ITerrainImageLabel81

The Image Label object is a simplified version of the ITerrainLabel81 object. It allows you to create a label that has an image only. For more information about TerraExplorer's labels, see "Text and Image Labels" in the TerraExplorer User Manual.

	Properties
	Action	An IAction81 representing the operation that takes place when the object is clicked in the Project Tree.
	Attachment	An IAttachment81 representing the attachment behavior of the label.
	BlendMode	Determines how the label's image blends with the background terrain or model layer.
	ID	Gets the ID of the label. (Inherited from ITerraExplorerObject81)
	ImageFileName	Gets and sets a full pathname or a URL to the label's image file.
	Message	An IMessageObject81 representing the message object assigned to the object.
	ObjectType	Gets an enum that identifies the type of the object. (Inherited from ITerraExplorerObject81)
	Position	An IPosition81 representing the position and orientation of the label on the terrain.
	SaveInFlyFile	Gets and sets a Boolean that determines whether the label is saved in the Fly file. (Inherited from ITerraExplorerObject81)
	Style	An ILabelStyle81 representing details (e.g. color, size and position) regarding the display of the label in the 3D Window.
	Terrain	An ITerrainObject81 representing terrain properties including draw order and ground object status.
	TimeSpan	An ITimeSpan81 representing the timespan in which the label is visible on the terrain.
	Tooltip	An ITooltip81 representing the tooltip that displays when a mouse cursor is placed over the label in the 3D Window.
	TreeItem	An ITreeItem81 describing the representation of the label in the Project Tree.
	Visibility	An IVisibility81 representing the visibility of the label at different distances.
	Methods
	GetClientData	Gets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject81)
	GetParam	Reserved. Currently not used. (Inherited from ITerraExplorerObject81)
	SetClientData	Sets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject81)
	SetImageFromBuffer	Sets the image label from a memory buffer.
	SetParam	Reserved. Currently not used. (Inherited from ITerraExplorerObject81)

BlendMode

Determines how the label's image blends with the background terrain or model layer:

§ 1 – Adds the image color to the background, e.g., if the terrain is green (RGB: 0, 255, 0), and a red label is drawn on it (RGB: 255, 0, 0), its RGB value is added to the background, to produce a yellow blend (RGB: 255, 255, 0).

§ 0 – Uses normal blending based on the opacity set for the image.
