ImageConversion.EncodeToTGA

Parameters

Description

Encodes the specified texture in TGA format.

For this function to execute properly, Texture.isReadable must be true.

The TGA encoded texture is returned as a byte array. You can store the encoded texture as a file or send it over the network without further processing.

This function works only on uncompressed, non-HDR texture formats.

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.

// Saves screenshot as TGA file.
using UnityEngine;
using System.Collections;

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

    IEnumerator SaveScreenTGA()
    {
        // Read the screen buffer after rendering is complete
        yield return new WaitForEndOfFrame();

        // 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 texture in TGA format
        byte[] bytes = ImageConversion.EncodeToTGA(tex);
        Object.Destroy(tex);

        // Write the returned byte array to a file in the project folder
        File.WriteAllBytes(Application.dataPath + "/../SavedScreen.tga", bytes);
    }
}
