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... 回答1: Found this library today: webp-imageio . Haven't tried it out yet, but it looks like it'll do encoding using ImageIO. 回答2: sprd-webp is another java JNI library based on webp-imageio . It is a wrapper around googles libwebp and not a real java implementation. 回答3: Java VP8 Decoder is a

There's one thing though that is a bit annoying (on mobile devices), which is the fact that you always see some parts of the browser and therefore never get a clean fullscreen user experience. We don't want to throw away the benefits of a platform-independant web-based HTML5 application, of course, but nevertheless we thought of offering an additional Android "app" to our customers, whose only purpose is to show our

Glide3.7 添加 Webp支持

问题:项目加载webp图片不显示 背景:后台的图片从png转为了webp,出现部分图片不能显示。 原因:项目使用的glide 3.7 不支持带透明效果的webp格式图片 对策: 1.使用最新的glide 4.7.1。由于相比 glide 3.7 API改动太大,需要修改很多文件,比较麻烦。 2.修改glide 3.7 源码:按照4.7.1的代码,增加webp支持,重新打包。 以下是修改方法: 文件:com\bumptech\glide\load\resource\bitmap\ImageHeaderParser.java 加入枚举值WEBP 和WEBPA ,gettype() 方法加入webp解析 相关字段 public enum ImageType { /** GIF type. */ GIF( true ), /** JPG type. */ JPEG( false ), /** PNG type with alpha. */ PNG_A( true ), /** PNG type without alpha. */ PNG( false ), /** WebP type with alpha. */ WEBP_A( true ), /** WebP type without alpha. */ WEBP( false ), /** Unrecognized type. */

1、webp格式 webp格式是谷歌开发的一种旨在加快图片加载速度的格式,将图片转为webp格式后,体积约为原来的2/3,这可以节省大量的服务器带宽,微信公众号文章里的图片就是这种格式的。 2、使用pillow模块将图片转为webp格式 #coding=utf-8 from PIL import Image im = Image.open('3.jpeg').convert("RGB") im.save("3.webp", "WEBP") 代码是很简单的,png,jpg格式的图片都可以转,转换后的文件,可以用谷歌浏览器打开
