## Class JAIMonochromeBitmapConverter

- java.lang.Object
- - org.apache.fop.util.bitmap.JAIMonochromeBitmapConverter

- All Implemented Interfaces:
    MonochromeBitmapConverter

      public class JAIMonochromeBitmapConverter
      extends java.lang.Object
      implements MonochromeBitmapConverter

  Implementation of the MonochromeBitmapConverter which uses Java Advanced Imaging (JAI) to convert grayscale bitmaps to monochrome bitmaps. JAI provides better dithering options including error diffusion dithering.

  If you call setHint("quality", "true") on the instance you can enabled error diffusion dithering which produces a nicer result but is also a lot slower.
