public class CSVTiledImagePlugIn
extends OMGraphicHandlerPlugIn

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.jpg

Make 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=true

The 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. Update: The MediaTracker has been replaced by ImageIO components in OpenMap 4.6.3.

Method Detail

### getRectangle

    public OMGraphicList getRectangle(Projection p)

  The getRectangle call is the main call into the PlugIn module. The module is expected to fill the graphics list with objects that are within the screen parameters passed.

  Specified by:
    `getRectangle` in interface `PlugIn`
  Overrides:
    `getRectangle` in class `OMGraphicHandlerPlugIn`
  Parameters:
    `p` - projection of the screen, holding scale, center coords, height, width.

### setProperties

    public void setProperties(java.lang.String prefix,
                              java.util.Properties props)

  PropertyConsumer method, setting the PlugIn with properties that apply to it.

  Specified by:
    `setProperties` in interface `PropertyConsumer`
  Overrides:
    `setProperties` in class `AbstractPlugIn`
  Parameters:
    `prefix` - a String used by the PropertyConsumer to prepend to each property value it wants to look up - setList.getProperty(prefix.propertyKey). If the prefix had already been set, then the prefix passed in should replace that previous value.
    `props` - a Properties object that the PropertyConsumer can use to retrieve expected properties it can use for configuration.

### loadTiles

    protected void loadTiles(java.lang.String csvFileName)

  Takes the URL to a csv file and parses it into OMScaledRasters, adding them to the tiles HashSet.

### getProperties

    public java.util.Properties getProperties(java.util.Properties getList)

  Method to fill in a Properties object, reflecting the current values of the PropertyConsumer. If the PropertyConsumer has a prefix set, the property keys should have that prefix plus a separating '.' prepended to each propery key it uses for configuration.

  Specified by:
    `getProperties` in interface `PropertyConsumer`
  Overrides:
    `getProperties` in class `AbstractPlugIn`
  Parameters:
    `getList` - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.
  Returns:
    Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

### getPropertyInfo

    public java.util.Properties getPropertyInfo(java.util.Properties list)

  Method to fill in a Properties object with values reflecting the properties able to be set on this PropertyConsumer. The key for each property should be the raw property name (without a prefix) with a value that is a String that describes what the property key represents, along with any other information about the property that would be helpful (range, default value, etc.).

  Specified by:
    `getPropertyInfo` in interface `PropertyConsumer`
  Overrides:
    `getPropertyInfo` in class `AbstractPlugIn`
  Parameters:
    `list` - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.
  Returns:
    Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.
