| Property | Type | Description | |
|---|---|---|---|
| AddingNewField | void | ||
| Resampling | void |
| Method | 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 |
| Method | 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.
