Question

How to achieve effect like on the pic below using AffineTransform or something on AffineTransform? Or any other effect/transform in Java that I can use on BufferedImage ?

Answer 1

The effect you want to achieve is called Skewing
Take a look at the Skew section @ http://www.javaxt.com/javaxt-core/javaxt.io.Image/

First of all download the javaxt api.
The Image class has a public constructor which accepts BufferedImage as an argument , see below

   javaxt.io.Image image = new javaxt.io.Image(java.awt.image.BufferedImage bufferedImage);
    int width = image.getWidth();
    int height = image.getHeight();
    image.setCorners(20, 70,              //UL
                     width-70, 0,         //UR
                     width+20, height-50, //LR
                     50, height);         //LL

setCorners is sed to skew an image by updating the corner coordinates. Coordinates are supplied in clockwise order starting from the upper left corner.
