virtual L_INT LAnnAutomation::SetPolyFillMode(uPolyFillMode=ANNPOLYFILL_WINDING, uFlags=0)
Sets the value that determines how a polygonal annotation with crossing lines is filled.
The constant that specifies the polygon fill mode. Possible polygon fill mode values are:
Value | Meaning |
---|---|
ANNPOLYFILL_WINDING | [0] All pixels that are inside the resulting exterior lines are filled. |
ANNPOLYFILL_ALTERNATE | [1] The filled area includes the area between odd-numbered and even-numbered polygon sides on each scan line. |
Reserved for future versions, use 0.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function affects only Polygon objects. For descriptions of the various types of objects and their properties, refer to Types of Annotations.
Win32, x64.
