Unity实现图片水印生成

本文实例为大家分享了unity实现图片水印生成的具体代码，供大家参考，具体内容如下

用于图片分享时添加logo水印的功能，之前用来做你画我猜的方法，核心是用texture2d中的setpixels方法

具体实现如下

效果图：

上代码，比较简单不多说了

using unityengine;
using system.collections;
using unityengine.ui;
 
public class watermarkadd : monobehaviour {
 public image targetimage;
 public sprite logosprite;
 public sprite imagesprite;
 // use this for initialization
 void start () {
 texture2d t = addlogo(imagesprite.texture, logosprite.texture);
 sprite s = new sprite();
 s=sprite.create(t, new rect(0,0,t.width, t.height),new vector2(0.5f,0.5f));
 targetimage.sprite = s;
 }
 
 private texture2d addlogo(texture2d image,texture2d logo)
 {
 texture2d logotexture = new texture2d(image.width,image.height);
 color[] colors = image.getpixels();
 for (int i = 0; i < logo.width; i++)
 {
  for (int j = 0; j < logo.height; j++)
  {
  color c = logo.getpixel(i, j); 
 
  if (c.a != 0)
  {
   colors[logotexture.width * j + i] = c;
  }
  
  }
 }
 logotexture.setpixels(0, 0, image.width, image.height, colors);
 logotexture.apply();
 return logotexture;
 }
 
 
}
