A gradle plugin for optimizing PNGs, effectively reducing APK size. Both extreme compression and lossless compression are available.
Tested on macOS、windows10、Ubuntu16.04LTS(amd64). If you have any questions, plz open issues.
Add the following Gradle configuration to your build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
...
classpath 'com.chenenyu:img-optimizer:latestVersion'
}
}
Then in your moudle's build.gradle:
apply plugin: 'img-optimizer'
Now you can see the tasks in task tree:
Double click to execute the task.
You can add the following options to custom the task:
optimizerOptions {
triggerSize 5
type "lossy"
suffix "_opt"
}
triggerSizeUsed for filtering pictures. Picture whose size is less than this option will be ignored. Defaults to 0.typeNow supports"lossy"and"lossless"。"lossy"means extreme compression(recommend, default, fast, effective)，"lossless"means loseless compression(slow, inefficient)。suffixThe suffix of the picture which has been optimized. If"_opt"，the optimizer will generate a new pictureorignal_opt.pngfororiginal.png. Defaults to null.
| Original png | Extreme compression(lossy) | Loseless compression(lossless) |
|---|---|---|
| 526K | 195K(reduce 63%) | 473K(reduce 10%) |

If there are multiple modules in your project, please add the optimizer in where you want to execute optimization since each module is independent. The optimizer will generate log file in the root directory of current module.
