FILLING THEN EDGING VS EDGING THEN FILLING When transparency mode ( TR command ) is opaque, filling then edging an object may produce different results than edging and then filling. This is especially true when large pen widths are used. The following example illustrates this. For more information see the PCL 5 Printer Language Technical Reference Manual. NOTE: The following program will draw two circles using different sequences to fill then edge. The circle that is drawn on top is filled then edged, while the circle on the bottom is edged then filled. 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. TR0; Sets transparency mode off (opaque). PU4000,6000; Moves the pen to coordinate (4000,6000). PW5; Selects a pen width of 5 plotter units (plu). PM0; Enters polygon mode. CI1000; Draws a circle with a radius of 1000 plu. PM2; Closes polygon and exits polygon mode. FT10,30; Selects 30% shading fill type. FP;EP; Fills then edges the polygon, (circle). PU4000,3000; Moves the pen to location (4000,3000). PM0; Enters polygon mode. CI1000; Draws another circle with a radius of 1000 plu. PM2; Closes the polygon and exits polygon mode. EP;FP; Edges then fills the polygon, (circle). Ec%0A Enters PCL mode. EcE Sends a reset to end the job and eject the page.
