Image BASE64 conversion involves converting images into BASE64 encoded strings and decoding them back to images. BASE64 encoding represents binary data in ASCII format, making it suitable for embedding images in text-based formats like HTML or CSS. Converting images to BASE64 allows them to be ...
对上传图片进行压缩的需求是非常常见的,简单来说,解决方式就是将图片base64或者canvas进行压缩转化,有很多工具包可以实现这种需求 以Vue + iView 为例:用的是image-conversion (大部分UI组件的上传都有相同的钩子方法,大同小异) 1.安装依赖+组件中引入 1 npm i image-conversion <br><br>import* as imageConve...
getBase64(img, (dataURL) => { imgRes = dataURLtoFile(dataURL,img); console.log(imgRes) callback(imgRes) }); } function getBase64(url, callback) { //通过构造函数来创建的 img 实例,在赋予 src 值后就会立刻下载图片,相比 createElement() 创建 <img> 省去了 append(),也就避免了文档冗余...
首先拿到图片资源,用 FileReader 去读取,读的过程中用readAsDataURL方法把 File 转成dataURL(base64编码字符串) 读取成功触发 reader 的 load 事件,此时把dataURL赋值给创建的空new Image()的src image 开始加载,触发 image 的 onload 事件,在此处进行压缩,再将压缩完的值返回过来。
let imgObj = this.base64ImgtoFile(data) let self = this this.imgCompression(imgObj).then(res=>{ //res为imgCompression函数压缩处理后的file格式图片 //调用上传图片接口,根据接口选择图片格式类型 this.getBase64(res,(imgbase)=>{ //imgbase为压缩后的base格式图片 ...
Version 0.14.1 Cloud or Self Hosted Self Hosted (Docker) Steps to reproduce When using the Dify LLM node for visual recognition, I noticed that the returned tokens and USD consumption are incorrect. LLM image recognition converts images to base64 and sends them to GPT. An image is typically...
