LVectorRaster::UnlockObject

#include "ltwrappr.h"

virtual L_INT LVectorRaster::UnlockObject(pRaster)

pointer to a vector object

Sets the object information of the class object.

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

Parameter	Description
pRaster	Pointer to a VECTORRASTER structure that contains the vector object information to set.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function is used to update the object information of the class object.

To use this method, declare a variable of type VECTORRASTER and pass the address to the LVectorRaster::LockObject () function. After modifying the vector object settings, call LVectorRaster::UnlockObject (). LVectorRaster::LockObject () and LVectorRaster::UnlockObject () should always be called in pairs.

Before an object has been added to the LVectorBase object, using LVectorBase::AddObject or LVectorLayer::AddObject, LVectorRaster::UnlockObject() can be used to change ALL properties of an object. However, once the object has been added to the LVectorBase object, some properties cannot be changed using LVectorRaster::UnlockObject().

To get the current object information for a class object, call LVectorRaster::LockObject.

LVectorRaster::LockObject and LVectorRaster::UnlockObject must be called in pairs.
