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

| --- | --- | --- |
|  | [{dtor}](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_%7Bdtor%7D.htm.md) | Enables using delete operator in C++ applications. It is strongly not recommended to use it directly. |
|  | [BuildEmpty](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildEmpty_1_ea7b1ae4.htm.md) | Resets all LUT entries to zero. |
|  | [BuildFromArray](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildFromArray_1_a56295c4.htm.md) | Builds a LUT from specified array. |
|  | [BuildFromBitmapHistogram](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildFromBitmapHistogram_1_fd4033ef.htm.md) | Builds a LUT which would make histogram of the specified bitmap as uniform as possible. |
|  | [BuildFromGamma](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildFromGamma_2_6c54b22f.htm.md) | Builds a LUT which makes the gamma correction. |
|  | [BuildFromSpline](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildFromSpline_2_77a5e52f.htm.md) | Builds LUT defined as a curve which passes specified set of points. |
|  | [BuildIdentical](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildIdentical_1_ea7b1ae4.htm.md) | Builds an *identical* LUT, i.e. a LUT which does not modify the source image. |
|  | [BuildLinear](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildLinear_3_0ac4a004.htm.md) | Builds a LUT from linear function with given parameters. |
|  | [BuildStaircase](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Lut_BuildStaircase_2_2ffe03ff.htm.md) | Builds a LUT from a staircase function with a given number of steps. |
