\title{qgraph Cent2Edge (EXACT - critical formula)}
\usage{
qgraph_cent2edge(x, y, cex, offset = 0, angle, plot_info = NULL)
}
\arguments{
\item{x}{Node center x coordinate.}

\item{y}{Node center y coordinate.}

\item{cex}{Node size (vsize value, not yet scaled).}

\item{offset}{Additional offset distance.}

\item{angle}{Angle from node center to target point (radians).}

\item{plot_info}{Plot dimension info from qgraph_plot_info(). NULL to auto-compute.}
}
\value{
List with x, y coordinates on node boundary.
}
\description{
Calculates the point on node boundary where an edge should connect.
This is qgraph's exact formula for positioning arrows and edge endpoints.
