Line appears in image after scaling

[Markus Svensson]

Hi,

I'm having a problem with image scaling. When I use the following code to scale an image it ends up with a line either at the bottom or on the right side of the image.

    
double scale = 1;
if (scaleHeight >= scaleWidth) {
    scale = scaleWidth;
} else {
    scale = scaleHeight;
}
AffineTransform af = new AffineTransform();
af.scale(scale, scale);

AffineTransformOp operation = new AffineTransformOp(af, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
BufferedImage bufferedThumb = operation.filter(img, null);

The original image is here: http://tinyurl.com/yzv6r7h
The scaled image: http://tinyurl.com/yk6e8ga

Does anyone know why the line appears?

Thanks!
