# Histogram Members
The [Histogram](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Histogram.htm.md) type exposes the following members.
## Constructors
| | Name | Description |
| --- | --- | --- |
|  | [Histogram](https://www.graphicsmill.com/docs/gm5/O_T_Aurigma_GraphicsMill_Histogram_ctor.htm.md) | Overloaded.
Creates new [Histogram](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Histogram.htm.md) instance. |

|  | [BuildLuminosity](https://www.graphicsmill.com/docs/gm5/O_T_Aurigma_GraphicsMill_Histogram_BuildLuminosity.htm.md) | Overloaded.
Builds the histogram for specified bitmap. Histogram is based on pixels luminosity. |
|  | [BuildSum](https://www.graphicsmill.com/docs/gm5/O_T_Aurigma_GraphicsMill_Histogram_BuildSum.htm.md) | Overloaded.
Builds the histogram for specified bitmap. Histogram is based on average of pixel channels values. |
