ImageConversion.EncodeToJPG

パラメーター

説明

テクスチャを JPG 形式にエンコードします

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. Texture.isReadable must be true. The encoded JPG data will be either 8bit grayscale, RGB or RGBA (depending on the passed in format).

// Saves screenshot as JPG file.
using UnityEngine;
using System.Collections;

public class JPGScreenSaver : MonoBehaviour
{
    // Take a shot immediately
    IEnumerator Start()
    {
        yield return SaveScreenJPG();
    }

    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 texture in JPG format
        byte[] bytes = tex.EncodeToJPG();
        Object.Destroy(tex);

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