EN Raster Graphics 6-17
Start Raster Graphics Command
The Start Raster Graphics command identifies the beginning of the
raster data and also specifies the left graphics margin.
? * r # A
A value of 0 specifies that the left graphics margin is at the default left
margin of the page (X-position 0). A value of 1 specifies that the left
graphics margin is at the current X-position. Values of 2 or 3 are
equivalent to 0 and 1, but also enable resolution-independent scaling.
In presentation mode 3, the location of the left graphics margin varies
depending on the orientation.
Once a Start Raster Graphics command is received by the printer,
raster graphics resolution, raster graphics presentation mode, raster
height, raster width, and left raster graphics margin are fixed until an
end raster graphics command is received.
Once in Raster Graphics Mode, PCL commands and text imply an
End Raster Graphics (
?*rC) except for the following commands:
• Transfer Raster Data by Row or by Plane
• Set Raster Compression Method
• Raster Y Offset
In addition, the following commands are ignored (i.e., locked out)
while in Raster Graphics Mode and do not imply an End Raster
Graphics command:
• Start Raster Graphics
• Set Raster Width
• Set Raster Height
• Set Raster Presentation Mode
# = 0 - Start graphics at default left graphics margin
(X-position 0).
1 - Start graphics at current cursor position (current
X-position).
2 - Raster scaling on—start at left boundary.
3 - Raster scaling on—start at CAP.
Default =0
Range = 0 - 3 (out-of-range values default to 0)
