This PlugIn can be used to load image files for background use. The images are automatically scaled to fit the projection. The actual accuracy of matching the scaled images to the map depends on the projection of the images, and the projection type being used for the map. At larger scales, the error may not be noticeable.
This PlugIn uses a csv file to find out about the images that should be loaded. The layer assumes that the csv file has these fields, in this order:
Upper Latitude, Western Longitude, Lower Latitude, Eastern Longitude, URL of image 42,-73.5,40,-72,file:///data/images/test1.jpg 40,-73.5,38,-72,file:///data/images/test2.jpgMake sure there are not spaces in the data portion of the file!
The properties for the PlugIn look like this:
plugin.class=com.bbn.openmap.plugin.CSVTiledImagePlugIn plugin.prettyName=Name of Layer # URL of the data file plugin.tileFile=URL of csv file # If the csv file has descriptive header line that should not be used for images. (default = true) plugin.fileHasHeader=trueThe PlugIn doesn't do anything fancy with image caching. The plugin loads all of the images when the layer is turned on. You might have to bump up the heap size of the JVM when loading large or many images.
This class was inspired by, and created from parts of the ImageLayer submission from Adrian Lumsden@sss, on 25-Jan-2002. Use the MediaTracker code from that class.
