B4J Library [Source code] ImageScaler

Introduction:
I don't know if there is any library exist to resize image in B4J non-UI app.
I thought such library will be useful to process images for web server in building REST API for e-commerce or e-learning web apps.
I found an example on web and chose the third method, from an old project call ImgScalr.
I done some experiments and manage to get it work in B4J using Inline Java.
Then I tried to compile the project as a library. boop! Done. It is so easy and I have my .jar and .xml files ready to use.

Supported file types:
  • JPG
  • JPEG
  • PNG
  • BMP
  • WBMP
Note: GIF is not supported

Additional Jar: imgscalr-lib-4.2.jar
