Class AffineTransControlPointExtracter

java.lang.Object

com.vividsolutions.jump.plugin.edit.AffineTransControlPointExtracter

public class AffineTransControlPointExtracter
extends java.lang.Object

Uses geometry data in two FeatureCollections to extract parameters for an affine transformation. The contents of the layers determines how the parameters are extracted. The layers can contain:

• A 2-point vector - parameters will have isometric scaling and no shear
• A 3-point LineString - a general affine transformation will be computed
• (FUTURE) 1, 2 or 3 points, each with a tag value - the affine transformation will be computed from the mappings between the points.
