7–108 Digital Emulation
Sixel Graphics Processing
A sixel is a group of six vertical picture elements (six pixels) that represents
a section of a graphic image. It can be sent in one byte (7 or 8 bits). A bit
value of 1 means print a pixel; a bit value of 0 means leave a space.
The sixel protocol is a bit–imaged rasterised method of transmitting and
displaying graphic images. The printer receives and prints sixel files sent
from the host. These images are printed in monochrome.
NOTE: Sixel graphics is invoked in one of two ways: for use with the new
software and for use with older software versions. This section
describes how to run sixel graphics with the new software. If you
are running older software versions, refer to the appropriate Digital
manual for sixel graphics information.
Sixel protocol is contained within an ANSI defined Device Control String
(DCS) control code. It is invoked by a String Introducer (SI) and is
terminated by the String Terminator (ST) control code. The following
components make up the complete Device Control String for the sixel
protocol:
1. String Introducer
2. Protocol Selector
3. Picture Data
4. String Terminator
The Device Control String is assembled as follows:
DCS Ps1 ; Ps2 Pn3 ... Pn q <Sixel data> ST;
