Loads an imagery layer into the project. Adding the image uses a set of plugins that support multiple file formats. The coordinates of the source can be passed via the UpperLeftX/Y and LowerRightX/Y parameters. If all four coordinate field values are zero, the coordinate information, if available, is read from the file. If the source file coordinate system is not the same as the MPT file Terrain Coordinate system, you can reproject it using ITerrainRasterLayer66. CoordinateSystem.

Parameters
ImageryFileName
A full path name to the image to import to the terrain.
UpperLeftX
The West-East coordinate of the imagery layer’s upper left corner in the project’s coordinate system units. If all four coordinate field values are zero, the coordinate information, if available, is read from the file.
UpperLeftY
The North-South coordinate of the imagery layer’s upper left corner in the project’s coordinate system units. If all four coordinate field values are zero, the coordinate information, if available, is read from the file.
LowerRightX
The West-East coordinate of the imagery layer’s lower right corner in the project’s coordinate system units. If all four coordinate field values are zero, the coordinate information, if available, is read from the file.
LowerRightY
The North-South coordinate of the imagery layer’s lower right corner in the project’s coordinate system units. If all four coordinate field values are zero, the coordinate information, if available, is read from the file.
InitParam
Reserved. Always pass null for this parameter.
PlugName
The name of the plugin used to read the file, e.g., “tifplg.rct“. The available plugins are files with RCT extension that exist in the “TBPlugs directory. If an empty string is passed into this parameter, the default plugin for the file type is used.
GroupID
The Project Tree group in which the imagery layer is created. If it is set to an empty string, the object is created under the root. You can obtain the GroupID by one of the following methods:
· Create the group using IProjectTree66.CreateGroup.
· Find the group, if you know the name, using IProjectTree66.FindItem.
· Traverse the Tree using IProjectTree66 methods such as GetNextItem, until you come to the desired GroupID.
Description
The name of the imagery layer as it appears in the Project Tree. If an empty string is passed into this parameter, TerraExplorer assigns it a unique name.
Return Value
pITerrainRasterLayer66
An ITerrainRasterLayer66, representing the newly created imagery layer.
Exceptions
See: HRESULT Return Values for a list of possible values returned by the HRESULT.
