# GetPixels32(Color32[])

> Gets the pixel color data for a mipmap level as Color32 structs.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AudioModule

```csharp
public Color32[] GetPixels32(Color32[] colors)
```

### Parameters

**** (\[Color32\[]]\(/engine/6000.7/script-reference/unityengine/color32)): An optional array to write the pixel data to.

### Returns

| Type                                                                  | Description                              |
| --------------------------------------------------------------------- | ---------------------------------------- |
| [Color32\[\]](/engine/6000.7/script-reference/unityengine/color32.md) | An array that contains the pixel colors. |

### Remarks

This method gets pixel data from the texture in CPU memory. [\_isReadable](/engine/6000.7/script-reference/unityengine/texture/isreadable.md) must be `true`.

The array contains the pixels row by row, starting at the bottom left of the texture. The size of the array is the width × height of the texture.

Each pixel is a [Color32](/engine/6000.7/script-reference/unityengine/color32.md) struct.

A single call to `GetPixels32` is usually faster than multiple calls to [WebCamTexture.GetPixel](/engine/6000.7/script-reference/unityengine/webcamtexture/getpixel.md), especially for large textures.

If `GetPixels32` fails, Unity throws an exception. `GetPixels32` might fail if the array contains too much data.

You can optionally pass in an array of [Color32](/engine/6000.7/script-reference/unityengine/color32.md) structs to avoid allocating new memory each frame. This can improve performance if you are continuously reading data from the camera. The array must be initialized to the dimensions `width * height` of the texture. If you don't pass an array, Unity will allocate one and return it.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    WebCamTexture webcamTexture;
    Color32[] data;

    void Start()
    {
        // Start web cam feed
        webcamTexture = new WebCamTexture();
        webcamTexture.Play();
        data = new Color32[webcamTexture.width * webcamTexture.height];
    }

    void Update()
    {
        webcamTexture.GetPixels32(data);
        // Do processing of data here.
    }
}
```
