Webpack (Encore): convert images to webp using image-webpack-loader

谁说我不能喝 提交于 2019-12-02 02:20:35
I am trying to convert my jpeg images to the webp format using the image-webpack-loader plugin in Webpack Encore. The following config successfully minifies my files but does not convert them to webp images. webpack.config.js test: /\.(gif|png|jpe?g|svg)$/i, loader: 'image-webpack-loader', options: { disable: true, //bypassOnDebug convertPathData: false, mozjpeg: { //works progressive: true, quality: '80-90' }, webp: { //doesn't convert my images to webp quality: 75, enabled: true } } How can I achieve what I want using the plugin image-webpack-loader ? Or is there another plugin I should use

本专栏专注分享大型Bat面试知识,后续会持续更新,喜欢的话麻烦点击一个关注 github面试↓专题链接 关于我 面试官: 类比于微信,如何对Apk进行极限压缩,谈下Android压缩8大步 (面试官是非常注重性能优化的,考求职者是否具备APK压缩技能) 求职者:应该从每一步压缩开始,压缩的过程本质是挤牙膏的过程,一步一步挤。将Apk压缩分为8个步骤 一.简介 随着项目的不断迭代,代码量跟资源文件不断增多。那么就会出现打包后的 APK 文件越来越大,如果突然有一天你们老板或领导叫你优化 APK 大小,你还不知道怎么优化那就有点说不过去了,这篇文章咱们就来一起分析并优化 APK 体积大小吧。 二.分析 APK 资源占用 注意: 在 GitHub 找了一个人气比较高的开源项目,需要的话自己可以点击 下载 ,自己动手尝试一番. 分析工具直接用的 AS Build/Analyze APK 从上面图中得出 assets > classes.dex > res > lib 其中资源文件占用最大。 下面我们就来看看怎么减小 APK 大小吧, 三.优化 APK 体积八大步 1. 将图片转换为 webp 格式 Webp 概念 WebP 是一种同时提供了有损压缩与无损压缩的图片文件格式,派生自视频编码格式 VP8。WebP 最初在2010年发布,目标是减少文件大小,但达到 和 JEPG

How to create a .webp image in PHP

How do you create .webp images using PHP? Modern versions of PHP (>= 5.5.0) can be compiled with WebP support but from I've seen this isn't common on many web hosts. If compiled with WebP support you can use the built-in imagewebp() function to create .webp images. What are the alternatives for creating .webp images using PHP? Libraries, APIs other methods? The options currently available are: gd (extension), imagick (extension), imagick (exec-call), gmagick (extension), gmagick (exec-call), cwebp (exec-call), gmagick (exec call) or calling a cloud service. I have created a library 'webp

ImageMagick是一款功能强大的图片处理工具包,很多互联网应用中都会涉及到图片处理工作,比如切割、缩放、水印、格式转换等。ImageMagick就是一个理想的工具包。这里主要记录一下Linux RedHat 2.6.18下的环境安装过程。 安装基础依赖: 先检查一些基本的图片支持包是否已经安装,比如jpge和png RedHat环境下: rpm -qa | grep libpng-devel rpm -qa | grep libjpeg-devel 如果没有,可以用yum或者下载源码安装: yum -y install libpng-devel libjpeg-devel 安装webp库: 先下载libwebp-0.3.0.tar.gz tar -zxvf libwebp-0.3.0.tar.gz cd libwebp-0.3.0 ./configure && make && make install cp /usr/local/lib/libwebp.so.4.0.2 /usr/lib64/ ln -s /usr/lib64/libwebp.so.4.0.2 /usr/lib64/libwebp.so.4 ln -s /usr/lib64/libwebp.so.4.0.2 /usr/lib64/libwebp.so 安装ImageMagick: tar -zxvf

WebP library for java? [closed]

落爺英雄遲暮 提交于 2019-11-30 11:19:03
Is there a library in java for creating/saving image files in the WebP format ? I couldn't find anything that does this, except for googles encoder which is an exe file, and I don't want to have to execute some .exe from my code to do this... Found this library today: webp-imageio . Haven't tried it out yet, but it looks like it'll do encoding using ImageIO. sprd-webp is another java JNI library based on webp-imageio . It is a wrapper around googles libwebp and not a real java implementation. Java VP8 Decoder is a GPL3 library currently in beta that can read webp image format. It seems there

It seems like there is no code samples for WebP in C#. Is there any? I don't need to display WebP images directly but saving & transferring as WebP would be nice. Deano Take a look at http://webp.codeplex.com/ . There is a library that allows you to easily encode into WebP format. Check out this question for more information: Convert Bitmap to WebP Image? The library allows you to save into WebP format like so: using (Image image = Image.FromFile("image.jpg")) { Bitmap bitmap = new Bitmap(image); WebPFormat.SaveToFile("image.webp", bitmap); } WebP-wrapper Wrapper for libwebp in C#.
