```csharp
class ICCBasedColorSpace : ColorSpace
```

**Namespace:** `Datalogics::PDFL`

**Inherits from:** [`ColorSpace`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/ColorSpace.md)

## Description

Works with the ICC color space.

The International Color Consortium (ICC) developed the ICC color space in 1993 to serve as a universal standard for for printing or presenting content with digital devices, and across all operating systems and platforms.

The ICC color standard applies regardless the hardware or software involved, and is used to make sure that color images and text appear properly on a wide variety of platforms.

**Uses types:** [`ColorSpace`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/ColorSpace.md), [`PDFObject`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFObject.md), [`PDFStream`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFStream.md)

## Constructors

### ICCBasedColorSpace

```csharp
Datalogics.PDFL.ICCBasedColorSpace.ICCBasedColorSpace(PDFStream iccStream)
```

*constructor*

**Parameters**

- `iccStream` ([`PDFStream`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFStream.md)): stream containing the ICC profile

Create an ICC-based color stream.

### ICCBasedColorSpace

```csharp
Datalogics.PDFL.ICCBasedColorSpace.ICCBasedColorSpace(PDFStream iccStream, int nComps)
```

*constructor*

**Parameters**

- `iccStream` ([`PDFStream`](https://docs.datalogics.com/apdfl21/DotNetFramework/APDFL21.0.0PlusP1e/class/PDFStream.md)): stream containing the ICC profile
- `nComps` (`int`): The number of components (1, 3, or 4)

Create an ICC-based color stream.

## Properties

### Alternate

```csharp
ColorSpace Datalogics.PDFL.ICCBasedColorSpace.Alternate { get; set; }
```

An alternate color space to be used in case the one specified in the stream data is not supported (for example, by applications designed for earlier versions of PDF). The alternate space may be any valid color space (except a Pattern color space) that has the number of components specified by N. If this entry is omitted and the application does not understand the ICC profile data, the color space used is DeviceGray, DeviceRGB, or DeviceCMYK, depending on whether the value of N is 1, 3, or 4, respectively.

### DeviceCMYK

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.DeviceCMYK { get; }
```

*static*

The DeviceCMYK color space, representing cyan, magenta, yellow, and black components.

### DeviceGray

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.DeviceGray { get; }
```

*static*

The DeviceGray color space, representing a single grayscale component.

### DeviceRGB

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.DeviceRGB { get; }
```

*static*

The DeviceRGB color space, representing red, green, and blue components.

### DeviceRGBA

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.DeviceRGBA { get; }
```

*static*

The DeviceRGBA color space, representing red, green, blue, and alpha components.

### Lab

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.Lab { get; }
```

*static*

The CIE-based L*a*b* color space.

### LabA

```csharp
static ColorSpace Datalogics.PDFL.ColorSpace.LabA { get; }
```

*static*

The CIE-based L*a*b* color space with an alpha component.

### Name

```csharp
string Datalogics.PDFL.ColorSpace.Name { get; }
```

The name of the color space. A named color space may be named something like DeviceRGB. More complicated color spaces may have a name like Indexed or ICCBased.

### NumComponents

```csharp
int Datalogics.PDFL.ColorSpace.NumComponents { get; }
```

The number of components in the color space.

For example, DeviceGray has 1 component, DeviceRGB has 3, and DeviceCMYK has 4.

### PDFObject

```csharp
PDFObject Datalogics.PDFL.ColorSpace.PDFObject { get; }
```

Get the PDFObject associated with the color space. This may be a PDFName, PDFDict, PDFStream, or PDFArray.

### Range

```csharp
System.Collections.Generic.IList<System.Double> Datalogics.PDFL.ICCBasedColorSpace.Range { get; set; }
```

An array of 2 * NumComponents numbers [ min0 max0 min1 max1 ... ] specifying the minimum and maximum valid values of the corresponding color components. These values must match the information in the ICC profile. Default value: [ 0.0 1.0 0.0 1.0 ... ]

### Stream

```csharp
PDFStream Datalogics.PDFL.ICCBasedColorSpace.Stream { get; }
```

The PDFStream containing the ICC-based data and other attributes.

## Methods

### Dispose
