public static NativeArray<byte> EncodeNativeArrayToTGA(NativeArray<T> input, Experimental.Rendering.GraphicsFormat format, uint width, uint height, uint rowBytes);


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. You can store the encoded data as a file or send it over the network without further processing.

This function does not work on any compressed format. The encoded TGA data will be uncompressed 8bit grayscale, RGB or RGBA (depending on the passed in format). For single-channel red textures ( R8, R16, RFloat and RHalf ), the encoded TGA data will be in 8-bit grayscale.

The native array that this function returns is allocated with the persistent allocator, so this function should only be called from the main thread.

public class TGAScreenSaver : MonoBehaviour { // Take a shot immediately IEnumerator Start() { yield return SaveScreenTGA(); }

// Create a texture in RGB24 format the size of the screen int width = Screen.width; int height = Screen.height; Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);

// 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()); } }
