Description |
---|---|---|
ipSrcImage |
Source image (USINT, 1 channel) | |
ipDestImage |
Reference To ITcVnImage |
Destination image (USINT, 1 channel. x: position, y: intensity, origin: bottom left. An appropriate destination image will be created if required.) |
nScaleX |
DINT |
Scale in x direction (ipDestImage will have a width of nScaleX * (ipSrcImage width - 1) + 1) |
nScaleY |
DINT |

nThickness |
DINT |
Line thickness |
nDestChannels |
DINT |
ipDestImage channels (1 or 3) |
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
