L_VecGetObjectRect

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecGetObjectRect(pVector, pObject, pRect, dwFlags)

Gets the physical bounding rectangle for the specified object(s).

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

const pVECTOROBJECT pObject

Pointer to a VECTOROBJECT structure that references an object. If this parameter is not NULL, the bounding rectangle of this object will be copied into pRect.

If this parameter is NULL, dwFlags will control which objects rectangle to copy into pRect.

L_RECT *pRect

Pointer to a RECT structure to be updated with the bounding rectangle of the specified object(s).

L_UINT32 dwFlags

Flag that indicates which parallelogram to use when updating the pLeftTop and pRightBottom parameters. This flag is valid only if pObject is NULL. If pObject is not NULL, this parameter is ignored. Possible values are:

Returns

Comments

Obtains the physical bounding rectangle of a single object, all selected objects, or all objects within the specified vector handle.
