L_LTVKRN_API L_INT L_VecSetActiveLayer(pVector, pLayer)
Sets the active layer in the specified vector handle. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Pointer to the vector handle.
Pointer to the VECTORLAYER structure that references the layer to set as the active layer.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
Some functions use the active layer when NULL is passed for a pVECTORLAYER parameter. This makes it easier to work with the toolkit when layers are not needed.
Required DLLs and Libraries
This example will set the active layer to the one with the given name.
