Data # get (ColorResolutionCommandDataEventArgs)
The buffer containing one or more lines of output image data that the command has already converted.
This property returns the data in an unmanaged buffer. You can use the Marshal.Copy method to copy this data to a managed buffer.
To get the data in a managed array, use the DataArray property.
