这篇博客承接上一篇http://blog.csdn.net/trent1985/article/details/50195747乐高像素拼图特效的PS实现，主要是一些博友告诉我如何用代码实现这个PS的特效，为此，这里以这个特效为例，来说一下。

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：

4，有了上述步骤后，我们就完成了一个测试DEMO中，添加ZPhotoEngine.dll的过程，下面我们就可以使用了，其实主要就是两步：添加DLL库+ZPhotoEngineDll.cs。

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：

大家可以看到，就上面这一点代码，就轻松实现了乐高像素拼图特效的滤镜，最后放上效果图对比：

原图

PS实现效果图

程序实现效果图

大家可以对比一下，几乎是一模一样的呵呵，以上就是整个过程了，代码我写的都是主要代码，这里给出整个工程的源代码免费下载地址：

最后在给出ZPhotoEngine库的下载地址：
