imageViewer1同时显示两个以上图片

gw0506

如题：
在imageViewer1中同一平面同时显示两个以上图片(就像ps中的图像拼接），有没有这方面例子或者方法。谢谢

我已经找到一点门路了，好像得设置 FloaterImage 但是我没有找到具体的例子，求助啊

本身imageViewer只能加载一个ImageSource。我大概理解你需要的功能，不过imageviewer不支持。

不过根据这个需求，我个人建议可以考虑在Form里放多个imageviewer，然后自己接事件做imageviewer的拖动等行为。不过这个想法就没有示例可参考了。

你好我说的这个功能leadtools是肯定能实现，或许我表达的方法不对，因为我在之前的公司就用过，他们用的就是leadtools的开发的，而且之前工程师也说是用leadtools实现的，但具体怎么实现的不方便说。

假如你这里查不到的话，哪我想问下 CombineFloater Method (ImageViewer) 这个浮图类似的功能，或者例子有没有呢，我没有找到。

太太好了，如果你愿意把你实现的方法的例子分享出来，发布到“源码库”中，让更多人收益，我们可以送你金币表示感谢～～

大概思路如下：

   public void Addimg(RasterImage img)
      {
         //从外部添加图像，第2次自动浮图
         if (_img == null)
         {
            _img= img.Clone();
            imgeview.Image = CreateA0Image(_img).Clone();
            imgeview.Floater = _img.Clone();
            imgeview.CombineFloater(true);

         }
         else
         {
            imgeview.Floater = img.Clone();
         }
      }

      public RasterImage CreaimgeA0(RasterImage img)
      {

         //创建拼接图像的约4倍
         RasterImage result;
         try
         {
            float num = (float)(400 * img.XResolution) / 25.4f;
            float num2 = (float)(850 * img.YResolution) / 25.4f;
            RasterImage rimage = new RasterImage(RasterMemoryFlags.Conventional, (int)num, (int)num2, img.BitsPerPixel, img.Order, img.ViewPerspective,

img.GetPalette(), IntPtr.Zero, 0);

            FillCommand cmdfill = new FillCommand(RasterColor.White);
            cmdfill.Run(rimage);
            rimage.XResolution = img.XResolution;
            rimage.YResolution = img.YResolution;
            result = rimage;
         }
         catch
         {
            result = null;
         }
         return result;
      }

      public static Frmpj CreateFrom()
      {
         //一个窗体
         if (instance == null || instance.IsDisposed)
         {
            instance = new Frmpj();
         }
         return instance;
      }



      private void button5_Click(object sender, EventArgs e)
      {

         //移动浮图

         imgeview.InteractiveModes.BeginUpdate();
         imgeview.InteractiveModes.Add(new ImageViewerFloaterInteractiveMode
         {
            ZoomKeyModifier = Keys.None,
            IsEnabled = true,
            FloaterOpacity = 0.5
         });
         imgeview.InteractiveModes.EndUpdate();
      }
