 Last update: 17.07.2025 

## Description

Returns an array of 5 VARIANT of the values for the given line in the following order: minimum value, maximum value, average, Range X, Range Y.

## Syntax

*object*.SurfaceLineCalculation(double dXPos1, double dYPos1, double dXPos2, double dYPos2, double dSampling, double dThresholdLevel) As Variant

- *object*: Virtual Photometric Lab object
- *dXPos1*: horizontal coordinate of the first vertex of the line
- *dYPos1*: vertical coordinate of the first vertex of the line
- *dXPos2*: horizontal coordinate of the second vertex of the line
- *dYPos2*: vertical coordinate of the second vertex of the line
- *dSampling*: distance between two measurement points on the map (for example the result returned by XSampleWidth or YSampleHeight)
- *dThresholdLevel*: Iso level defined to measure the range X and Y
