VML implementation of the Graphic
class.
VMLGraphic
is not intended to be used directly. Instead, use the Graphic
class.
If the browser lacks SVG and Canvas
capabilities, the Graphic
class will point to the VMLGraphic
class.

batch
method
Allows for creating multiple shapes in order to batch appending and redraw operations.
method
Function

clear
Clears the graphics object.
destroy
Removes all nodes.
getShapeById
id
Returns a shape based on the id of its dom node.
id
String
Dom id of the shape's node attribute.
Shape
getXY
Gets the current position of the graphic instance in page coordinates.
Array The XY position of the shape.

_shapeClass
Look up for shape classes. Used by addShape
to retrieve a class for instantiation.
autoDraw
Indicates whether or not the instance will automatically redraw after a change is made to a shape. This property will get set to false when batching operations.
Default: true
autoSize
Determines the sizing of the Graphic.
width
and height
attributes or are determined by the dimensions of the parent element. The
content contained in the Graphic will be sized to fit with in the Graphic instance's dimensions. When using this
setting, the preserveAspectRatio
attribute will determine how the contents are sized.width
and height
attributes or are determined by the dimensions of the parent element. The contents of the
Graphic instance are not affected by this setting.Default: false
contentBounds
Object containing size and coordinate data for the content of a Graphic in relation to the coordSpace node.
preserveAspectRatio
Determines how content is sized when autoSize
is set to sizeContentToGraphic
.
Default: xMidYMid
render
Whether or not to render the Graphic
automatically after to a specified parent node after init. This can be a Node
instance or a CSS selector string.
resizeDown
The contentBounds will resize to greater values but not values. (for performance) When resizing the contentBounds down is desirable, set the resizeDown value to true.
