Structures Vision Data Access Functions
This topic lists the Vision Data Access Functions that get values from data structures as input.
Function | Description |
---|---|
GetAngle(Structure, [Index]) |
Returns the Angle value from the indexed Cross, Fixture or Region data structure. |
GetCount(Structure) |
Returns the Count value from the specified structure. |
GetCurve(Structure, [Index]) |
Returns an angle-of-curvature value in clockwise degrees from the indexed Region structure. |
GetHeight(Structure, [Index]) |
Returns the height value from the indexed Cross or Region structure. |
GetNPoints(Structure, [Index]) |
Returns the number of points of a structure. |
GetNSubregions(CompositeRegion, [Index]) |
Returns the number of subregions of a composite region. |
GetOperation(CompositeRegion, [Index]) |
Returns the operation of the specified subregion of a composite region. |
GetRadius(Structure, Index) |
Returns the Radius value from the indexed Annulus or Circle structure. |
GetSegmentArea(Mask, Index) |
Returns the area of the indexed segment from a Mask structure, or segment 0 if no index is specified. |
GetSegmentX(Mask, Index) |
Returns the X coordinate of the indexed segment from a Mask structure, or segment 0 if no index is specified. |
GetSegmentY(Mask, Index) |
Returns the Y coordinate of the indexed segment from a Mask structure, or segment 0 if no index is specified. |
GetSubregionType(CompositeRegion, Index) |
Returns the shape type of the specified subregion. |
GetWidth(Structure) |
Returns the width value from the indexed Cross or Region structure. |
GetX(Structure, [Index1], [Index2]) |
Returns an x-coordinate from the indexed Annulus, Circle, Cross, Fixture, Fixtures, Line, Point or Region structure. Note: Index2, Edges-only, specifies an end point (0 or 1).
|
GetY(Structure, [Index1], [Index2]) |
Returns the y-coordinate from the indexed Annulus, Circle, Cross, Fixture, Fixtures, Line, Point or Region structure. Note: Index2, Edges-only, specifies an end point (0 or 1).
