WidenPath
The WidenPath function redefines the current path as the area that would be painted if the
path were stroked using the pen currently selected into the given device
context.
BOOL WidenPath(
HDC hdc
| // handle of device context
| );
|
|
Parameters
hdc
Identifies a device context that contains a closed path.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError. GetLastError may return one of the following error codes:
ERROR_CAN_NOT_COMPLETE
ERROR_INVALID_PARAMETER
ERROR_NOT_ENOUGH_MEMORY
Remarks
The WidenPath function is successful only if the current pen is a geometric pen created by
the ExtCreatePen function, or if the pen is created with the CreatePen function and has a width, in device units, of more than one.
The device context identified by the hdc parameter must contain a closed path.
Any Bézier curves in the path are converted to sequences of straight lines
approximating the widened curves. As such, no Bézier curves remain in the path
after WidenPath is called.
