Raster.Data Property
Gets a reference to the read/write raster data.
Syntax
public System.IO.Stream Data { get; }Property Value
The read/write raster data.
Remarks
This property gives an application direct read/write access to the data buffer held by the Raster instance. If you only require read access to the data, use the ReadOnlyData property instead, as the Data property may throw an exception if the raster itself is read-only. If you need to modify the raster data, for instance in a custom operator, first check if the feature is read-only using Feature.IsReadOnly, and then clone the feature if necessary before accessing the raster data.
This property will return a new object instance, that keeps the underlying raster data alive, each time it is accessed. To make sure this data is properly garbage collected, use the following pattern in a .NET application:
// Read the property once
using (var data = aRaster.Data)
{
// Access properties and methods through the local variable
long length = data.Length;
data.Write(..);
data.Read(...);
}
// The local variable has now been disposed automatically
