Constructors| Name | Description | |
|---|---|---|
 | Histogram(AtalaImage) | Initializes a new instance of the Histogram object. |
| Histogram(AtalaImage, ProgressEventHandler) | Initializes a new instance of the Histogram object. |
| Histogram(AtalaImage, Rectangle) | Creates a new instance of Histogram specifying the image to examine and a specific rectangular area of the
image to work with. |
| Histogram(AtalaImage, Rectangle, ProgressEventHandler) | Creates an instance of Histogram specifying the image to examine, a selection of the image to work with
and the progress event handler. |

 | Area | Gets or sets a rectangular area of the image the histogram methods will work with. |
| Image | Gets or sets the image to evaluate. |
| Progress | Gets or sets the progress delegate. |

| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetBrightnessHistogram | Returns an array containing a histogram of brightness values in the image. |
| GetChannelHistogram | Returns an array containing a histogram of color values from a particular channel in the image. |
| GetDocumentHistogram | Returns a two element array containing the number of black and white pixels in a binary image. |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
