Field Detail

attributesResolved

protected boolean attributesResolved

iconRetrievalTime

protected long iconRetrievalTime

Indicates the time at which the image source was specified.

mustApplyRotation

protected boolean mustApplyRotation

Flag to indicate the rotation must be applied to the SurfaceImage. Rotation is applied the first time that the image is rendered.

parent

protected KMLGroundOverlay parent

textureResolved

protected boolean textureResolved

Indicates that the source texture has been resolved and loaded.

Constructor Detail

KMLSurfaceImageImpl

public KMLSurfaceImageImpl(KMLTraversalContext tc,
                           KMLGroundOverlay overlay)

Create an screen image.

Parameters:

tc - the current KMLTraversalContext.

overlay - the Overlay element containing.

Throws:

NullPointerException - if the traversal context is null.

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

Method Detail

applyRotation

protected void applyRotation(DrawContext dc)

Apply a rotation to the corner points of the overlay.

Parameters:

dc - 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.

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.

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.

resolveHref

protected String resolveHref()

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

Returns:

The resolved path to the image source.
