CheckIfPointIsInsideContour
Checks if a point is inside a contour (and optionally return the distance to it).

HRESULT CheckIfPointIsInsideContour(

TcVnPoint2_REAL& aPoint,
double& fDist,
bool bMeasureDistance

Description |
|---|---|---|
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipContour |
Single contour (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL) | |
|
aPoint |
Point position to check | |
|
fDist |
double& |
Returns the result (> 0: the point is inside the contour; 0: the point is on the contour; < 0: the point is outside the contour) |
|
bMeasureDistance |
bool |
If true, fDist returns the distance to the nearest contour edge. Otherwise, fDist only returns -1, 0 or +1 (recommended to set to false if the distance is not required, as this is faster). |
