ImageConversion.EncodeToTGA

파라미터

설명

Encodes the specified texture in TGA format.

This function returns a byte array which is the TGA file 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. Texture.isReadable must be true. 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.

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

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 = tex.EncodeToTGA();
        Object.Destroy(tex);

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