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.
