Examples of mxGeometry

com.mxgraph.model.mxGeometry
Represents the geometry of a cell. For vertices, the geometry consists of the x- and y-location, as well as the width and height. For edges, the geometry either defines the source- and target-terminal, or it defines the respective terminal points. For edges, if the geometry is relative (default), then the x-coordinate is used to describe the distance from the center of the edge from -1 to 1 with 0 being the center of the edge and the default value, and the y-coordinate is used to describe the absolute, orthogonal distance in pixels from that point. In addition, the offset is used as an absolute offset vector from the resulting point.
