PixelY2 Result
Applies To
Vision Objects: BoxFinder, Line, LineFinder
Description
- Line, LineFinder: Returns the pixel Y coordinate of the end point of a Line object.
- BoxFinder: Returns the Y (Y2) coordinate position for corner points of rectangles detected in a pixel coordinate system.
Usage
VGet Sequence.Object.PixelY2[(result)], var
- Sequence
- Name of a sequence or string variable containing a sequence name.
- Object
- Name of an object or string variable containing an object name. The object must exist in the specified sequence.
- var
- Real variable that will contain the value of the result.
- result
- Optional result number. If omitted, the result number is the CurrentResult. Used for objects that return multiple results.
Values
Min: 0
Max: ImageSize height - 1
Remarks
For Line, LineFinder
Every line has a starting point and ending point. The PixelY1 and PixelY2 results represent the Y coordinate position starting (Y1) and endpoints (Y2) of the specified Line object. Since Line object starting and endpoints can be assigned to other vision objects, the (PixelX1, PixelY1) and (PixelX2, PixelY2) coordinate pairs can actually be pixel coordinate positions which match the PixelX and PixelY results for other vision objects. (In other words if a Line object's endpoint is defined by a Correlation object, then the (PixelX, PixelY) results from the Correlation object will match the (PixelX2, PixelY2) results for the Line object.)
For BoxFinder
The pixel coordinates for the four corners of a rectangle can be retrieved as Pixel X1, 2, 3, 4 results and Pixel Y1, 2, 3, 4 results. PixelY2 is used to retrieve the Y coordinate for the Corner2 point shown in the diagram below.
