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 a 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
