Direct Known Subclasses:

EsriIconPoint, TemporalOMScalingIcon

public class OMScalingIcon
extends OMScalingRaster
implements java.io.Serializable

This is an extension to OMScalingRaster that scales an icon. The icon is automatically centered over the lat/lon location. The offsets push the icon away from the lat/lon.

Method Detail

position

protected boolean position(Projection proj)

Since the image doesn't necessarily need to be regenerated when it is merely moved, raster objects have this function, called from generate() and when a placement attribute is changed.

Overrides:

position in class OMScalingRaster

Parameters:

proj - projection of window.

Returns:

true if enough information is in the object for proper placement.

isOnMap

public boolean isOnMap(Projection proj)

Description copied from class: OMScalingRaster

Test to see if projected image is on map.

Overrides:

isOnMap in class OMScalingRaster

Parameters:

proj - current projection

Returns:

true of projected image location intersects map area.

scaleTo

protected void scaleTo(Projection thisProj)

Over-riding this so we don't clip rotated icons near the edge of the map. Just display icons as whole.

Overrides:

scaleTo in class OMScalingRaster

Parameters:

thisProj - the projection that the image should be scaled to.

renderImage

protected void renderImage(java.awt.Graphics g,
                           java.awt.Image image,
                           java.awt.Point loc)

Render the image at the given pixel location. This method should be overridden for special Image handling.

Overrides:

renderImage in class OMScalingRaster

Parameters:

g - the Graphics object to render the image into. Assumes this is a derivative of the Graphics passed into the OMGraphic, and can be modified without worrying about passing settings on to other OMGraphics.

image - the image to render.

loc - the pixel location of the image.

setBaseScale

public void setBaseScale(float bs)

getBaseScale

public float getBaseScale()

setMaxScale

public void setMaxScale(float ms)

Set the scale that limits how small an icon will shrink. Should be a number larger than the base scale. If the map scale gets larger than this number, the icon will stop shrinking.

getMaxScale

public float getMaxScale()

setMinScale

public void setMinScale(float ms)

Set the scale that limits how big an icon should grow. Should be a number smaller than the base scale. If the map scale gets smaller than this number, the icon will stop growing.

getMinScale

public float getMinScale()

restore

public void restore(OMGeometry source)

Description copied from class: OMGraphicAdapter

Takes the generic OMGraphic settings from another OMGraphic and pushes them to this one.

Specified by:

restore in interface OMGeometry

Overrides:

restore in class OMScalingRaster
