樂高像素拼圖特效濾鏡的代碼實現 · 圖像濾鏡藝術

這篇博客承接上一篇http://blog.csdn.net/trent1985/article/details/50195747樂高像素拼圖特效的PS實現，主要是一些博友告訴我如何用代碼實現這個PS的特效，為此，這里以這個特效為例，來說一下。這個特效的實現我們將使用ZPhotoEngine庫來完成，采用C#編程，步驟如下： 1，打開VS構建工程TestDemo，添加一些基本功能：打開圖像，保存圖像，這個代碼我會給出連接，這個不是重點，大家接著往下看。 2，在工程中導入ZPhotoEngine的dll，放在bin/debug，bin/Release文件夾中，主要包含這幾個：pthreadVC2.dll、ZPhotoEngine.dll，ZEffectEngine.dll不添加也沒關系，這個特效中沒有使用到這個濾鏡模塊庫。 3，根據ZPhotoEngine庫的說明文檔，或者ZPhotoEngine.h的接口說明，對接口進行封裝。實際上ZPhotoEngine庫的DEMO中已經有了大部分的封裝，都在ZPhotoEngineDll.cs中，這里只缺少了圖層混合模式的接口封裝，我們封裝之后，所有代碼如下，大家只需要把這個文件添加到你的工程中即可： ~~~ using System;
