DECGRI (!)
Chapter 8. PPL3 Plus Emulation
Graphics Repeat Introducer: Repeats the following sixel a specified
number of times.
Format
! Pn
Description
The printer repeats the sixel following the DECGRI sequence Pn
times.
The repeat function supports parameters large enough to cover the
largest print line at the smallest grid size, up to 32K.
The following examples illustrate repeat sequences:
! 1 0 ?
! 6 @
Error Handling
A repeat count of zero or omitted is treated as a repeat count of one.
Values that exceed the maximum value are treated as the maximum
value. If no sixel printable character follows the repeat count, the
repeat count is ignored.
If a graphics control code is received within a DECGRI sequence, the
repeat sequence is ignored. This includes sequences in the range 21
to 2F, 3A, and 3C to 3E. If multiple parameters are received
(separated by semicolons), the printer uses the first parameter and
ignores the rest.
