You can rotate an image by 90 degrees to change its orientation to landscape (horizontal) or portrait (vertical). If your camera contains sensors that tag photos taken in portrait orientation, your photos are automatically rotated to the correct orientation.
You can rotate an image in PaintShop Pro.
You can also rotate an image to any angle by specifying a degree of rotation or by rotating it interactively on the canvas. For information about rotating an image to straighten it according to reference points within the image, such as the horizon, see Straightening images.
You can also apply lossless rotation to JPEG images from the Manage tab while retaining all of the original image data.
You can also rotate an image by clicking the Rotate Right or Rotate Left button on the Standard toolbar.
If you want to change the center of rotation before you interactively rotate the image, hold down Ctrl, and drag the rotation pivot point (the circle at the center of the image) to a new position.
