By default, changing +the angle requires recalculation of the whole screen, but when **fast rotation +mode** is enabled, the angle can be changed smoothly. In this mode XaoS +calculates a larger non-rotated image and rotates it when needed, so it +increases memory requirements and slows XaoS down; hence, it should be disabled +when rotation is not being used. + +The user interface provides two rotation modes--**rotate by mouse** which +allows the angle to be changed by dragging with the first mouse button +depressed, and **continuous rotation mode**, where the image is rotated +clockwise continuously, and the arrow keys can be used to change the rotiation +speed. + +**Syntax**:(fastrotate bool) + +This function is used to enable and disable fast rotation mode. + +**Available as**: command line option, command + +Automatic rotation +------------------ + +**Syntax**:(autorotate bool) + +Use this function to enable continuous rotation.
