arcgis开发笔记【打印】

Web打印

从网上找了一些关于asp.net打印的资料，参考“关于Web打印”，参考

http://cid-56b433ad3d1871e3.skydrive.live.com/self.aspx/.Public/%e5%85%b3%e4%ba%8eWEB%e6%89%93%e5%8d%b0.docx

最后选择了使用ReportViewer实现打印功能

arcgis silverlight内容的打印

实现思路：

silveilight程序中把页面中需要打印的对象转换成图形base64编码的字符流，提交到服务端

服务端处理程序把这些二进制字符流邦定到ReportViewer控件上，然后由ReportViewer实现打印的展现功能，具体如下：

HOST silverlight的页面

 
SilverLight提交打印请求 
private void Button_Click(object sender, RoutedEventArgs e)    
{        
  WriteableBitmap bitmap = new WriteableBitmap(this.gridTest, new TranslateTransform());             EditableImage image = new EditableImage(bitmap.PixelWidth, bitmap.PixelHeight);       
 for (int i = 0; i < bitmap.PixelHeight; i++)       
 {           
 for (int j = 0; j < bitmap.PixelWidth; j++)            
{              
  int num3 = bitmap.Pixels[(bitmap.PixelWidth * i) + j];           
     image.SetPixel(j, i, (byte) ((num3 >> 0x10) & 0xff), (byte) ((num3 >> 8) & 0xff), (byte) (num3 & 0xff), (byte) ((num3 >> 0x18) & 0xff));           
 }     
   }    
    Stream stream = image.GetStream();      
  byte[] buffer = new byte[stream.Length];  
      long num4 = stream.Read(buffer, 0, (int) stream.Length);    
    string str = Convert.ToBase64String(buffer, 0, buffer.Length);        HtmlPage.Document.GetElementById("prText").SetProperty("value", str);        HtmlPage.Document.GetElementById("prBtn").Invoke("click", null);  
  }
