GM_Layer_tLoadLayer Method

Loads a Data File (deprecated)

Namespace:  GlobalMapper
Assembly:  GlobalMapperWrapperNET (in GlobalMapperWrapperNET.dll) Version: 19.1.0.0 (19.1.0.0)
Syntax
C#
Copy
public static GM_Layer_t LoadLayer(
	string aFilename,
	GM_LoadFlags_t32 aLoadFlags = 
)

Parameters

aFilename
Type: SystemString
The Path to the file to be loaded
aLoadFlags (Optional)
Type: GlobalMapperGM_LoadFlags_t32
Flags for load options

Return Value

Type: GM_Layer_t
The Loaded Layer
Remarks
Loads the given file and returns a layer handle. The layer handle can be used in other calls into the library. The layer must be closed by calling GM_CloseLayer when the caller is done using it.
This function is deprecated. You should use GM_LayerList_t.LoadLayerList as it supports multiple layers being loaded from a single file (this is common with archive files like .zip and .tar.gz as well as multi-map formats like CADRG).
