L_LVKRN_API L_INT L_VecSetLocked(pVector, bLock)
Locks or unlocks the specified vector handle. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Pointer to a vector handle.
Flag that indicates whether to lock or unlock the specified vector handle. Possible values are:
Value | Meaning |
---|---|
TRUE | Lock the specified vector handle. |
FALSE | Unlock the specified vector handle. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
Locking a vector handle has precedence over locking layers within the vector handle. Therefore, if a vector handle is locked, the layers within that vector handle cannot be edited, even if the layers are not locked.
To lock a layer, set the bLocked member of a VECTORLAYERDESC structure to TRUE and update the layer information using the L_VecSetLayer function.
Required DLLs and Libraries
This example will toggle the lock property of a vector handle.
