isAutoUpdate

Getter for property autoUpdate.

isConstrainProportions

Getter for property constrainProportions.

Returns:

mouseRangeSelected

Parameters

Returns:

mouseWheelMoved

mouse wheel events zoom or pan rapidly. With a physical wheel, I (jbf) found that I get 17ms per click, and this is managable. With a touchpad on a mac, these events come much faster, like 10ms per click, which can disorient the operator. So we limit the speed to 20ms per click, for now by dropping rapid clicks.

setAutoUpdate

Setter for property autoUpdate.
