SVGTransform (GWT Elemental 2.7.0)

All Known Implementing Classes:

JsSVGTransform
```
public interface SVGTransform
```
SVGTransform is the interface for one of the component transformations within an SVGTransformList ; thus, an SVGTransform object corresponds to a single component (e.g., scale(…) or matrix(…)) within a transform attribute.

An SVGTransform object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.

    The unit type is not one of predefined unit types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.

  - getAngle
```
float getAngle()
```
    A convenience attribute for SVG_TRANSFORM_ROTATE, SVG_TRANSFORM_SKEWX and SVG_TRANSFORM_SKEWY. It holds the angle that was specified.
    
    For SVG_TRANSFORM_MATRIX, SVG_TRANSFORM_TRANSLATE and SVG_TRANSFORM_SCALE, angle will be zero.
  - getMatrix
```
SVGMatrix getMatrix()
```
    The matrix that represents this transformation. The matrix object is live, meaning that any changes made to the SVGTransform object are immediately reflected in the matrix object and vice versa. In case the matrix object is changed directly (i.e., without using the methods on the SVGTransform interface itself) then the type of the SVGTransform changes to SVG_TRANSFORM_MATRIX.
    - For SVG_TRANSFORM_MATRIX, the matrix contains the a, b, c, d, e, f values supplied by the user.
    - For SVG_TRANSFORM_TRANSLATE, e and f represent the translation amounts (a=1, b=0, c=0 and d=1).
    - For SVG_TRANSFORM_SCALE, a and d represent the scale amounts (b=0, c=0, e=0 and f=0).
    - For SVG_TRANSFORM_SKEWX and SVG_TRANSFORM_SKEWY, a, b, c and d represent the matrix which will result in the given skew (e=0 and f=0).
    - For SVG_TRANSFORM_ROTATE, a, b, c, d, e and f together represent the matrix which will result in the given rotation. When the rotation is around the center point (0, 0), e and f will be zero.
  - getType
```
int getType()
```
    The type of the value as specified by one of the SVG_TRANSFORM_* constants defined on this interface.
  - setRotate
```
void setRotate(float angle,
               float cx,
               float cy)
```
    Sets the transform type to SVG_TRANSFORM_ROTATE, with parameter angle defining the rotation angle and parameters cx and cy defining the optional center of rotation.
    
    Exceptions:
    - a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when attempting to modify a read only attribute or when the object itself is read only.
  - setScale
```
void setScale(float sx,
              float sy)
```
    Sets the transform type to SVG_TRANSFORM_SCALE, with parameters sx and sy defining the scale amounts.
    
    Exceptions:
    - a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when attempting to modify a read only attribute or when the object itself is read only.
  - setSkewX
```
void setSkewX(float angle)
```
    Sets the transform type to SVG_TRANSFORM_SKEWX, with parameter angle defining the amount of skew.
    
    Exceptions:
    - a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when attempting to modify a read only attribute or when the object itself is read only.
  - setSkewY
```
void setSkewY(float angle)
```
    Sets the transform type to SVG_TRANSFORM_SKEWY, with parameter angle defining the amount of skew.
    
    Exceptions:
    - a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when attempting to modify a read only attribute or when the object itself is read only.
  - setTranslate
```
void setTranslate(float tx,
                  float ty)
```
    Sets the transform type to SVG_TRANSFORM_TRANSLATE, with parameters tx and ty defining the translation amounts.
    
    Exceptions:
    - a DOMException with code NO_MODIFICATION_ALLOWED_ERR is raised when attempting to modify a read only attribute or when the object itself is read only.
