| input | The native array to convert. |
| format | The pixel format of the image data. |
| width | The width of the image data in pixels. |
| height | The height of the image data in pixels. |
| rowBytes | The length of a single row in bytes. The default is 0, which means Unity calculates the length automatically. |
Encodes this native array into TGA format.
This function returns a NativeArray<byte> which is the TGA data. Write this data to disk to get the data in the TGA file format.
The encoded TGA data is not compressed and contains an alpha channel for RGBA32, ARGB32 textures, and no alpha channel for RGB24 textures. For single-channel red textures ( R8, R16, RFloat and RHalf ), the encoded TGA data will be in 8-bit grayscale.
This method is thread safe.

// Read the screen contents into the texture tex.ReadPixels(new Rect(0, 0, width, height), 0, 0); tex.Apply();
// Encode the bytes in TGA format NativeArray<byte> imageBytes = new NativeArray<byte>(tex.GetRawTextureData(), Allocator.Temp); var bytes = ImageConversion.EncodeNativeArrayToTGA(imageBytes, tex.graphicsFormat, (uint)width, (uint)height); Object.Destroy(tex);
// Write the returned byte array to a file in the project folder File.WriteAllBytes(Application.dataPath + "/../SavedScreen.tga", bytes.ToArray()); } }
