#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecAddLayer(pVector, pLayerDesc, pLayer, dwFlags)

Adds a new empty layer to a vector handle.

This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

pVECTORHANDLE pVector

Pointer to the vector handle.

const pVECTORLAYERDESC pLayerDesc

Pointer to a VECTORLAYERDESC structure that contains the new layer settings.

pVECTORLAYER pLayer

Pointer to a VECTORLAYER structure to be updated with the handle of the new layer.

L_UINT32 dwFlags

Flag that indicates whether or not to rename duplicate layer names. Possible values are:

Returns

Comments

For more information on the layer settings, refer to the VECTORLAYERDESC structure.

To change layer settings, get the current layer settings by calling L_VecGetLayer, set the new settings in the VECTORLAYERDESC structure pointed to by pLayerDesc and then set the new layer settings by calling L_VecSetLayer.
