FloaterImage Property

Summary

Gets or sets the floater image.

Syntax

C++/CLI

C++

public virtual RasterImage FloaterImage { get; set; }

[BrowsableAttribute(false)] 
public: 
virtual property RasterImage^ FloaterImage { 
   RasterImage^ get(); 
   void set (    RasterImage^ ); 
}

public:  
   virtual property RasterImage^ FloaterImage 
   { 
      RasterImage^ get() 
      void set(RasterImage^ value) 
   }

Property Value

A Leadtools.RasterImage object that represents the current floater image.

Remarks

The RasterImageViewer supports a floater image that can be dragged with the mouse when the value of the InteractiveMode is set to RasterViewerInteractiveMode.Floater

If the value of the floater image has a region, then only the region will be painted. This region can be animated by setting the value of the AnimateFloater property to true.

The position of the floater can be manipulated with the FloaterPosition property.

You can use the FloaterVisible property to control whether to view the floater.

Example

This sample lets you create a floater, move the floater, and combine the floater with the image.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Drawing; 
 
private void viewer_FloaterInteractiveModeEnded(object sender, EventArgs e) 
{ 
   // an interactive mode is done.  check if its drawing a region 
   // if so, convert the region to a floater and set the interactive 
   // mode so that we can drag the floater 
   RasterImageViewer viewer = sender as RasterImageViewer; 
   if (viewer.InteractiveMode == RasterViewerInteractiveMode.Region) 
   { 
      viewer.EnableTimer = true; 
      viewer.RegionToFloater(); 
      viewer.FloaterVisible = true; 
      viewer.AnimateFloater = true; 
      viewer.InteractiveMode = RasterViewerInteractiveMode.Floater; 
 
      // delete the region since we do not need it anymore 
      viewer.Image.MakeRegionEmpty(); 
 
      MessageBox.Show("Move the floater around, double click anywhere on the viewer to combine it with the image"); 
   } 
} 
 
private void viewer_DoubleClick(object sender, EventArgs e) 
{ 
   // check if the interactive mode is Floater, if so,  
   // combine the floater with the image. 
   RasterImageViewer viewer = sender as RasterImageViewer; 
   if (viewer.InteractiveMode == RasterViewerInteractiveMode.Floater) 
   { 
      viewer.InteractiveMode = RasterViewerInteractiveMode.None; 
      viewer.CombineFloater(true, ImageProcessing.CombineFastCommandFlags.SourceCopy); 
 
      // get rid of the floater since we do not need it anymore 
      viewer.FloaterImage = null; 
      MessageBox.Show("The floater has been combined with the image"); 
   } 
} 
 
public void RasterImageViewer_FloaterImage(RasterImageViewer viewer) 
{ 
   // hook into the viewer InteractiveModeEnded and DoubleClick events 
   viewer.InteractiveModeEnded += new EventHandler(viewer_FloaterInteractiveModeEnded); 
   viewer.DoubleClick += new EventHandler(viewer_DoubleClick); 
 
   // first set the interactive mode to draw a freehand region 
   viewer.InteractiveRegionType = RasterViewerInteractiveRegionType.Freehand; 
   viewer.InteractiveRegionCombineMode = RasterRegionCombineMode.Set; 
   viewer.InteractiveMode = RasterViewerInteractiveMode.Region; 
 
   MessageBox.Show("Draw a freehand region on the image"); 
 
}
