GetBoundingBox()

This method gets a bounding box of the Overlay.

This method is the concrete wrapper for the abstract method GetBoundingBoxCore. This method returns the bounding box of the Overlay. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

• Type:RectangleShape
• Description:A RectangleShape indicating the bounding box of this overlay.

Initialize(MapArguments)

This method initializes overlay object.

This is a wrapper method for the virtual method InitializeCore.

• Type:Void
• Description:N/A

• mapArguments
  • Type:MapArguments
  • Description:This parameter maintains current map information for calculating mechanism.

Refresh()

This method refreshes all the content in the OverlayCanvas. For example, LayerOverlay with multiple tiles; when the style of one layer is changed, call Refresh to refresh all the tiles to accept new styles.

The difference from Draw() method is that Refresh() method refreshs all the elements while Draw() does not.

• Type:Void
• Description:N/A

Draw(MapArguments,OverlayRefreshType)

This method draws the overlay with the provided extent in world coordinate.

N/A

• Type:Void
• Description:N/A

• mapArguments
  • Type:MapArguments
  • Description:This parameter maintains current map information for calculating mechanism.

• refreshType
  • Type:OverlayRefreshType
  • Description:This parameter indicates whether the elements of this overlay needs to be refreshed. For example, TileOverlay is formed by tiles. When panning the map around, the existing tile doesn't need to be redraw, the only thing we need to do is modifying the position of these tiles. On another hand, when click to change the style of the overlay, we need to redraw the tile images to change the appearance. So we need refresh mode.

PostTransform(TransformArguments,MapArguments)

This method will simulate the PostTransform interaction.

N/A

• Type:Void
• Description:N/A

• transformInfo
  • Type:TransformArguments
  • Description:This parameter maintains the transfrom information for calculating transform.

• mapArguments

This method draws the overlay with the provided extent in world coordinate.

N/A

• Type:Void
• Description:N/A

• mapArguments
  • Type:MapArguments
  • Description:This parameter maintains current map information for calculating mechanism.

• refreshType
