    FieldDescription
    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.

    IOBlockSizeAn L-by-N integer-valued array representing the smallest unit of data that can be read from the source.
    DatatypeAn L-by-N string array containing the MATLAB datatype for each level.
    InitialValueA 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 FieldDescription
    UserData

    A scalar struct containing additional metadata about the source. This field can be empty.
