BitmapStatisticsProvider Class

This class contains methods used by Bitmap to retrieve various bitmap statistics.

Namespace: Aurigma.GraphicsMill
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public Class BitmapStatisticsProvider _
	Inherits LockableObject

C#

public class BitmapStatisticsProvider : LockableObject

Main feature of this class is possibility to calculate bitmap histogram. Histogram is an array of values that specify how much pixels has a luminosity (or other value that specifies pixel brightness level) equal to appropriate array index. It can be either calculated as histogram of bitmap luminosity (GetLuminosityHistogram()()() method), or histogram of the channels sum (GetSumHistogram(Boolean) method). Last method is used in Adobe® Photoshop® by default.

Examples

Visual Basic

Dim histogram As Aurigma.GraphicsMill.Histogram = _
 bitmap.Statistics.GetSumHistogram(False)

For i As Integer = 0 To histogram.Length - 1
    Console.WriteLine(i & ": " & histogram(i))
Next

C#

Aurigma.GraphicsMill.Histogram histogram =
    bitmap.Statistics.GetSumHistogram(false);

for (int i = 0; i < histogram.Length; i++)
{
    Console.WriteLine(i + ": " + histogram[i]);
}
