# Flaw Detection Vision Data Access functions

Functions that get values from a Surface Flaw data structure.

Note: Each of the following functions references a SurfaceFlaw data structure as the first parameter.

Function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. | Description
GetAngle(Structure, [Index]) | Returns the Angle of the indexed edge.
GetArea(Structure, [Index]) | Returns an area value.
GetAverageIntensity(Structure, [Index]) | Returns the average intensity of the flaw.
GetHeight(Structure, [Index]) | Returns a height value.
GetNFound(Structure) | Returns the total number of flaws found.
GetPerimeter(Structure, [Index]) | Returns a perimeter value.
GetRoundedness(Structure, [Index]) | Returns the roundedness of the flaw.
GetTotalFlawArea(Structure) | Returns the total area of all of the flaws detected by the SurfaceFlaw function.
GetWidth(Structure, [Index]) | Returns a width value.
GetX(Structure, [Index1], [Index2]) | Returns a x-coordinate.
GetY(Structure, [Index1], [Index2]) | Returns a y-coordinate.
