rotate

public void rotate(int degree)

Rotates the image by changing TIFF.TAG_ORIENTATION.

NOTICE: TIFF.TAG_ORIENTATION is an advice how the image is meant do be displayed. Other metadata, such as width and height, relate to the image as how it is stored. The ImageIO TIFF plugin does not handle orientation. Use TIFFUtilities.applyOrientation(BufferedImage, int) for applying TIFF.TAG_ORIENTATION.

Parameters:

degree - Rotation amount, supports 90�, 180� and 270�.
