Constructor Detail

StandardGradientPaintTransformer

public StandardGradientPaintTransformer()
Creates a new transformer with the type GradientPaintTransformType.VERTICAL.


StandardGradientPaintTransformer

public StandardGradientPaintTransformer(GradientPaintTransformType type)
Creates a new transformer with the specified type.

Parameters:
type - the transform type (null not permitted).
Method Detail

getType

public GradientPaintTransformType getType()
Returns the type of transform.

Returns:
The type of transform (never null).
Since:
1.0.10

transform

public java.awt.GradientPaint transform(java.awt.GradientPaint paint,
                                        java.awt.Shape target)
Transforms a GradientPaint instance to fit the specified target shape.

Specified by:
transform in interface GradientPaintTransformer
Parameters:
paint - the original paint (null not permitted).
target - the target shape (null not permitted).
Returns:
The transformed paint.

equals

public boolean equals(java.lang.Object obj)
Tests this instance for equality with an arbitrary object.

Overrides:
equals in class java.lang.Object
Parameters:
obj - the object (null permitted).
Returns:
A boolean.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
Returns a clone of the transformer. Note that instances of this class are immutable, so cloning an instance isn't really necessary.

Specified by:
clone in interface PublicCloneable
Overrides:
clone in class java.lang.Object
Returns:
A clone.
Throws:
java.lang.CloneNotSupportedException - not thrown by this class, but subclasses (if any) might.

hashCode

public int hashCode()
Returns a hash code for this object.

Overrides:
hashCode in class java.lang.Object
Returns:
A hash code.
