**Inherits from:** [`ColorSpace`](https://docs.datalogics.com/apdfl18/DotNet/APDFL18.0.5PlusP2e/class/ColorSpace.md)

## Description

Represents a color space with an arbitrary number of color components.

DeviceN color spaces were designed to represent color spaces containing multiple color components that correspond to the colorants of some target device. They provide greater flexibility than is possible with standard device color spaces such as DeviceCMYK or with individual Separation color spaces. For example, it is possible to create a DeviceN color space consisting of only the cyan, magenta, and yellow color components, with the black component excluded.

## Constructors

### DeviceNColorSpace

```csharp
Datalogics.PDFL.DeviceNColorSpace.DeviceNColorSpace(System.Collections.Generic.IList< System.String > names, ColorSpace alternate, Function tintTransform)
```

*constructor*

**Parameters**

- `names` (`System.Collections.Generic.IList< System.String >`): the names of the colorants that the DeviceN space is intended to represent, among which may be All, or None
- `alternate` ([`ColorSpace`](https://docs.datalogics.com/apdfl18/DotNet/APDFL18.0.5PlusP2e/class/ColorSpace.md)): the alternate color space, which can be any device or CIE-based color space but not another special color space (Pattern, Indexed, Separation, or DeviceN).
- `tintTransform` ([`Function`](https://docs.datalogics.com/apdfl18/DotNet/APDFL18.0.5PlusP2e/class/Function.md)): function, called with the tint value and returning the corresponding color component values. That is, the number of components and the interpretation of their values depend on the alternate color space.

Create a DeviceN color space.
