HP L 5 manual Bytes 3, 4, and 5 No. of Bits for Components 1, 2, Bits/Index Indices/Byte

•In the Indexed-by-Pixel PEM, where the raster data is interpreted as palette indices, this value determines how to interpret the byte-ordered row transfers. The following list shows how each byte is translated into indices:

Bits/Index	Indices/Byte
1	8
2	4
4	2
8	1

•In the Direct-by-Plane and Direct-by-Pixel PEMs, byte 2 does not apply to the raster format.

Bytes 3, 4, and 5 (No. of Bits for Components 1, 2, and 3)

These bytes are ignored for the Indexed by Plane and Indexed Direct PEMs. For the Direct by Plane PEM they must be set to one bit per component. For the Direct by Pixel PEM, they must be set to eight bits per component.
