| Viewport | | abstract public class Viewport extends CompositeNode implements Transformable(Code) | | A Viewport describes a ModelNode into which
rendering may happen.
A ViewportNode has a width and height
which a child SVG uses to compute the viewbox to viewport
transform.
In addition, a Viewport has a user transform limited to
its scale and translation components.
The Viewport is the root of any SVG fragment hierarchy.

| height | | protected int height(Code) | | Viewport height
|
| inverseTxf | | protected Transform inverseTxf(Code) | | The inverse of the Transform applied to this node.
|
| transform | | protected Transform transform(Code) | | The Transform applied to this node.
|
| width | | protected int width(Code) | | Viewport width
|
| zoomAndPan | | protected int zoomAndPan(Code) | | The zoomAndPan setting
|
| Viewport | | public Viewport()(Code) | | Default constructor
|
| appendTransform | | protected Transform appendTransform(Transform tx, Transform workTx)(Code) | | Appends this node's transform, if it is not null.
Parameters:
tx - the Transform to apply additional node transforms to. This may be null.
Parameters:
workTx - a Transform which can be re-used if a new Transform needs to be created and workTxis not the same instance as tx. a transform with this node's transform added. |
| getHeight | | public int getHeight()(Code) | | the viewport height |
| getInverseTransformState | | public Transform getInverseTransformState()(Code) | | this node's cached inverse transform. |
| getTransform | | public Transform getTransform()(Code) | | This Transformable's transform. |
| getTransformState | | public Transform getTransformState()(Code) | | this node's cached transform. |
| getWidth | | public int getWidth()(Code) | | the viewport width |
| getZoomAndPan | | public int getZoomAndPan()(Code) | | The zoomAndPan setting for this viewport (read-only) |
| nodeHitAt | | public ModelNode nodeHitAt(float[] pt)(Code) | | Returns the ModelNode, if any, hit by the
point at coordinate x/y.
Parameters:
pt - the x/y coordinate. Should never be null and beof size two. If not, the behavior is unspecified.The coordinates are in viewport space. the ModelNode hit at the given point or nullif none was hit. |
| recomputeTransformState | | protected void recomputeTransformState(Transform parentTransform)(Code) | | Recomputes the transform cache, if one exists. This should recursively
call recomputeTransformState on children node or expanded content, if
any.
By default, because a ModelNode has no transform and no cached transform,
this only does a pass down.
Parameters:
parentTransform - the Transform applied to this node's parent. |
| setSize | | public void setSize(int newWidth, int newHeight)(Code) | | Sets the viewport size
Parameters:
newWidth - the new viewport width. Should be greater than 0
Parameters:
newHeight - the new viewport height. Should be greater than 0. |
| setTransform | | public void setTransform(Transform newTransform)(Code) | |
Parameters:
newTransform - The new Transformable's transform. |
| setZoomAndPan | | public void setZoomAndPan(int newZoomAndPan)(Code) | |
Parameters:
newZoomAndPan - the new value for the zoom and pan setting |
