Re: 90 Rotation in one buffer only

and here is clockwise rotate:

public void rotate() {
int w = width - 1;
int h = height - 1;
int w2 = width / 2;
int h2 = height / 2;
int tmp;

for (int y = 0; y < h2; y++) {
for (int x = 0; x < w2; x++) {
tmp = getPixel(x, y);
setPixel(x, y, getPixel(y, h - x));
setPixel(y, h - x, getPixel(w - x, h - y));
setPixel(w - x, h - y, getPixel(w - y, x));
setPixel(w - y, x, tmp);
}
}
}
