Description |
|---|---|---|
|
ipSrcImage |
Source image (1-4 channels of 8 or 16 bit types SINT, USINT, INT, UINT) | |
|
ipDestImage |
Reference To ITcVnImage |
Returns the result image (same size, type and channels as ipSrcImage. An appropriate image will be created if required.) |
|
ipLut |
Lookup table with elements matching ipSrcImage type and either 256 (8 bit images) or 65536 (16 bit images) elements. E.g. ContainerType_Vector_USINT for 1-4 channel USINT image (in this case, the same lookup values are used for each channel) or ContainerType_Vector_TcVnVector3_USINT for a 3 channel USINT image (in this case, each channel uses an individual lookup value). | |
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
