Constructor Detail

MapImage

public MapImage()
         throws IOException,
                UnknownHostException
Constructs a MapImage using ArcGIS Engine.

Throws:
IOException - if there are interop problems
UnknownHostException - if there are interop problems

MapImage

public MapImage(Object obj)
         throws IOException
Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
MapImage theMapImage = (MapImage) obj;

Construct a MapImage using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to MapImage.

public IEnvelope getMapExtent()
                       throws IOException,
                              AutomationException

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getMapExtent in interface IMapImage
Returns:
A reference to a com.esri.arcgis.geometry.IEnvelope

getVisibleLayers

public ILongArray getVisibleLayers()

                                   AutomationException
Array of the visible layers drawn for the generated map scale.

Remarks

VisibleLayers is defined by a combination of layer visibility in the TOC (i.e. is the layer "on"?) and layer visibility dependent on map scale. Scale dependency for a layer is set in the original map document. If the layer is scale dependent (i.e. a maximum and/or minimum scale has been set) and the map scale falls out of this range, layer visibility will be false. Do not confuse this property with the visibility property on ILayerDescription which is based solely on layer visibility in the TOC (is the layer "on" or "off"). The IMapImage interface inherits all IImageResult properties.

Specified by:
getVisibleLayers in interface IMapImage
