Adapter object, specified as an instance of an adapter class that is subclassed from the images.blocked.Adapter class.

Structure containing information about source, returned as a structure with these fields.

Field	Description
`Size`	An L-by-N integer-valued array representing image size(s); For this field and all subsequent fields,L is the number of levels in `Source`. For a single resolution level image L is 1. N is the number of dimensions in the image.
`IOBlockSize`	An L-by-N integer-valued array representing the smallest unit of data that can be read from the source.
`Datatype`	An L-by-N string array containing the MATLAB^® datatype for each level.
`InitialValue`	A scalar value of type specified by `Datatype`, indicating the initial data value for each level. If the types and values differ for a multiresolution array, this can be a cell array.

You can optionally return these additional fields.

Optional Field	Description
`UserData`	A scalar `struct` containing additional metadata about the source. This field can be empty.
`WorldStart`	An L-by-N numeric array specifying the starting edge location of the image in world coordinates.L is the number of levels in `Source`. N is the number of dimensions in the image.
`WorldEnd`	An L-by-N numeric array specifying the ending edge location of the image in world coordinates.L is the number of levels in `Source`. N is the number of dimensions in the image.
