L_VecAddObject

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecAddObject(pVector, pLayer, nType, pObjectDesc, pNewObject)

Adds a new object to a vector layer. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

pVECTORHANDLE pVector

Pointer to the destination vector handle.

const pVECTORLAYER pLayer

Pointer to the destination vector layer.

L_INT nType

Type of object to add. Possible values are:

const L_VOID * pObjectDesc

Pointer to a vector object that contains information about the object to add.

pVECTOROBJECT pNewObject

Pointer to a VECTOROBJECT structure that references the newly added object.

Returns

Comments

If pLayer is NULL, the object will be added to the current active layer within the vector handle.

If pNewObject is NULL, this pointer will not be updated with the address of the newly added object.

You may need to cast from your given object type (VECTORPOLYGON, VECTORTEXT, etc) when using this function. (See the example below.)
