1 Select the bitmap with the Pick tool.
2 Click Bitmaps, Mode, Black And White (1-bit).
3 In the Conversion list box, choose a type of conversion from Line Art, Ordered, Halftone, Cardinality-Distribution, Jarvis, Stucki, or Floyd-Steinberg.
4 If you choose Halftone, do all of the following:
• Set a level of intensity using the Intensity slider.
• Choose a screen type from the Screen Type list box.
• Choose a unit from the list and type a value in the Lines per box to control the line frequency.
• Type a value in the Degrees box to control the screen angle.
5 If you choose Line Art, type a value in the Threshold box.
All colors with a grayscale value lower than this threshold value change to black; all colors with a grayscale value higher than the threshold value change to white.
6 If you choose Ordered, Jarvis, Stucki, Floyd-Steinberg, or Cardinality-Distribution, set a level of intensity using the Intensity slider.
Higher Intensity values result in more and darker grayscale tones; lower intensity values result in less, lighter grayscale tones.
