Remarks

 

 

 

 

 

 

DECGRA

Set Raster Attributes

" (2/2)

Defines the pixel aspect ratio.

 

 

 

 

Followed by parameters

 

 

 

 

Pn1 ; Pn2 ; Pn3 ; Pn4

 

 

 

 

Pn1 : Pixel aspect ratio numerator

 

 

 

 

Pn2 : Pixel aspect ratio denominator

 

 

 

 

Pn3 and Pn4 : ignored

 

DECGRI

Graphics Repeat

! (2/1)

Followed by a numeric value Pn and a

 

 

Introducer

 

sixel data to be repeated Pn times.

 

DECGCR

Graphics Carriage

$ (2/4)

Returns active position to graphics

 

 

Return

 

left margin.

 

DECGNL

Graphics Next Line

(2/13)

Returns active position to graphics

 

 

 

 

left margin and increments to next

 

 

 

 

graphics line.

 

DECGCI

Graphics Color

# (2/3)

Assigns a color to a color number or

 

 

Introducer

 

selects a predefined color number.

 

 

 

 

Followed by parameters

 

 

 

 

Pc ; Pu ; Px ; Py ; Pz

 

 

 

 

Pc : Color number (0 - 255)

 

 

 

 

Pu : Universal coordinate system

 

 

 

 

selector : 1 = HLS

 

 

 

 

2 = RGB

 

 

 

 

Px , Py , Pz : color coordinates

 

 

Parameter Characters

0 - 9

Numeric parameters - used on the

 

 

 

(3/0 - 3/9)

above control codes

 

 

Parameter Separator

; (3/11)

Separates parameters - used on the

 

 

 

 

above control codes

 

 

Sixel Data

(3/15 - 7/14)

Sixel printable characters.

 

 

 

 

The printer substracts the offset (3F

 

 

 

 

hexadecimal) from the received code,

 

 

 

 

assigning each of the remaining low-

 

 

 

 

order six bits to a grid position :

 

 

 

 

LSB = top pixel

 

 

 

 

MSB = bottom pixel

 

 

 

 

Examples :

 

 

 

 

? (3/15) : blank character

 

 

 

 

@ (4/0) : print only top pixel

 

 

 

 

A (4/1) : print second-from-top pixel

 

 

 

 

~ (7/14) : print one full column
