Detailed Description

The IRasterPropertyDictionary exposes a dictionary style interface to the raster properties. Through this interface the non-standard properties of a raster image can be determined and their values can be retrieved and set. Data values are exchanged through the DataValue object to accommodate various data types, boolean, integer, double, string etc.

Public Member Functions

__property
OSGeo::FDO::Expression::DataValue
get_Property (System::String *name)
 Gets the value of the specified property (or its default).
__property
OSGeo::FDO::Schema::DataType 
get_PropertyDataType (System::String *name)
 Gets the data type for the specified property.
__property
OSGeo::FDO::Expression::DataValue
get_PropertyDefault (System::String *name)
 Gets the default value for the specified property.
__property
OSGeo::FDO::Common::StringCollection
get_PropertyNames ()
 Gets the names of all the properties that apply to this image as a collection of Strings. The order of the property names in the collection dictate the order in which they need to be specified. This is especially important for the success of the EnumeratePropertyValues method as properties that occur earlier in the collection may be required for successful enumeration of properties that appear later in the collection.
__property
OSGeo::FDO::Raster::DataValueCollection
get_PropertyValues (System::String *name)
 Access the values of the specified enumerable property. The property must respond TRUE to IsPropertyEnumerable.
 IRasterPropertyDictionaryImp (System::IntPtr unmanaged, System::Boolean autoDelete)
 Constructs a IRasterPropertyDictionaryImp object based on an unmanaged instance of the object.
System::Boolean IsPropertyEnumerable (System::String *name)
 Predicate to determine if the property is enumerable (has more than one value).
System::Boolean IsPropertyRequired (System::String *name)
 Predicate to determine if the property is required to be set.
__property System::Void set_Property (System::String *name, OSGeo::FDO::Expression::DataValue *value)
 Sets the value of the specified property.
__property System::Void set_PropertyValues (System::String *name, OSGeo::FDO::Raster::DataValueCollection *collection)
 Set the values of the specified enumerable property. The property must respond TRUE to IsPropertyEnumerable. Clients will need to use SetPropertyValues when creating an image with specific values for the enumerable property. An example would be setting a table of wavelength ranges corresponding to the false colour used to encode the image.
