Class WorldFileWriter

Object

WorldFileWriter

public class WorldFileWriter
extends Object

This class is responsible for creating a world file from a MathTransform or AffineTransform.

The content of a world file describes an affine transformation which was used by the ESRI software to map from the rater world to the spatial world (what we usually call a grid to world transform).

Specifically a world file should be as follows:

scalex shearx sheary scaley upperleftx upperlefty

which translates into the following affine transformation.

| : | | scalex shearx : translatex| | : | | sheary scaley : transaltey| |----------------------------| | 0 0 : 1 | | : |

Note that a world file usually takes as reference the centre of the pixel.
