Class WritableImage

java.lang.Object
  jxl.biff.drawing.Drawing
      jxl.write.WritableImage

All Implemented Interfaces:

jxl.biff.drawing.DrawingGroupObject, Image

public class WritableImage

extends jxl.biff.drawing.Drawing

Allows an image to be created, or an existing image to be manipulated Note that co-ordinates and dimensions are given in cells, so that if for example the width or height of a cell which the image spans is altered, the image will have a correspondign distortion
