Squeak Documentation - Class: ImageMorph

	accessing	top
	color: Set the receiver's color. Directly set the color if appropriate, else go by way of fillStyle

	form For compatability with SketchMorph.

	image

	image:

	isOpaque Return true if the receiver is marked as being completely opaque

	isOpaque: Mark the receiver as being completely opaque or not

	setNewImageFrom: Change the receiver's image to be one derived from the supplied form. If nil is supplied, clobber any existing image in the receiver, and in its place put a default graphic, either the one known to the receiver as its default value, else a squeaky mouse

card & stack top

basicType

Answer a symbol representing the inherent type I hold

couldHoldSeparateDataForEachInstance

Answer whether the receiver can potentially hold separate data for each instance

currentDataValue

Answer the current data value of the receiver, to be stored in each card instance if appropriate

variableDocks

Answer a list of VariableDock objects for docking up my data with an instance held in my containing playfield

wantsRoundedCorners

Default response is simple, fast, and false.
May be overridden to allow almost any morph to be rounded.

Add morph-specific items to the given menu which was invoked by the given hand. This method provides is invoked both from the halo-menu and from the control-menu regimes.

newForm:

releaseCachedState

Release any state that can be recomputed on demand, such as the pixel values for a color gradient or the editor state for a TextMorph. This method may be called to save space when a morph becomes inaccessible. Implementations of this method should do 'super releaseCachedState'.

wearCostume:

parts bin top

initializeToStandAlone

Set up the receiver, created by a #basicNew and now ready to be initialized, as a fully-formed morph suitable for providing a graphic for a parts bin surrogate, and, when such a parts-bin surrogate is clicked on, for attaching to the hand as a viable stand-alone morph. Because of historical precedent, #initialize has been expected to handle this burden, though a great number of morphs actually cannot stand alone. In any case, by default we call the historical #initialize, though unhappily, so that all existing morphs will work no worse than before when using this protocol.

descriptionForPartsBin

If the receiver is a member of a class that would like to be represented in a parts bin, answer the name by which it should be known, and a documentation string to be provided, for example, as balloon help. When the 'nativitySelector' is sent to the 'globalReceiver', it is expected that some kind of Morph will result. The parameters used in the implementation below are for documentation purposes only!
