Class GraphicsConfigurationWithTransparency

  • public class GraphicsConfigurationWithTransparency
extends AbstractGraphicsConfiguration
    An implementation of GraphicsConfiguration that supports transparencies (alpha channels).

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      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).
