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:

 

        ZPhotoEngineDll zp = new ZPhotoEngineDll();
        int BLEND_MODE_OVERRLAY = 11;
        public Bitmap LegePixelpuzzleFilter(Bitmap src,Bitmap legemap)
        {
            //马赛克处理,参数20
            Bitmap mosic = zp.MosaicProcess(src,20);
            //色调分离,参数4
            Bitmap porize = zp.Posterize(mosic, 4);
            //图层混合模式-叠加
            Bitmap overlay = zp.ImageBlendEffectProcess(mosic, porize, BLEND_MODE_OVERRLAY);
            mosic.Dispose();
            porize.Dispose();
            Bitmap a = new Bitmap(overlay);
            int w = a.Width;
            int h = a.Height;
            Bitmap map = new Bitmap(legemap);
            BitmapData srcData = a.LockBits(new Rectangle(0, 0, a.Width, a.Height), ImageLockMode.ReadWrite, PixelFormat.Format32bppArgb);

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:

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:点击打开链接
