                               throws EdalException

Draws the data into the supplied image.

Parameters:

image - A BufferedImage to draw into

dataReader - A GriddedImageLayer.MapFeatureDataReader which is used to obtain the actual data values and domain. The MapDomain returned will match the size of the image, and pixels are georeferenced to the GridCell2Ds which comprise the domain

Throws:

EdalException - If there is a problem reading the data or drawing into the image
