Example

This example will add a few items to the ImageViewer and then create a new interactive mode that transform the item using mouse or touch.

Run the demo. Click on any item and drag to translate, CTRL-click to zoom the item in and out.

Start with the ImageViewer example, remove all the code inside the example function (search for the "// TODO: add example code here" comment) and insert the following code:

C#
using Leadtools; 
using Leadtools.Controls; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ImageViewerTranslateItemScaleFactor_Example(int dx, int dy) 
{ 
   if (dx == 0 && dy == 0) 
      return; 
 
   _imageViewer.TranslateItemScaleFactor(_imageViewer.ActiveItem, -dx, -dy, true); 
}
