| 3 | 安卓图片优化插件：能有效减少apk安装包大小，支持png/jpg转为webp，支持png图片有损无损压缩，支持jpg有损压缩 4 | 5 | ### 支持的os 6 | 7 | `macOS`、`windows10`上已经测试通过，linux上暂时没测试。 8 | 9 | ### 引入ImageOptimization 10 | 11 | 在Project的build.gradle文件中: 12 | 13 | ``` 14 | buildscript { 15 | repositories { 16 | jcenter() 17 | } 18 | dependencies { 19 | ... 20 | classpath 'com.wanglei.image-optimization:optimization:2.0' 21 | } 22 | } 23 | ``` 24 | 25 | 在你想要优化的module的build.gradle文件中引入插件: 如在多个module使用则每个module都要引入插件 26 | 27 | `apply plugin:'com.wanglei.image-optimization'` 28 | 29 | 同步之后会生成如下任务：双击执行任务即可 30 | 31 | ![](imageafter/tasks.jpg) 32 | 33 | ### 任务生成规则 34 | 35 | imageOptimization_module名字_variant名字 36 | 37 | ### 配置项 38 | 39 | 在module的build.gradle文件中添加配置选项，配置插件优化的策略以及参数: 40 | 41 | ``` 42 | ImageOptimization{ 43 | pluginStrategy = "compress" 44 | convertWebpQuality = 80 45 | jpegCompressQuality = 90 46 | appIconName = "ic_launcher" 47 | appIconRoundName = "ic_launcher_round" 48 | convertWebpType = "lossy" 49 | compressPngType = "lossless" 50 | pngCompressQuality = 79 51 | filter{ 52 | filterDirs = ["mipmap-hdpi","mipmap-xhdpi","mipmap-xxhdpi"] 53 | filterImageNames = ["cdc.PNG","wew.jpeg","c.png"] 54 | } 55 | } 56 | ``` 57 | ImageOptimization支持多项参数配置，灵活度高，可根据项目需要自己配置参数，可配置优先转为webp不能转换的在进行图片的压缩，同样你也可以配置只进行图片的压缩而不转为webp 58 | 59 | ### 配置项参数说明 60 | 61 | | 参数 | 是否必须 |参数配置 |参数说明 | 62 | |--|--|--|--| 63 | | pluginStrategy | 否 | 可配置"webp"或者"compress" | 插件运行策略参数：如配置为"webp"则会将图片优先转为webp格式，如果不能转换或者转换失败或转换为图片更大则进行图片的压缩，如配置为"compress"则只进行图片的压缩不会转为webp，此参数如不配置默认为"compress" | 64 | | convertWebpType | 否 | 可配置"lossy"或者"lossless" | webp转换类型参数："lossy"转为webp采用有损转换模式，"lossless"转为webp采用无损模式，此参数默认为"lossy" | 65 | | compressPngType | 否 | 可配置"lossy"或者"lossless" | png图片压缩类型参数："lossy"为压缩png采用有损压缩模式，"lossless"为压缩png采用无损压缩模式，此参数默认为"lossy" | 66 | | pngCompressQuality | 否 | 可配置范围为[0,100] | png图片压缩质量参数：默认为80，建议使用默认即可，此参数为compressPngType为"lossy"时起作用，也就是有损压缩才起作用 | 67 | | convertWebpQuality | 否 | 可配置范围为[0,100] | 图片转为webp的质量参数：默认为75，此参数为谷歌建议的参数，建议不要更改，转换webp有损模式下此参数才起作用 | 68 | | jpegCompressQuality | 否 | 可配置范围为[84,100] | jpg图片压缩质量参数：默认为84 | 69 | | appIconRoundName | 否 | 项目app圆形启动图标的名字，不包括图片扩展名 | 如圆形启动图标为：icon_round.png，这里配置为icon_round | 70 | | appIconName | 是 | 项目app启动图标的名字，不包括图片扩展名 | 如启动图标为：icon.png，这里配置为icon | 71 | | filterDirs | 否 | 不需要压缩或转换的图片目录名 | 如 filterDirs = ["mipmap-hdpi","mipmap-xhdpi"] ，mipmap-hdpi与mipmap-xhdpi目录下图片资源保持原样| 72 | | filterImageNames | 否 | 不需要压缩或转换的图片的名字 | 如 filterImageNames = ["cdc.PNG","wew.jpeg"] ，cdc.PNG与wew.jpeg图片均保持原样，这里要配置完整的图片名包括扩展名并且区分大小写| 73 | 74 | ### 图片压缩效果对比 75 | 76 | #### PNG图片 77 | | 原图 | 有损转为webp | 无损转为webp | lossy有损压缩 | lossless无损压缩 | 78 | |--|--|--|--|--| 79 | | ![](imageafter/h.png) | ![](imageafter/h_webp.webp) | ![](imageafter/h_webp_lossless.webp) | ![](imageafter/h_lossy.png) | ![](imageafter/h_lossless.png) | 80 | | 50.05k | 15.28k | 30.30k | 13.64k | 42.21k | 81 | 82 | #### jpg图片 83 | | 原图 | 有损转为webp | lossy有损压缩 | 84 | |--|--|--| 85 | | ![](imageafter/wece.jpg) | ![](imageafter/wece_webp.webp) | ![](imageafter/wece_lossy.jpg) | 86 | | 7.91k | 2.82k | 5.17k | 87 | 88 | #### 由于GitHub有时不能正常显示webp图片，上图webp图片可能无法正常显示，可到imageafter文件夹中查看对应图片 89 | 90 | ### 额外说明 91 | 92 | #### 插件运行的时候会有相应信息打印出： 93 | 94 | ![](imageafter/log.jpg) 95 | 96 | #### 安卓对webp图片的支持 97 | 98 | 安卓不同sdk版本对webp的支持有所不同，具体如下： 99 | 100 | sdk<14:不支持webp格式图片 101 | 14<= sdk <18:支持webp格式图片，但是不支持有透明通道的 webp格式图片 102 | sdk >=18:有透明通道的webp图片也支持 103 | 104 | 此外如果想以无损方式将png/jpg图片转为webp，需要的sdk版本最小为18。 105 | 106 | **ImageOptimization对以上情况都做了适配，你只需放心使用即可** 107 | 108 | #### .9.png图片的处理 109 | 110 | ImageOptimization插件对.9.png图片不做任何处理，既不转换也不压缩保持原样。 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | --------------------------------------------------------------------------------
