# SVGShape Class

Defined in: `graphics/js/SVGShape.js:1`
Module: graphics

SVG implementation of the `Shape` class. `SVGShape` is not intended to be used directly. Instead, use the `Shape` class. If the browser has SVG capabilities, the `Shape` class will point to the `SVGShape` class.

## Attributes

### `data`

String

Defined in `graphics/js/SVGShape.js:1225`

Represents an SVG Path string. This will be parsed and added to shape's API to represent the SVG data across all implementations. Note that when using VML or SVG implementations, part of this content will be added to the DOM using respective VML/SVG attributes. If your content comes from an untrusted source, you will need to ensure that no malicious code is included in that content.

### `fill`

Object

Defined in `graphics/js/SVGShape.js:1069`

Contains information about the fill of the shape.

color
  The color of the fill.
opacity
  Number between 0 and 1 that indicates the opacity of the fill. The default value is 1.
type
  Type of fill.
  solid
    Solid single color fill. (default)
  linear
    Linear gradient fill.
  radial
    Radial gradient fill.

If a `linear` or `radial` is specified as the fill type. The following additional property is used:

stops
  An array of objects containing the following properties:
  color
    The color of the stop.
  opacity
    Number between 0 and 1 that indicates the opacity of the stop. The default value is 1. Note: No effect for IE 6 - 8
  offset
    Number between 0 and 1 indicating where the color stop is positioned.

Linear gradients also have the following property:

rotation
  Linear gradients flow left to right by default. The rotation property allows you to change the flow by rotation. (e.g. A rotation of 180 would make the gradient pain from right to left.)

Radial gradients have the following additional properties:

r
  Radius of the gradient circle.
fx
  Focal point x-coordinate of the gradient.
fy
  Focal point y-coordinate of the gradient.
cx

  The x-coordinate of the center of the gradient circle. Determines where the color stop begins. The default value 0.5.

  Note: Currently, this property is not implemented for corresponding `CanvasShape` and `VMLShape` classes which are used on Android or IE 6 - 8.

cy

  The y-coordinate of the center of the gradient circle. Determines where the color stop begins. The default value 0.5.

  Note: Currently, this property is not implemented for corresponding `CanvasShape` and `VMLShape` classes which are used on Android or IE 6 - 8.

### `graphic`

SVGGraphic readonly

Defined in `graphics/js/SVGShape.js:1245`

Reference to the parent graphic instance

### `height`

Number

Defined in `graphics/js/SVGShape.js:1040`

Indicates the height of the shape

### `id`

String

Defined in `graphics/js/SVGShape.js:961`

Unique id for class instance.

### `node`

HTMLElement readonly

Defined in `graphics/js/SVGShape.js:1209`

Dom node for the shape.

### `stroke`

Object

Defined in `graphics/js/SVGShape.js:1133`

Contains information about the stroke of the shape.

color
  The color of the stroke.
weight
  Number that indicates the width of the stroke.
opacity
  Number between 0 and 1 that indicates the opacity of the stroke. The default value is 1.
dashstyle
Indicates whether to draw a dashed stroke. When set to "none", a solid stroke is drawn. When set to an array, the first index indicates the length of the dash. The second index indicates the length of gap.
linecap
  Specifies the linecap for the stroke. The following values can be specified:
  butt (default)
    Specifies a butt linecap.
  square
    Specifies a sqare linecap.
  round
    Specifies a round linecap.
linejoin
  Specifies a linejoin for the stroke. The following values can be specified:
  round (default)
    Specifies that the linejoin will be round.
  bevel
    Specifies a bevel for the linejoin.
  miter limit
    An integer specifying the miter limit of a miter linejoin. If you want to specify a linejoin of miter, you simply specify the limit as opposed to having separate miter and miter limit values.

### `transform`

String

Defined in `graphics/js/SVGShape.js:915`

A string containing, in order, transform operations applied to the shape instance. The `transform` string can contain the following values:

rotate
  Rotates the shape clockwise around it transformOrigin.
translate
  Specifies a 2d translation.
skew
  Skews the shape around the x-axis and y-axis.
scale
  Specifies a 2d scaling operation.
translateX
  Translates the shape along the x-axis.
translateY
  Translates the shape along the y-axis.
skewX
  Skews the shape around the x-axis.
skewY
  Skews the shape around the y-axis.
matrix
  Specifies a 2D transformation matrix comprised of the specified six values.

Applying transforms through the transform attribute will reset the transform matrix and apply a new transform. The shape class also contains corresponding methods for each transform that will apply the transform to the current matrix. The below code illustrates how you might use the `transform` attribute to instantiate a recangle with a rotation of 45 degrees.

           var myRect = new Y.Rect({
               type:"rect",
               width: 50,
               height: 40,
               transform: "rotate(45)"
           };

The code below would apply `translate` and `rotate` to an existing shape.

       myRect.set("transform", "translate(40, 50) rotate(45)");

### `transformOrigin`

Array

Defined in `graphics/js/SVGShape.js:901`

### `x`

Number

Defined in `graphics/js/SVGShape.js:984`

Indicates the x position of shape.

### `y`

Number

Defined in `graphics/js/SVGShape.js:1007`

Indicates the y position of shape.
