ImageScaler-b4j

A B4J wrapper for ImgScalr (https://github.com/rkalla/imgscalr)

Current version: 1.0

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

Usage:

Sub ResizeImages
    Private img As ImageScaler
    img.Initialize
    img.ResizeImage(File.DirApp, File.DirApp, "Sonic.jpg", 200, 200, "AUTOMATIC")
    img.ResizeImage(File.DirApp, File.DirApp, "Puss.png", 300, 300, "FIT_TO_WIDTH")
    img.ResizeImage(File.DirApp, File.DirApp, "Logo.bmp", 150, 150, "FIT_TO_HEIGHT")
End Sub
