Marker; Marker At Current Position - IBM 6400 Programmer's Reference Manual

Graphics Command Set

Marker

Description: This order specifies one or more marker symbols to place at the
points specified by pairs of coordinates. The specified location is the center of
the marker.
A previously specified Set Marker Symbol order determines the marker symbol
the printer uses. If no previous Set Marker Symbol order was processed, the
printer uses the current graphics default marker symbol. The printer uses the
current values of color, mix, background mix, marker precision, marker set, and
marker symbol when drawing the markers.
L1 is a one-byte value that specifies the length of the parameter field that
follows. The value of L1 must be a multiple of four. If L1 equals zero, the printer
does not draw a marker.
Parameters P1 and P2 form a two byte value that specifies the X coordinate
point for the first marker. Parameters P3 and P4 form a two byte value that
specifies the Y coordinate point for the first marker. Parameters P5 to Pn, if
present, specify the X and Y coordinate points for additional markers.
This order updates the current graphics position to the coordinates of the last
end point.
Note: The marker cell size is constant 3 mm (0.12 in.
factor used in defining a graphics area does not affect the size of the marker. If
markers are used near the edge of a defined graphics area, scaling the graphics
may result in the markers being clipped from the printable graphics area.

Marker at Current Position

Description: This order specifies one or more marker symbols, which the
printer places at the points specified by a pair of X and Y coordinates, beginning
with the current graphics position. The Set Marker Symbol order determines the
marker that prints.
L1, the length, specifies the number of bytes following this byte. The value of L1
must be a multiple of four. A value of zero for L1 is valid and results in only one
marker symbol being drawn at the current graphics position.
Parameters P1 to Pn, if present, form two byte values that specify the X and Y
coordinates for each additional marker symbol. The printer draws the first
marker symbol at the current graphics position. P1 and P2 form a two byte
value that specifies the second X coordinate. P3 and P4 form a two byte value
that specifies the second Y coordinate. Any remaining parameters specify
additional coordinate values for additional markers, using the same format.
The printer uses the current values of color, mix, background mix, marker,
precision marker set, and marker symbol for drawing the marker.
This order updates the current graphics position to the value of the last point
coordinates. If this order does not specify any points, the current graphics
position will not change.
