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>

Bestiary:

• public struct byte2 { public byte x, y; }
• public struct byte3 { public byte x, y, z; }
• public struct byte4 { public byte x, y, z, w; }
• public struct byte2x4 { public byte2 c0, c1, c2, c3; }
• public struct byte4x4 { public byte4 c0, c1, c2, c3; }
• public struct ushort2 { public ushort x, y; }
• public struct ushort3 { public ushort x, y, z; }
• public struct ushort4 { public ushort x, y, z, w; }
