LBitmapWindow::GetRgnCurveOptions
#include "ltwrappr.h"
virtual L_VOID LBitmapWindow::GetRgnCurveOptions(puFillMode, pdTension = NULL, pnClose = NULL)
| L_UINT * puFillMode; | /* pointer to a variable to be updated */ | 
| L_DOUBLE * pdTension; | /* pointer to a variable to be updated */ | 
| L_INT * pnClose; | /* pointer to a variable to be updated */ | 
Gets the curved region’s options set for the class object.
| Parameter | Description | |
| puFillMode | Pointer to a variable to be updated with the filling mode. Possible values are: | |
| 
 | Value | Meaning | 
| 
 | L_POLY_WINDING | [0] All pixels that are inside the resulting exterior lines are in the region. | 
| 
 | L_POLY_ALTERNATE | [1] The region includes the area between odd-numbered and even-numbered polygon sides on each scan line. | 
| pdTension | Pointer to a variable to be updated with the tension value. Possible values range from 0.0 to 1.0. NULL is the default value. | |
| pnClose | Pointer to a variable to be updated with a value that specifies how the curve is closed. Possible values are: | |
| 
 | Value | Meaning | 
| 
 | CURVE_NO_CLOSE | [0x0] For n points, draw (n – 3) segments. For example, for points {P0, P1, P2, P3, P4}, draw segments P1P2 and P2P3. | 
| 
 
 | CURVE_CLOSE | [0x1] For n points draw (n) segments. For example, for points {P0, P1, P2, P3, P4}, draw segments P0P1, P1P2, P2P3, P3P4, P4P0. | 
| 
 
 | CURVE_PARTIAL_CLOSE | [0x2] For n points draw (n – 1) segments. For example, for points {P0, P1, P2, P3, P4}, draw segments P0P1, P1P2, P2P3, P3P4 (but not P4P0). | 
| 
 | NULL is the default value. | |
Returns
None.
