IMAQ Get Geometric Features From Curves VI
Owning Palette: Pattern Matching AdvancedInstalled With: NI Vision Development ModuleReturns the geometric features described by a set of curves.
Curves is an array describing the curves found in the image.

||||||||||||||||||||||||||
Feature Types to Extract are the types of features to extract from the passed curves. Pass an empty array to extract all features. The default value is an empty array. |

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Features is a list of geometric features associated with a match.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
