  visual.statik.AbstractTransformableContent
      visual.statik.sampled.Content

All Implemented Interfaces:

SimpleContent, TransformableContent

public class Content
extends AbstractTransformableContent
implements TransformableContent

A BufferedImage that knows how to render itself (i.e., a BufferedImage along with all of the attributes necessary for rendering)

Explicit Value Constructor

Content(java.awt.image.BufferedImage image, double x, double y, boolean rotating)
Explicit Value Constructor

Method Summary

java.awt.geom.Rectangle2D	getBounds2D() Returns a high precision bounding box of the appropriately transformed content
java.awt.geom.Rectangle2D	getBounds2D(boolean transformed) Returns a high precision bounding box of the Content either before or after it is transformed (required by TransformedContent)
protected boolean	isTransformationRequired() Does this AbstractTransformableContent object need to be transformed before being used?
void	render(java.awt.Graphics g) Render this sampled visual content (required by Content)
void	setBufferedImageOp(java.awt.image.BufferedImageOp op) Set the BufferedImageOp to use when transforming the Image
void	setComposite(java.awt.Composite c) Set the transparency/Composite
void	setImage(java.awt.image.BufferedImage image) Set the BufferedImage
void	setLocation(double x, double y) Set the location Note: This method overrides the version in the parent because the translation of sampled content does not require transformation
void	setRotation(double angle, double x, double y) Set the rotation Note: This method overrides the version in the parent because efficiency can be improved when rotations are prevented
protected void	setTransformationRequired(boolean required) Set whether this AbstractTransformableContent object needs to be transformed before being used

Constructor Detail

Content

public Content()

Default Constructor

Content

public Content(java.awt.image.BufferedImage image,
               double x,
               double y)

Explicit Value Constructor

Parameters:

image - The BufferedImage

x - The coordinate of the left edge

y - The coordinate of the top edge

Content

public Content(java.awt.image.BufferedImage image,
               double x,
               double y,
               boolean rotating)

Explicit Value Constructor

Parameters:

image - The BufferedImage

x - The coordinate of the left edge

y - The coordinate of the top edge

rotating - false to prevent rotations (and improve performance)

Method Detail

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D()

Returns a high precision bounding box of the appropriately transformed content

Overrides:

getBounds2D in class AbstractTransformableContent

Returns:

The bounding box

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D(boolean transformed)

Returns a high precision bounding box of the Content either before or after it is transformed (required by TransformedContent)

Specified by:

getBounds2D in interface TransformableContent

Specified by:

getBounds2D in class AbstractTransformableContent

Parameters:

transformed - true to get the BB of the transformed content

Returns:

The bounding box

render

public void render(java.awt.Graphics g)

Render this sampled visual content (required by Content)

Specified by:

render in interface SimpleContent

Parameters:

g - The rendering engine to use

setImage

public void setImage(java.awt.image.BufferedImage image)

Set the BufferedImage

Parameters:

image - The BufferedImage (or null to render nothing)

setBufferedImageOp

public void setBufferedImageOp(java.awt.image.BufferedImageOp op)

Set the BufferedImageOp to use when transforming the Image

Parameters:

op - The BufferedImageOp

setComposite

public void setComposite(java.awt.Composite c)

Set the transparency/Composite

Parameters:

c - The Composite

setLocation

public void setLocation(double x,
                        double y)

Set the location Note: This method overrides the version in the parent because the translation of sampled content does not require transformation

Specified by:

setLocation in interface TransformableContent

Overrides:

setLocation in class AbstractTransformableContent

Parameters:

x - The x position

y - The y position

setRotation

public void setRotation(double angle,
                        double x,
                        double y)

Set the rotation Note: This method overrides the version in the parent because efficiency can be improved when rotations are prevented

Specified by:

setRotation in interface TransformableContent

Overrides:

setRotation in class AbstractTransformableContent

Parameters:

angle - The rotation angle

x - The x-coordinate of the point to rotate around

y - The y-coordinate of the point to rotate around

setTransformationRequired

protected void setTransformationRequired(boolean required)

Set whether this AbstractTransformableContent object needs to be transformed before being used

Overrides:

setTransformationRequired in class AbstractTransformableContent

Parameters:

required - true to indicate that a transformation is requried

isTransformationRequired

protected boolean isTransformationRequired()

Does this AbstractTransformableContent object need to be transformed before being used?

Overrides:

isTransformationRequired in class AbstractTransformableContent

Returns:

true to indicate a transformation is required
