Examples of jxl.write.WritableImage

jxl.write.WritableImage
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
