Get Contour Information (G Dataflow)

Reference to the image containing a contour.

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

Boolean that specifies if the contour has a fitted equation.

Reference to the image containing a contour.

Location of every point detected on the curve, in pixels.

x

X-coordinate of the point.

y

Y-coordinate of the point.

Curvature profile for the selected contour, in pixels.

Length, in pixels, of the curves in the image.

Error information.

The node produces this output according to standard error behavior.

Location of every point detected on the curve, in calibrated units.

Curvature profile for the selected contour, in calibrated units.

Length, in calibrated units, of the curves within the curvature range.
