Description

Get data points that are inside the enclosed rectangle

Syntax

int GetRectPoints( fpoint & fptTopLeft, fpoint & fptBottomRight, vector & vX, vector & vY, vector<int> * pvnIndices = NULL )

Parameters

fptTopLeft: [input] top-left point of specific retangle
fptBottomRight: [input]bottom-right point of specific retangle
vX: [output] x coordinates of the found points
vY: [output] y coordinates of the found points
pvnIndices: [output] indices of the found points

Return

number of data points found or < 0 for error codes

Examples
