This class converts an image into a black and white image without changing its bits per pixel. Each pixel is compared to a dynamically-calculated threshold. If the intensity of the pixel is higher (that is, the pixel is brighter) than the dynamic threshold, the pixel will be set to white. If the intensity of the pixel is lower (that is, the pixel is darker) than the dynamic threshold, the pixel will be set to black. Here are some hints on using this class: Increasing the LocalContrast property increases the number of pixels that use the global threshold. This tends to preserve the general aspect of the image and reduces the improvement in the areas with many details. Reducing the LocalContrast property, increases the contrast in areas with many details. Increasing the Dimension property increases the area used for local contrast. This makes the color changes smoother. This class is good as a prerequisite for converting scanned images to 1-bit, because it uses one threshold for background and another for text. This command does not support signed data images.
