face | The CubemapFace to read pixel data from. |
arrayElement | The array slice to read pixel data from. |
miplevel | The mipmap level to get. The range is 0 through the texture's Texture.mipmapCount. The default value is 0 . |
Color32[] An array that contains the pixel colors.
Gets the pixel color data for a mipmap level of a face of a slice as Color32 structs.
This method gets pixel data from the texture in CPU memory. Texture.isReadable must be true
.
The array contains the pixels row by row, starting at the bottom left of the face texture. The size of the array is the width × height of the mipmap level.
Each pixel is a Color32 struct. GetPixels32
might be slower than some other texture methods because it converts the format the texture uses into Color32. To get pixel data more quickly, use GetPixelData instead.
If GetPixels32
fails, Unity throws an exception. GetPixels32
might fail if the array contains too much data. Use GetPixelData instead for very large textures.
using UnityEngine;
public class CubemapArrayExample : MonoBehaviour { public CubemapArray source; public CubemapArray destination;
void Start() { // Get a copy of the color data from the source CubemapArray, in lower-precision int format. // Each element in the array represents the color data for an individual pixel. CubemapFace sourceFace = CubemapFace.PositiveX; int sourceSlice = 0; int sourceMipLevel = 0; Color32[] pixels = source.GetPixels32(sourceFace, sourceSlice, sourceMipLevel);
// If required, manipulate the pixels before applying them to the destination texture. // 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 CubemapArray. CubemapFace destinationFace = CubemapFace.PositiveX; int destinationSlice = 0; int destinationMipLevel = 0; destination.SetPixels32(pixels, destinationFace, destinationSlice, destinationMipLevel);
// Apply changes to the destination CubemapArray, which uploads its data to the GPU. destination.Apply(); } }
