ImageConversion.EncodeArrayToJPG

파라미터

설명

Encodes this array into JPG format.

This function returns a byte array which is the JPG 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 JPG data will be either 8bit grayscale, RGB or RGBA (depending on the passed in format).

This method is thread safe.

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

    IEnumerator SaveScreenJPG()
    {
        // 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 JPG format
        byte[] bytes = ImageConversion.EncodeArrayToJPG(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.jpg", bytes);
    }
