2. 소스

2.1 화면 캡처 후 jpg 파일로 저장

IEnumerator SaveScreeJpg(string filePath)
{
    yield return new WaitForEndOfFrame();

    Texture2D texture = new Texture2D(Screen.width, Screen.height);
    texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
    texture.Apply();
    byte[] bytes = texture.EncodeToJPG();
    File.WriteAllBytes(filePath, bytes);
    DestroyImmediate(texture);
}

 

2.2 화면 캡처 후 tga 파일로 저장

IEnumerator SaveScreenTga(string filePath)
{
    yield return new WaitForEndOfFrame();

    Texture2D texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
    texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
    texture.Apply();
    byte[] bytes = texture.EncodeToTGA();
    File.WriteAllBytes(filePath, bytes);
    DestroyImmediate(texture);
}

 

2.3 화면 캡처 후 exr 파일로 저장

IEnumerator SaveScreeExr(string filePath)
{
    yield return new WaitForEndOfFrame();

    Texture2D texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGBAFloat, false);
    texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
    texture.Apply();
    byte[] bytes = texture.EncodeToEXR(Texture2D.EXRFlags.CompressZIP);
    File.WriteAllBytes(filePath, bytes);
    DestroyImmediate(texture);
}
