If you pass a valid instance of Leadtools.Codecs.RasterCodecs in the DocumentReaderLoadOptions.RasterCodecsInstance property of the object passed to the options parameter to DocumentReader.Create, then the same object be saved internally and used by the document reader and accessed here. In this mode, you must ensure that the original Leadtools.Codecs.RasterCodecs must be alive for the whole lifespan of this DocumentReader.
If the value of DocumentReaderLoadOptions.RasterCodecsInstance is null, then a new instance of Leadtools.Codecs.RasterCodecs will be created during DocumentReader.Create and assigned to this property. When the DocumentReader object is disposed, this Leadtools.Codecs.RasterCodecs instance is disposed as well. You can access this created Leadtools.Codecs.RasterCodecs object through this property as well.
