Description
|
---|---|---|
image | Image* | The image that the function uses for intensity measurement. |
start | Point | The coordinate location of the start of the line. |
end | Point | The coordinate location of the end of the line. |
showMeasurement | int | Set this parameter to TRUE to overlay the location of the intensity measurement on the image. Set this parameter to FALSE to leave the image unmodified. |
transform | const CoordinateTransform2* | An optional specification of the coordinate transform for the line. This parameter specifies how to transform the location of the intensity measurement based on the difference between the reference coordinate system and the measurement coordinate system. Set this parameter to NULL if you do not need to transform the line. |
