.. _BitmapConversionType: ================================================ BitmapConversionType ================================================ Description ----------- The quality of an image converted to bitmap mode. Static Properties ^^^^^^^^^^^^^^^^^ +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`CUSTOMPATTERN` readonly | Simulates the effect of printing a grayscale image through a custom halftone screen. This method lets you apply a screen texture, such as a wood grain, to an image. To use this option, you must first define a pattern. | +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`DIFFUSIONDITHER` readonly | Applies a random pattern that is usually less noticeable than pattern dither. The dither effects are diffused across adjacent pixels. If you select this algorithm, specify a dither percentage to control the amount of dithering applied to the image. | +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`HALFTHRESHOLD` readonly | 50% Threshold. | +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`HALFTONESCREEN` readonly | Lets you convert a grayscale image to simulated halftone dots. | +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`PATTERNDITHER` readonly | Applies a halftone-like square pattern to determine the value of pixels. | +-----------------------------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ .. container:: hide .. toctree:: :hidden: :maxdepth: 1 BitmapConversionType/HALFTHRESHOLD.rst BitmapConversionType/PATTERNDITHER.rst BitmapConversionType/DIFFUSIONDITHER.rst BitmapConversionType/HALFTONESCREEN.rst BitmapConversionType/CUSTOMPATTERN.rst
