The Zoomify Image Viewer supports rotation in 1-degree or 90 degree increments. In this example, the the HTML parameter zRotationVisible=1 is demonstrated. This setting displays the rotation buttons on the Toolbar and enables 1-degree rotation steps - or 'free' rotation.

See the next example for a demonstration of 90 degree rotation implemented using the zRotationVisible=2 setting, as well as initial rotation using the HTML parameter zInitialRotation.

Rotation respects pan constraints and can be used in initial view settings, hotspot/annotation settings, and tours and slideshows. When rotation is enabled, the '<' and '>' keys can also be used to rotate the image counter clockwise and clockwise.
