Retrieves the size that the specified view object will be drawn on the specified target device.
HRESULT GetExtent( DWORD dwDrawAspect, LONG lindex, DVTARGETDEVICE *ptd, LPSIZEL lpsizel );
Requested view of the object whose size is of interest. Possible values are taken from the DVASPECT and DVASPECT2 enumerations. Note that newer objects and containers that support optimized drawing interfaces support the DVASPECT2 enumeration values. Older objects and containers that do not support optimized drawing interfaces may not support DVASPECT2.
The portion of the object that is of interest. Currently, the only possible value is -1.
A pointer to the DVTARGETDEVICE structure defining the target device for which the object's size should be returned.
A pointer to where the object's size is returned.
This method returns S_OK on success. Other possible return values include the following.
||An appropriate cache is not available.|
The OLE-provided implementation of IViewObject2::GetExtent searches the cache for the size of the view object.
If one of the new aspects is requested in dwAspect, this method can either fail or return the same rectangle as for the DVASPECT_CONTENT aspect.IOleObject::GetExtent to determine the size of the presentation to be drawn.
