图像滤镜艺术—乐高像素拼图特效滤镜的代码实现

这个特效的实现我们将使用ZPhotoEngine库来完成，采用C#编程，步骤如下：

1，打开VS构建工程TestDemo，添加一些基本功能：打开图像，保存图像，这个代码我会给出连接，这个不是重点，大家接着往下看。

2，在工程中导入ZPhotoEngine的dll，放在bin/debug，bin/Release文件夹中，主要包含这几个：pthreadVC2.dll、ZPhotoEngine.dll，ZEffectEngine.dll不添加也没关系，这个特效中没有使用到这个滤镜模块库。

3，根据ZPhotoEngine库的说明文档，或者ZPhotoEngine.h的接口说明，对接口进行封装。

实际上ZPhotoEngine库的DEMO中已经有了大部分的封装，都在ZPhotoEngineDll.cs中，这里只缺少了图层混合模式的接口封装，我们封装之后，所有代码如下，大家只需要把这个文件添加到你的工程中即可：

5，下面我们按照上一篇博文中PS的实现步骤，写出代码如下：

别想一下造出大海，必须先由小河川开始。
