Rotating

There are many reasons that you might want or need to rotate an image. If you have a scanned picture or a digital camera image that should be vertical but opens as a horizontally oriented picture, rotating it 90 degrees corrects the problem. This is a common occurrence when you use a scanner because it's usually quicker to scan with the picture horizontal, regardless of its normal orientation (see Figure 4.5).

Figure 4.5. Placing the short side horizontally shortens the scanning time.
