Rotating C# Web Image & Document Page

In order to rotate a current web image or document page, users should first integrate RasterEdge Web Document Viewer Control in your Visual C#.NET web application. Then you can add rotation functioning buttons (bound with corresponding rotation JavaScript APIs) to your viewer by customizing JavaScript code in the Default.aspx. Currently you can use the Visual C# Web Document Viewer to add three types of rotation options to your viewer toolbar.
  • btnRotate90: Rotating the currently viewed page/image clockwise in 90 degrees
  • btnRotate180: Rotating the currently viewed page/image clockwise in 180 degrees
  • btnRotate270: Rotating the currently viewed page/image counterclockwise in 90 degrees

Adding & Deleting Buttons in C# Web Viewer

C#.NET users can easily process your web image or document through adding and deleting a function button in the toolbar of your ASP.NET web document viewer. These can be easily done by editing your C# project web page Default.aspx with a few lines of JavaScript codes. In addition to rotation function button, you may add other control buttons to your web viewer toolbar, like annotation & zoom buttons. If you don't need some of them, you can simply add corresponding JavaScript codes to remove the buttons. A sample code for removing function button is provided below.
//Require amplification function buttons
pageToolbarStr += toolbarZoomIn.CreateHtml();

//Does not need "Processing" Forum
