ImageConversion.EncodeArrayToTGA

파라미터

설명

Encodes this array into TGA format.

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.

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.

Passing rowBytes of 0 will calculate the row length in bytes automatically.

    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);
    }
