Class RpfSubframe

java.lang.Object
  com.bbn.openmap.layer.rpf.RpfSubframe

public class RpfSubframe
extends java.lang.Object

The RpfSubframe is a holder for images and attributes within the cache.

Nested Class Summary

class	RpfSubframe.BitsAndColors Indexed colormodel implementation.
class	RpfSubframe.ImageCreator
class	RpfSubframe.Pixels Direct colormodel implementation.

Field Summary

protected DataBounds	bounds
protected java.lang.String	data The actual attribute information.
protected RpfSubframe.ImageCreator	imageCreator The object that creates the image from either pixels or bytes and colors.
int	nextSubframe The pointers to the surrounding subframes in the cache.
protected int	opaqueness The opaqueness of the image.
static int	PIXEL_EDGE_SIZE The original pixel size of RPF Subframes.
int	prevSubframe The pointers to the surrounding subframes in the cache.
byte	version The version of the subframe, used by the cache for marking how recently used the subframe was.

Method Detail

setLocation

public void setLocation(double ulat,
                        double wlon,
                        double llat,
                        double elon)

Set the lat/lon of the frame and attribute text.

Parameters:

ulat - latitude of upper left point, in decimal degrees.

wlon - longitude of upper left point, in decimal degrees.

llat - latitude of lower right point, in decimal degrees.

elon - longitude of lower right point, in decimal degrees.

setAttributeText

public void setAttributeText(java.lang.String text)

setScalingTo has to be called after this for the changes to take place, or else you need to call the information.setData() methods directly.

getAttributeText

public java.lang.String getAttributeText()

getAttributeText retrieves the text that would be displayed as attribute information about the subframe.

setPixels

public void setPixels(int[] pixels)

setBitsAndColors

public void setBitsAndColors(byte[] bits,
                             java.awt.Color[] colors)

setTransparent

public void setTransparent(int opaqueness)

getImage

public OMGraphic getImage(Projection proj)
