Field Detail

parent

protected KMLGroundOverlay parent

attributesResolved

protected boolean attributesResolved

textureResolved

protected boolean textureResolved

Indicates that the source texture has been resolved and loaded.

iconRetrievalTime

protected long iconRetrievalTime

Indicates the time at which the image source was specified.

mustApplyRotation

protected boolean mustApplyRotation

Constructor Detail

KMLSurfaceImageImpl

public KMLSurfaceImageImpl(KMLTraversalContext tc,
                           KMLGroundOverlay overlay)

Create an screen image.

Parameters:

tc - the current KMLTraversalContext.

overlay - the Overlay element containing.

Throws:

java.lang.NullPointerException - if the traversal context is null.

java.lang.IllegalArgumentException - if the parent overlay or the traversal context is null.

Method Detail

preRender

public void preRender(KMLTraversalContext tc,
                      DrawContext dc)

Description copied from interface: KMLRenderable

Pre-render this element.

Specified by:

preRender in interface KMLRenderable

Parameters:

tc - the current KML traversal context.

dc - the current draw context.

mustResolveHref

protected boolean mustResolveHref()

Indicates whether or not the image source needs to be resolved. The source needs to be resolved when the KMLIcon is updated.

Returns:

True if the image source must be resolved.

resolveHref

protected java.lang.String resolveHref()

Resolve the HREF in this overlay's Icon element against the KML root.

Returns:

The resolved path to the image source.

render

public void render(KMLTraversalContext tc,
                   DrawContext dc)

Render this element.

Specified by:

render in interface KMLRenderable

Parameters:

tc - the current KML traversal context.

dc - the current draw context.

applyRotation

protected void applyRotation(DrawContext dc)

Apply a rotation to the corner points of the overlay.

Parameters:

dc - Current draw context.
