|

However, coders pefer using jar package instead of source java code in personal project. So I fork and edit qwong/j-webp to privide a usable jar. It is a fat jar includes dependencies and native lib file (includes windows/linux/mac both 32&64bit).
|
||||
|
||||
Update 20181119: sync from [webp project of Luciad](https://bitbucket.org/luciad/webp-imageio) 1.0.0
|
||||
|
||||
## Usage
|
||||
|
||||
Because it is not in maven repo, so you have to put the jar file `webp-imageio-core-{version}.jar` into libs folder of your project manually.
