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

The returned byte array is the JPG "file". You can write them to disk to get the JPG file, send them over the network, etc.

This function works only on uncompressed, non-HDR texture formats. You must enable the texture's Read/Write Enabled flag in the Texture Import Settings. The encoded JPG data will have no alpha channel, and for single-channel red textures ( R8, R16, RFloat and RHalf ) the encoded JPG data will be in 8-bit grayscale.

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

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);
    }
}
