Méthodes publiques

Méthode Description
BeginConstruction ( IDataSourceCrawler pCrawler ) : void

Prepare the Raster Type for generating Crawler items
Build ( IItemURI pItemURI ) : IBuilderItem

Call the build function of the inner Raster Type and generate a thumbnail from the Builder Item created.
ConstructURIs ( object crawlerItem ) : void

Construct a Unique Resource Identifier (URI) for each crawler item
EndConstruction ( ) : IItemURIArray

Finish Construction of the URI's
GetNextURI ( ) : IItemURI

Generate the next URI.
GetRecommendedCrawler ( IPropertySet pDataSourceProperties ) : IDataSourceCrawler

Get the recommended data crawler for the Raster Type based on properties provided by the user.
IPersistVariant ( IVariantStream Stream ) : void

Load the object from the stream provided
IsStale ( IItemURI pItemURI ) : bool

Check if the item provided is "stale" or not valid
ThumbnailBuilder ( ) : System

Private Methods

Méthode Description
AddingNewField ( IFields myFields ) : void

The following function creates a field called "ThumbNail" and adds it to the existing fields in the mosaic dataset catalog as a blob.
Resampling ( IBuilderItem mybuilderItem ) : void

Each BuilderItem contains a Function Raster Dataset which is used to create the thumbnail. The thumbnail is created by Nearest Neighbor resampling of the Function Raster Dataset. The resampled raster is exported as a byte array and saved Into the IMemoryBlobStreamVariant. The blob is then inserted into the Thumbnail field.
