datatype_icon

contour image in

Reference to the image containing a contour.

datatype_icon

pixel radius

Neighborhood pixel relationship for the initial subset of points being used.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

contour image out

Reference to the image containing a contour.

datatype_icon

line

Intersection of the line equation and the contour.

datatype_icon

Point1 (Pixels)

Start point of the calculated fit line in pixel units.

datatype_icon

x

X-coordinate of the point.

datatype_icon

y

Y-coordinate of the point.

datatype_icon

Point2 (Pixels)

End point of the calculated fit line in pixel units.

datatype_icon

x

X-coordinate of the point.

datatype_icon

y

Y-coordinate of the point.

datatype_icon

line equation

Cluster of three coefficients A, B, and C of the equation in the normal form (Ax + By + C=0) of the best fit line.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
