Initializes a new LocalHistogramEqualizeCommand class object with explicit parameters.
Supported in Silverlight, Windows Phone 7
Syntax
Parameters
- width
- The width of the local histogram equalizer rectangle in pixels. The width should be more than zero.
- height
- The height of the local histogram equalizer rectangle in pixels. The height should be more than zero.
- widthExtension
- The extension of the width of the local histogram equalizer rectangle, in pixels.
- heightExtension
- The extension of the height of the local histogram equalizer rectangle, in pixels.
- smooth
- Size of the area to be used when smoothing the edges between localized blocks. Possible values are between 0 and 7, but if Height is less than or equal to 7 then the maximum value for this item is Height - 1. If Smooth = 0 the edges will not be smoothed.
- type
- Flag that indicates which color space to equalize.
Example
Run the LocalHistogramEqualizeCommand on an image.
