The Seadragon control can be used for viewing Deep Zoom images. Use your mouse to pan and zoom around the image.

First example above is initialized with this code.

<ajaxToolkit:Seadragon ID="Seadragon"
	runat="server"
	SourceUrl="sample.xml">
	CssClass="seadragon"
</ajaxToolkit:Seadragon>

Second example above is initialized with this code.

<ajaxToolkit:Seadragon ID="Seadragon2"
  runat="server"
  CssClass="seadragon"
  SourceUrl="dzc_output.xml">
  <ControlsCollection>
    <ajaxToolkit:SeadragonControl runat="server"
      Anchor="TOP_RIGHT">
      <asp:Menu runat="server" ...>
        set menu style
        <Items>
          <asp:MenuItem Text="Menu" Value="Menu" />

          <asp:MenuItem Text="Over" Value="Over" />
          <asp:MenuItem Text="Seadragon" Value="Seadragon" />

      Rect-Width="0.26" 
      CssClass="overlay" 
      Rect-Point-X="0.14"

• animationTime - The amount of time in seconds that animations should last. Default is 1.5.
• blendTime - The amount of time in seconds that new tiles take to blend from transparent to opaque. Default is 0.5.
• alwaysBlend - Whether tiles should always blend in and out, not just when they're first loaded. Default is false.
• autoHideControls - Whether controls should get automatically hidden when the user's mouse is off the viewer and the image has stopped animating. Default is true.
• immediateRender - Whether the most appropriate tiles should always be rendered first, before any lower-res tiles are rendered. This loses the "sharpening" effect and instead creates a very visible "tiling" effect. Default is false.
• minZoomDimension - The minimum size (in screen pixels) of either dimension that can result from zooming out. Default is 16.
• maxZoomPixelRatio - The maximum pixel ratio (screen pixel to content pixel) that can result from zooming in. Default is 4.
• visibilityRatio - The minimum portion of the viewport that must show visible content in both dimensions. Default is 0.1.
• springStiffness - Determines how sharply the springs used for animations move. Default is 5.0.
• imageLoaderLimit - The maximum number of concurrent image downloads that can be performed by each viewer. Default is 2.
• clickTimeThreshold - The maximum number of milliseconds that can pass between a mousedown and a mouseup for the action to still be considered a "quick" click. Default is 200.
• clickDistThreshold - The maximum number of pixels the mouse can move between a mousedown and a mouseup for the action to still be considered a "quick" click. Default is 5.
• zoomPerClick - The factor by which images should zoom when clicked on. Default is 2.
• zoomPerSecond - The factor by which images should zoom over each second when the zoom buttons are held down. Default is 2.
• sourceUrl - The path for all UI images. This can be absolute or relative. If relative, it must be relative to the HTML page. A change to this value will only affect new viewers. Default is "img/".
• showNavigationControl - Whether navigation buttons should be shown.
