# InspectEdge Vision Data Access functions

This topic lists the Vision Data Access functions that get values from an InspectEdge structure. Each of the following functions references a data structure for the first parameter. Index (zero-based) determines which is being indexed from the structure.

Note: All of the formulas for the InspectEdge functions conform to the following:

- InspectEdgeForDefect/ Position/ Width = An Inspect data structure output by the specified function
- Caliper Index = 0 to N (the total number of Calipers is equal to the number of Calipers output by the InspectEdge function that the InspectEdgeForDefect/ Position/ Width function is referencing)
- Edge Pair Index = 0 or 1 (determines which line fit to reference; 0 = the first line fit, and 1 = the second line fit)
- Edge Index = 0 to N
- Point Index = 0 to 1
