virtual L_UINT LAnnAutomation::GetPolyFillMode()
Determines how a Polygon annotation with crossing lines is filled.
The polygonal fill-mode constant. Possible 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. |
Win32, x64.
This example gets and updates the property of the object
passed by the caller
L_INT LAnnAutomation_GetPolyFillModeExample(LAnnAutomation * pAnnObject)

if (PolyFillMode == ANNPOLYFILL_WINDING)
