Layer containing a Basemap.

Remarks

A basemap layer is a user-defined group of layers, which are drawn continuously during navigation. BasemapLayer implements IGroupLayer and in many ways it behaves in the same way as GroupLayer. BasemapLayer draws with a high-performance drawing engine that can significantly improve the display speed and responsiveness of your map. ArcMap is the primary consumer of BasemapLayer; however, the MapControl and ArcReader also have the same performance benefits when working with BasemapLayer. Components using the output pipeline of the ArcGIS 2D drawing engine, such as ArcGIS Server and the 3D applications drawing draped content, will not see a benefit from using BasemapLayer. Optimized map services in ArcGIS Server use the same drawing engine as BasemapLayer and should be used to achieve fast map services.

public boolean isUsesFilter()

                            AutomationException

Indicates if the current object draws using a filter.

Remarks

The UsesFilter property returns true when the object in question will draw with a filter. Drawing with a filter means means that an object that would normally draw as vector graphics will instead draw as raster. The UsesFilter property is particularly useful for detecting vector map layers that will be rasterized at time of print or export.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

isUsesFilter in interface IDisplayAdmin

Specified by:

isUsesFilter in interface IDisplayAdmin2

Indicates whether the output from the drawing object requires banding. Generally this is true if the output is raster.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

isRequiresBanding in interface IDisplayAdmin2

Returns:

The flag

Throws:

IOException - If there are interop problems.

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

isDoesBlending in interface IDisplayAdmin2

Returns:

The flag

Throws:

getSpatialReference

public ISpatialReference getSpatialReference()

                                             AutomationException

The spatial reference of the GeoDataset.

Remarks

This property is read only. For layers, when the first layer is added to ArcMap, its spatial reference is read by this property, and the map is set to this spatial reference.

Instances of the esriCarto.GroupLayer class will return null for this property, as a group layer can contain multiple datasets with different spatial references.

Modifications to a spatial reference returned by this property will not be persisted. To modify the spatial reference of a dataset, the IGeoDatasetSchemaEdit and IGeoDatasetSchemaEdit2 interfaces should be used.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getSpatialReference in interface IGeoDataset

Returns:

A reference to a com.esri.arcgis.geometry.ISpatialReference

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getExtent

public IEnvelope getExtent()
                    throws IOException,
                           AutomationException

The extent of the GeoDataset.

Remarks

The IGeoDataset::Extent property returns an envelope representing the maximum extent of data which has been stored in the dataset.

Consider the following scenario. A new feature class has features added to it. The IGeoDataset::Extent is then requested and an envelope is returned. The extents of the envelope returned are represented by the red box in the image below.

If a portion of the features were then deleted and the extent is again requested an envelope with the exact same extents as during the first request would be returned (see image below). This is because the deletion of features does not shrink the extent. However all additions of features outside the red box would increase the envelope returned to encompass the newly added features.

If you would like to update the IGeoDataset::Extent property to reflect the current features in your dataset please see IFeatureClassManage::UpdateExtent (also see IFeatureClassLoad). In the image below the extent has been updated and a new envelope is being returned.

ESRI's GroupLayer implements this property differently from most other layer coclasses. When you instantiate a new GroupLayer, this property will return a valid envelope with zero height and width. With most other newly instantiated layers (for example FeatureLayer, RasterLayer, TinLayer), this property initally returns Nothing.

Specified by:
