GetPixels(int, int)
Gets the pixel color data for a mipmap level of a slice as Color structs.
public Color[] GetPixels(int arrayElement, int miplevel)
Parameters
The array slice to read pixel data from.
The mipmap level to get. The range is through the texture's Texture.mipmapCount. The default value is .
00Returns
Type | Description |
|---|---|
| Color[] | An array that contains the pixel colors. |
Remarks
This method gets pixel data from the texture in CPU memory. Texture.isReadable must be .
trueThe 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 mipmap level.
Each pixel is a Color struct. might be slower than some other texture methods because it converts the format the texture uses into Color. also needs to decompress compressed textures, and use memory to store the decompressed area. To get pixel data more quickly, use Texture2DArray.GetPixelData instead.
GetPixelsGetPixelsIf fails, Unity throws an exception. might fail if the array contains too much data. Use Texture2DArray.GetPixelData instead for very large textures.
GetPixelsGetPixelsYou can't use with textures that use Crunch texture compression. Use Texture2DArray.GetPixels32 instead.
GetPixelusing UnityEngine;public class Texture2DArrayExample : MonoBehaviour{ public Texture2DArray source; public Texture2DArray destination; void Start() { // Get a copy of the color data from the source Texture2DArray, in high-precision float format. // Each element in the array represents the color data for an individual pixel. int sourceSlice = 0; int sourceMipLevel = 0; Color[] pixels = source.GetPixels(sourceSlice, sourceMipLevel); // If required, manipulate the pixels before applying them to the destination Texture2DArray. // This example code reverses the array, which rotates the image 180 degrees. System.Array.Reverse(pixels, 0, pixels.Length); // Set the pixels of the destination Texture2DArray. int destinationSlice = 0; int destinationMipLevel = 0; destination.SetPixels(pixels, destinationSlice, destinationMipLevel); // Apply changes to the destination Texture2DArray, which uploads its data to the GPU. destination.Apply(); }}
