AffineTransform truncates image

Question

I have an image and I have to rotate it by 45, 90, 135, 180 degrees. What I am doing:

try {
    BufferedImage src = ImageIO.read(new File(\"src.png\"));
             


        

Answer 1

I suggest to replace

AffineTransformOp op = new AffineTransformOp(t, null);

with

AffineTransformOp op = new AffineTransformOp(t,  AffineTransformOp.TYPE_BILINEAR);

It will improve a lot the quality of the output.
