This value is only present when the halftone uses two arrays to form a non-rectangular cell. It gives the column count of the second array. Each of its samples is two bytes wide.

When both Width2 and Height2 are supplied, the stream contains two back-to-back blocks: the first sized by Width and Height, the second by Width2 and Height2. The viewer uses both blocks together to build the cell.
