CREATING AND PRINTING A RASTER FILL PATTERN
The Raster Fill ( RF ) Command is used to define a fill
pattern to be used in other fill commands. The RF
command does not select a fill type, it defines a user
created fill type that can then be selected using the
Fill Type ( FT ) command, with a type parameter of 11
and the corresponding raster fill index number for the
second parameter. For example FT11,3; for the index
number 3. For more information see the PCL 5 Printer
Language Technical Reference Manual. The syntax for
the RF command is as follows:
RF index,width,height,pen number....pen number; or RF
index; or RF;
PARAMETERS:
Index Specifies the index
number of the pattern
being defined.
Width and Height Specifies the width and
height in pixels of the
pattern being defined.
Pen Number Represents a pixel in the
pattern being defined and
indicates its color,
black (>0) or white (0).
This parameter defines
pixels left to right, top
to bottom, and the total
number of pen number
parameters should be
equal to the width times
the height parameter. For
example, to define a
pattern that is 8 x16
pixels, you need 128 pen
number parameters. If not
all pen parameters are
specified, the remainder
parameters default to
zeros (white). The
pattern that is created
is printed in rows
parallel to the plotter-
units X-axis.
PROGRAM:
LEGEND: Ec = [Ctrl] [P] [Esc] in DOS EDIT.
EcE Resets the printer.
Ec%0B Enters HP-GL/2 mode.
IN; Initializes HP-GL/2 mode.
SP1; Selects pen number 1,
(black). Even though
there is no physical pen,
the SP command must be
used to enable printing.
PU5,5; Lifts the pen and moves
to absolute position
(5,5).
PA3500,2500: Specifies absolute
plotting and moves to
(3500,2500).
RF2,8,4,0,0,0,0,0,0,0,0,0,0,
0,1,1,0,0,0,0,0,0,1,1,0,0,0
0,0,0,0,0,0,0,0; Defines a raster fill
pattern (index number 2)
that is 8 dots wide by 4
dots high. The dots are
shown as they will appear
in the pattern, they
should ,be inputted into
the program, on one line
FT11,2; Selects the user-defined
pattern just specified in
the command above, with
the index number of 2.
RR4000,800;EP; Fills a rectangle with
the fill pattern just
specified by the FT
command, with the lower
left corner at
(3500,2500) and upper
right 4000 plotter units
(plu) to the right and
800 plu up from that
location. The EP command
edges the polygon just
drawn.
Ec%0A Enters the PCL mode.
EcE Sends a reset to end the
job and eject the page.
