
这个插件提供了一个 toDataURL
的办法, 能够将咱们编辑后的图片转为 base64
, 而后咱们能够通过转为form
表单上传到咱们的服务器,或者转为图片,这里提供一份上传到后盾的逻辑:
// ...
methods: {uploadImg() {const base64String = this.instance.toDataURL();
const data = window.atob(base64String.split(",")[1]);
const ia = new Uint8Array(data.length);
for (let i = 0; i < data.length; i++) {ia[i] = data.charCodeAt(i);
}
const blob = new Blob([ia], {type: "image/png"});
const fd = new FormData();
fd.append("image", blob);
// upload fd
}
}
最初,放上一段残缺的代码:
<template>
<div class="container">
<div id="tui-image-editor"></div>
<button @click="uploadImg"> 实现并上传 </button>
</div>
</template>
<script>
import "tui-image-editor/dist/tui-image-editor.css";
