Description |
|---|---|---|
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipSrcContour |
Single contour (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL; The elements of this container are the points of the contour.) | |
|
ipDestContour |
Returns a container which is filled with the approximated polygon points (same type ID as ipSrcContour; Non-zero interface pointers are reused.) | |
|
fMaxDist |
double |
Maximum distance between the original contour and its approximation |
|
bClosed |
bool |
Specify, if the contour is closed (first and last points connected) or not |
