Declaration

public void SetPixels32(Color32[] colors, int arrayElement, int miplevel);

Declaration

public void SetPixels32(Color32[] colors, int arrayElement);

Parameters

colors The array of pixel colours to use. This is a 2D image flattened to a 1D array.
arrayElement The array slice to write colors to.
miplevel The mipmap level to write colors to. The range is 0 through the texture's Texture.mipmapCount. The default value is 0.

Description

Sets the pixel colors of an entire mipmap level of a slice.

This method sets pixel data for the texture in CPU memory. Texture.isReadable must be true, and you must call Apply after SetPixels32 to upload the changed pixels to the GPU.

colors must contain the pixels row by row, starting at the bottom left of the texture. The size of the array must be the width x height of the mipmap level.

SetPixels32 might be slower than some other texture methods because it converts the Color32 struct into the format the texture uses. To set pixel data more quickly, use SetPixelData instead.

You can use SetPixels32 with the following texture formats:

  • Alpha8
  • ARGB32
  • ARGB4444
  • BGRA32
  • R16
  • R16_SIGNED
  • R8
  • R8_SIGNED
  • RFloat
  • RG16
  • RG16_SIGNED
  • RG32
  • RG32_SIGNED
  • RGB24
  • RGB24_SIGNED
  • RGB48
  • RGB48_SIGNED
  • RGB565
  • RGB9e5Float
  • RGBA32
  • RGBA32_SIGNED
  • RGBA4444
  • RGBA64
  • RGBA64_SIGNED
  • RGBAFloat
  • RGBAHalf
  • RGFloat
  • RGHalf
  • RHalf

For all other formats, SetPixels32 fails. Unity throws an exception when SetPixels32 fails.
