Rotation
can be used to rotate Gum components. Rotation is measured in degrees, where positive values rotate an object counterclockwise about its origin (X Origin and Y Origin).
An object is rotated about its origin, which by default is its top-left corner:
Objects can also be rotated visually by grabbing the rotation handle:
Holding the SHIFT key snaps angles to 15 degree increments.
The X Origin and Y Origin properties define the point of rotation for an object. The following animation shows how changing origin values can affect rotation.
