F_VN_RemapImage

Remap an image with custom maps, i.e. ipDestImage(x,y) = ipSrcImage(mapX(x,y), mapY(x,y)). Supported pairs are (ipMap1 = ET_REAL, 2 channels; ipMap2 = 0), (ipMap1 = ET_REAL, 1 channel; ipMap2 = ET_REAL, 1 channel), (ipMap1 = ET_INT, 2 channels; ipMap2 = ET_UINT, 1 channel), (ipMap1 = ET_INT, 2 channels; ipMap2 = 0).
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

FUNCTION F_VN_RemapImage : HRESULT
VAR_INPUT
    ipSrcImage  : ITcVnImage;
    ipDestImage : Reference To  ITcVnImage;
    ipMap1      : ITcVnImage;

    hrPrev      : HRESULT;
END_VAR

Inputs

Name	Type	Description
ipSrcImage	ITcVnImage	Source image
ipDestImage	Reference To ITcVnImage	Destination image (Must not be the same as ipSrcImage! Has the same size as ipMap1 and the same type as ipSrcImage. An appropriate destination image will be created if required.)
ipMap1	ITcVnImage	Map 1 (ET_REAL with 2 channels (containing mapX, mapY) or ET_REAL with 1 channel (containing mapX) or ET_INT with 2 channels (containing rounded mapX, mapY))
ipMap2	ITcVnImage	Map 2 (ET_REAL with 1 channel (containing mapY) or ET_UINT with 1 channel (containing interpolation table coefficients if ipMap1 is ET_INT with 2 channels), otherwise set to 0 if not required.
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

Return value
