## D.2 Various Additional Examples of Pixel and Overlay Data Cells

The following examples further illustrate the use of the data elements for Bits Allocated (0028,0100), Bits Stored (0028,0101) and High Bit (0028,0102) in the encoding of Pixel and Overlay Data. All examples show sample Pixel Cells before being encoded in byte streams (and before being affected by a particular Transfer Syntax).

Figure D.2-2 Example 2 of Pixel and Overlay Data Cells has been retired. See PS3.3 2014c.

### Note

In this example, the Overlay Bits are numbered in the same manner that Pixel Cells are numbered in the other examples in this Annex. That is Overlay Bit 1 is the first bit of the Overlay Plane, encoded from left to right and top to bottom, a row at a time.
