renderNow

void renderNow(DrawContext dc)

Draws the annotation immediately on the specified DrawContext. Rendering is not be delayed by use of the DrawContext's ordered mechanism, or any other delayed rendering mechanism. This is typically called by an AnnotationRenderer while batch rendering. The GL should have its model view set to the identity matrix.

Parameters:

dc - the current DrawContext.

Throws:

java.lang.IllegalArgumentException - if dc is null.

draw

void draw(DrawContext dc,
          int width,
          int height,
          double opacity,
          Position pickPosition)

Draws the annotation without transforming to its screen position, or applying any scaling. This Annotation is draw with the specified width, height, and opacity. The GL should have its model view set to whatever transformation is desired.

Parameters:

dc - the current DrawContext.

width - the width of the Annotation.

height - the height of the Annotation.

opacity - the opacity of the Annotation.

pickPosition - the picked Position assigned to the Annotation, if picking is enabled.

Throws:

java.lang.IllegalArgumentException - if dc is null.

getBounds

java.awt.Rectangle getBounds(DrawContext dc)

Get the annotation bounding Rectangle using OGL coordinates - bottom-left corner x and y relative to the WorldWindow bottom-left corner, and the annotation callout width and height.

The annotation offset from it's reference point is factored in such that the callout leader shape and reference point are included in the bounding rectangle.

Parameters:

dc - the current DrawContext.

Returns:

the annotation bounding Rectangle using OGL viewport coordinates.

Throws:

java.lang.IllegalArgumentException - if dc is null.

getMinActiveAltitude

double getMinActiveAltitude()

Returns the minimum eye altitude, in meters, for which the annotation is displayed.

Returns:

the minimum altitude, in meters, for which the annotation is displayed.

See Also:

setMinActiveAltitude(double), getMaxActiveAltitude()

setMinActiveAltitude

void setMinActiveAltitude(double minActiveAltitude)

Specifies the minimum eye altitude, in meters, for which the annotation is displayed.

Parameters:

minActiveAltitude - the minimum altitude, in meters, for which the annotation is displayed.

See Also:

getMinActiveAltitude(), setMaxActiveAltitude(double)

getMaxActiveAltitude

double getMaxActiveAltitude()

Returns the maximum eye altitude, in meters, for which the annotation is displayed.

Returns:

the maximum altitude, in meters, for which the annotation is displayed.

See Also:

setMaxActiveAltitude(double), getMinActiveAltitude()

setMaxActiveAltitude

void setMaxActiveAltitude(double maxActiveAltitude)

Specifies the maximum eye altitude, in meters, for which the annotation is displayed.

Parameters:

maxActiveAltitude - the maximum altitude, in meters, for which the annotation is displayed.

See Also:

getMaxActiveAltitude(), setMinActiveAltitude(double)
