Field Details

width

protected double width

Computed width and height of the node after scaling (not absolute value).

height

protected double height

Computed width and height of the node after scaling (not absolute value).

svg

protected String svg

Computed SVG content of the node after scaling.

Constructor Details

Scale

public Scale(double scaleX,
 double scaleY)

Constructor.

Parameters:

scaleX - X scale factor (Zero means, as per the aspect ratio).

scaleY - Y scale factor (Zero means, as per the aspect ratio).

Method Details

compute

protected void compute(Node node)

Compute the width, height, and SVG content of the node.

Parameters:

node - The node to be scaled.

transformX1

public double transformX1(Node node)

Description copied from interface: Transformer

Transform the X1 coordinate.

Note: This is the first method invoked while transforming a node. It is used to adjust the starting X coordinate of the node.

Specified by:

transformX1 in interface Transformer

Parameters:

node - Node to transform.

Returns:

Transformed X1 coordinate.

transformX2

public double transformX2(Node node)

Description copied from interface: Transformer

Transform the X2 coordinate.

Note: This is the 3rd method invoked while transforming a node. It is used to adjust the ending X coordinate of the node.

Specified by:

transformX2 in interface Transformer

Parameters:

node - Node to transform.

Returns:

Transformed X2 coordinate.

transformY2

public double transformY2(Node node)

Description copied from interface: Transformer

Transform the Y2 coordinate.

Note: This is the 4th method invoked while transforming a node. It is used to adjust the ending Y coordinate of the node.

Specified by:

transformY2 in interface Transformer

Parameters:

node - Node to transform.

Returns:

Transformed Y2 coordinate.

transform

public String transform(Node node)

Description copied from interface: Transformer

Transform the node content.

Note: This is the last method invoked while transforming a node. It is used to adjust the content of the node.

Specified by:

transform in interface Transformer

Parameters:

node - Node to transform.

Returns:

Transformed node content.

scale

protected void scale(Node node,
 double sX,
 double sY)

Do the scaling.

Parameters:

node - Node to scale.

sX - Scale factor for X (zero if it is as per aspect ratio).

sY - Scale factor for Y (zero if it is as per aspect ratio).
