Description copied from interface: FLayer

Prints this layer according to some properties requested.

Specified by:

print in interface FLayer

Parameters:

g - for rendering 2-dimensional shapes, text and images on the Java(tm) platform

viewPort - the information for drawing the layers

cancel - an object thread that implements the Cancellable interface, and will allow to cancel the draw

scale - the scale of the view. Must be between FLayer.getMinScale() and FLayer.getMaxScale().

properties - a set with the settings to be applied to a whole print job and to all the docs in the print job

Throws:

org.gvsig.fmap.dal.exception.ReadException - if fails the driver used in this method.
