Description |
|---|---|---|---|
|
hrPrev |
|
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipContours |
|
Single contour (ContainerType_Vector_TcVnPoint2_DINT) or multiple contours (ContainerType_Vector_Vector_TcVnPoint2_DINT) | |
|
nContourIndex |
LONG |
|
Index of a specific contour to be drawn (if negative, all contours within the container are drawn) |
|
ipDestImage |
|
Destination image | |
|
aColor |
|
Color | |
|
nThickness |
LONG |
|
Line thickness (if negative, the contours are filled) |
|
eLineType |
LT_8_CONNECTED |
Line type | |
|
ipHierarchy |
nullptr |
Contour hierarchy (ContainerType_Vector_TcVnVector4_DINT) | |
|
nMaxLevel |
LONG |
2147483647 |
Maximum level of contours to be drawn |
|
aOffset |
{0, 0} |
Offset by which every contour point is shifted |
