ControlInertiaScrollOptions Structure

Summary

Options to use with inertia scroll support.

Syntax

C++/CLI

public struct ControlInertiaScrollOptions

public value class ControlInertiaScrollOptions sealed

Remarks

To enable inertia scroll, get the options from the property, set the value of IsEnabled to true, and then set the value back into the property.

ImageViewerPanZoomInteractiveMode supports inertia scrolling when panning the image.

Use CalculateInertia to pass a custom decleration function of type CalculateInertiaCallback for inertia scrolling, or DefaultBezierPoint1, DefaultBezierPoint2, DefaultDuration, and DefaultPower to change the deceleration of the default inertia function DefaultCalculateInertia.

See CreateDefault for the default values of this object.

Example

using Leadtools; 
using Leadtools.Controls; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
 
 
public ImageViewer _imageViewer; 
 
public void ImageViewerExample() 
{ 
   // Create the image viewer 
   _imageViewer = new ImageViewer(); 
   _imageViewer.Dock = DockStyle.Fill; 
   _imageViewer.BackColor = SystemColors.AppWorkspace; 
   this.Controls.Add(_imageViewer); 
   _imageViewer.BringToFront(); 
 
   // Add Pan/Zoom interactive mode 
   // Click and drag to pan, CTRL-Click and drag to zoom in and out 
   _imageViewer.DefaultInteractiveMode = new ImageViewerPanZoomInteractiveMode(); 
 
   // Get each ImageViewerInteractiveMode. This should only return PanZoom 
   foreach (var mode in _imageViewer.InteractiveModes) 
   { 
      Debug.WriteLine(mode); 
   } 
 
   var intertiaOptions = ControlInertiaScrollOptions.CreateDefault(); 
   intertiaOptions.IsEnabled = true; 
 
   // Load an image 
   using (var codecs = new RasterCodecs()) 
      _imageViewer.Image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "image1.cmp")); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
