ImageConversion.EncodeArrayToTGA

パラメーター

説明

Encodes this array into 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. 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.

This method is thread safe.

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

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 bytes in TGA format
        byte[] bytes = ImageConversion.EncodeArrayToTGA(tex.GetRawTextureData(), 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);
    }
}
