  • Method Details

    • createCompatibleImage

      public 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 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 BufferedImage createCompatibleImage(int width, int height)
      Construct a buffered image with an alpha channel.
      Overrides:
      createCompatibleImage in class GraphicsConfiguration
      Parameters:
      width - the width of the image
      height - the height of the image
      Returns:
      the new buffered image

    • getBounds

      public 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 GraphicsConfiguration
      Returns:
      the bounds of the document page

    • getColorModel

      public ColorModel getColorModel()
      Return a good default color model for this 'device'.
      Specified by:
      getColorModel in class GraphicsConfiguration
      Returns:
      the colour model for the configuration

    • getColorModel

      public ColorModel getColorModel(int transparency)
      Return a good color model given transparency
      Specified by:
      getColorModel in class GraphicsConfiguration
      Parameters:
      transparency - the alpha value for the colour model
      Returns:
      the colour model for the configuration

    • getDefaultTransform

      public AffineTransform getDefaultTransform()
      The default transform (1:1).
      Specified by:
      getDefaultTransform in class GraphicsConfiguration
      Returns:
      the default transform for the configuration

    • getNormalizingTransform

      public 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 GraphicsConfiguration
      Returns:
      the normalizing transform for the configuration

    • getDevice

      public GraphicsDevice getDevice()
      Return our dummy instance of GraphicsDevice
      Specified by:
      getDevice in class GraphicsConfiguration
      Returns:
      the graphics device
