8-9 8-9 LEN Length of Created Segment
10-13 A-D NAME Predecessor/Successor Name (The Printer Ignores This Field)
14-n E-n ORDER Drawing Order or Orders (The Number of Bytes in This Field
Must Equal the Length Field, Bytes 8-9)
If bit 3 of byte 7 is on, a prologue is the first sequence of drawing orders in a new segment. The prologue,
if present, is always at the beginning of a new segment's data and ends by an End Prologue order within
the same segment.
If bits 5 and 6 of byte 7 are zero, the drawing attributes are re-initialized to the current default values. If
bits 5 and 6 of byte 7 are equal to 11, this segment appends to the previous segment and the current
drawing attributes do not reinitialize.
Drawing Orders: One or more drawing orders follow each Begin Segment Introducer. The format of a
drawing order is:
Order Code
Order Code Parameter(s)
Order Code Length Parameter(s)
The order code specifies the type of graphics to print or the assigned drawing attribute.
The Length field, if present, is a one byte value that specifies the length of the drawing order following this
byte. See the specific drawing orders for information about the length field.
