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.
