Parameters
- arr
- The new data array to use
The size of the array is not necessarily checked for consistency with w and h or any other fields.
Each implementing class should provide a type specific equivalent method (e.g., setDataInt() in GrapeCity.Documents.Imaging.jpeg.jj2000.j2k.image.DataBlkInt) which takes an array of the correct type explicitly and not through an System.Object.
