unity截取图片并合成_unity 拍摄抠图融合

1.首先创建一个UI摄像机，并调整好Layer层，遮罩层之类的，拼拼界面。

2.制作成预制体。（代码中的路径可能需要改）加载的地方改下Resource.Load();

3.先点字一个GUIBUtton，再点第二个才会好使。

下面给出代码自己看看吧，嘿嘿：

using UnityEngine;
using System.Collections;
using System.IO;
 
public class GameUISharePopUp : MonoBehaviour 
{
 
    private string imagePath = "";
	void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 200, 20), "first capture"))
        {
 
            StartCoroutine(GenerateShareScreenshot());
        }
        if (GUI.Button(new Rect(10, 30, 200, 20),"cut"))
        {
            string fileName = Application.persistentDataPath+"wwb";
            Texture2D shareBgImg = LoadImageFromBytes(File.ReadAllBytes(fileName));
            if (shareBgImg == null)
            {
                Debug.LogErrorFormat("Can not load Screenshot Image {0}.", fileName);
                return;
            }
            StartCoroutine(GenerateShareImage("www", "hahaha", shareBgImg));
        }
    }
    private IEnumerator GenerateShareScreenshot()
    {
        string fileName = Application.persistentDataPath + "wwb";
        Debug.Log("fileName= "+fileName);
        if (File.Exists(fileName)) 
            File.Delete(fileName);
        yield
