LocalHistogramEqualizeCommand Constructor(Int32,Int32,Int32,Int32,Int32,HistogramEqualizeType)
See Also  Example



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.
Initializes a new LocalHistogramEqualizeCommand class object with explicit parameters.

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.
