# BitmapStatisticsProvider Class
 
Contains methods used to retrieve various bitmap statistics.
 
**Namespace:** [Aurigma.GraphicsMill](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public sealed class BitmapStatisticsProvider
```
 
## Remarks
 This class is accessible via the [Bitmap.Statistics](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Bitmap_Statistics.htm.md) property. Its main feature is the ability to calculate a bitmap histogram. A 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()](https://www.graphicsmill.com/docs/gm/M_Aurigma_GraphicsMill_BitmapStatisticsProvider_GetLuminosityHistogram.htm.md) method) or histogram of the channels sum ([GetSumHistogram()](https://www.graphicsmill.com/docs/gm/M_Aurigma_GraphicsMill_BitmapStatisticsProvider_GetSumHistogram.htm.md) method). Last method is used in Adobe® Photoshop® by default.
 
## Examples
  
```csharp
var histogram = bitmap.Statistics.GetSumHistogram();
for (int i = 0; i < histogram.Length; i++)
{
    Console.WriteLine(i + ": " + histogram[i]);
}
```
