Converts an ROI descriptor to a line.
Descriptor that defines the line.
Minimum rectangle required to contain all of the contours in the ROI.
Individual shapes that define an ROI.
Object specifying if contour is the external or internal edge of an ROI.
Shape type of the contour.
Relative position of the 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.
Default: No error
Coordinates of the line.
X-coordinate of the beginning point of the line.
Y-coordinate of the beginning point of the line.
X-coordinate of the end point of the line.
Y-coordinate of the end point of the line.
Error information.
