public class GraphicsConfigurationWithTransparency
extends AbstractGraphicsConfiguration

An implementation of GraphicsConfiguration that supports transparencies (alpha channels).


Constructor Summary
GraphicsConfigurationWithTransparency()
           
 
Method Summary
 java.awt.image.BufferedImage createCompatibleImage(int width, int height)
          Construct a buffered image with an alpha channel.
 java.awt.image.BufferedImage createCompatibleImage(int width, int height, int transparency)
          Construct a buffered image with an alpha channel, unless transparency is OPAQUE (no alpha at all).
 java.awt.Rectangle getBounds()
          TODO: This should return the page bounds in Pts, I couldn't figure out how to get this for the current page (this still works for now, but it should be fixed...).
 java.awt.image.ColorModel getColorModel()
          Return a good default color model for this 'device'.
 java.awt.image.ColorModel getColorModel(int transparency)
          Return a good color model given transparency
 java.awt.geom.AffineTransform getDefaultTransform()
          The default transform (1:1).
 java.awt.GraphicsDevice getDevice()
          Return our dummy instance of GraphicsDevice
 java.awt.geom.AffineTransform getNormalizingTransform()
          The normalizing transform (1:1) (since we currently render images at 72dpi, which we might want to change in the future).

Method Detail

createCompatibleImage

public java.awt.image.BufferedImage createCompatibleImage(int width,
                                                          int height,
                                                          int transparency)
Construct a buffered image with an alpha channel, unless transparency is OPAQUE (no alpha at all).

Overrides:
createCompatibleImage in class java.awt.GraphicsConfiguration
Parameters:
width - the width of the image
height - the height of the image
transparency - the alpha value of the image
Returns:
the new buffered image

createCompatibleImage

public java.awt.image.BufferedImage createCompatibleImage(int width,
                                                          int height)
Construct a buffered image with an alpha channel.

Specified by:
createCompatibleImage in class java.awt.GraphicsConfiguration
Parameters:
width - the width of the image
height - the height of the image
Returns:
the new buffered image

getBounds

public java.awt.Rectangle getBounds()
TODO: This should return the page bounds in Pts, I couldn't figure out how to get this for the current page (this still works for now, but it should be fixed...).

Specified by:
getBounds in class java.awt.GraphicsConfiguration
Returns:
the bounds of the document page

getColorModel

public java.awt.image.ColorModel getColorModel()
Return a good default color model for this 'device'.

Specified by:
getColorModel in class java.awt.GraphicsConfiguration
Returns:
the colour model for the configuration

getColorModel

public java.awt.image.ColorModel getColorModel(int transparency)
Return a good color model given transparency

Specified by:
getColorModel in class java.awt.GraphicsConfiguration
Parameters:
transparency - the alpha value for the colour model
Returns:
the colour model for the configuration

getDefaultTransform

public java.awt.geom.AffineTransform getDefaultTransform()
The default transform (1:1).

Specified by:
getDefaultTransform in class java.awt.GraphicsConfiguration
Returns:
the default transform for the configuration

getNormalizingTransform

public java.awt.geom.AffineTransform getNormalizingTransform()
The normalizing transform (1:1) (since we currently render images at 72dpi, which we might want to change in the future).

Specified by:
getNormalizingTransform in class java.awt.GraphicsConfiguration
Returns:
the normalizing transform for the configuration

getDevice

public java.awt.GraphicsDevice getDevice()
Return our dummy instance of GraphicsDevice

Specified by:
getDevice in class java.awt.GraphicsConfiguration
Returns:
the graphics device
