ErrImageTile

public class ImageTile
extends OMScalingRaster
implements java.io.Serializable

This is an extension to OMRaster that automatically scales itself to match the current projection. It is only lat/lon based, and takes the coordinates of the upper left and lower right corners of the image. It does straight scaling - it does not force the image projection to match the map projection! So, your mileage may vary - you have to understand the projection of the image, and know how it fits the projection type of the map. Of course, at larger scales, it might not matter so much. This class was inspired by, and created from parts of the ImageLayer submission from Adrian Lumsden@sss, on 25-Jan-2002. Used the scaling and trimming code from that submission. That code was also developed with assistance from Steve McDonald at SiliconSpaceships.com.
