RawTextureData Processing Examples
Documentation gives little helpful information on this topic so I created this repo to document how to create matching data structure + how to read & process it in a IJobParallelFor.
This repository contains these kinds of processing examples:
- Invert color
- Edge detection
- Box Blur
- Gaussian Blur
- Grayscale
Tester window available under MenuItem "Test/Raw Texture Data/Processing Example"
Note GetRawTextureData<T> will return all the raw texture data including data from the mipmaps should they be enabled. In such case the length of the array will be longer than width * height.
GetPixelData<T> does not suffer from this issue as you can pass in the desired mip level (usually 0).
Quick lookup table
Valid <T> for GetRawTextureData<T> & GetPixelData<T> or depending on texture.format property:
TextureFormat.Alpha8-<byte>TextureFormat.R8-<byte>TextureFormat.R16-<ushort>,<byte2>TextureFormat.RG32-<ushort2>TextureFormat.RGB48-<ushort3>TextureFormat.RGBA64-<ushort4>TextureFormat.RHalf-<half>,<byte2>TextureFormat.RFloat-<float>,<byte4>TextureFormat.RGB24-<byte3>TextureFormat.RGBA32-<Color32>,<byte4>TextureFormat.RGBAHalf-<half4>,<byte2x4>TextureFormat.RGBAFloat-<Color>,<Vector4>,<float4>,<byte4x4>
