Function Outline
Restrictions
The area enclosed by a line of the specified color is tiled with the specified tiling
pattern.
Up to 65535 of the following graphics can be registered on one screen. For
overlapping screens comprising 8 child screens, the maximum is 524,280
(65,535 8 screens).
Fixed display text, circles, arcs, sectors, polylines, polygons, rectangles, til-
ing, marks
There is no restriction on the number of graphics that can be registered for one
screen data file: any number can be registered as long as the data file capacity is
not exceeded.
The area to be tiled must be enclosed by a solid line of the same color. If the line
is broken at any point, or if it flashes or is deleted, the tiling pattern will cover the
area outside the line as well. Tiling will also spread outside the intended bound-
ary line, in accordance with the display order, if it is displayed before the border
line.
Depending on the combination of the foreground color of a graphic (when
tiled), the background color, and the border color, part of the frame of the
graphic may be invisible. This is a phenomenon peculiar to a color LCD, not a
failure of the PT. If this causes a problem, change the color combination.
