equals

Check if elements represent same instance @param el Other Element or element ghost

getCanvas

Get the canvas this element is placed on

getCenter

Get transformation center

getColorFill

getParent

getTranslation

Get translation set with #setTranslation

getType

getVisible

hide

new

Constructor @param ghost Element ghost as retrieved from core methods

setCenter

Set transformation center (currently only used for rotation)
