# SetBounds(
   x:LeftEdge,
   y:TopEdge | b:TopBaseline,
   w:Width,
   h:Height
)

Parameter	Option	Description
x	optional	The left edge of the bounding box. Any of the positioning methods may be used.
y	optional, or b	The top edge of the bounding box, or if you prefer you may use b instead. Any of the positioning methods may be used.
b	optional, or y	The top baseline of the bounding box based on the current font. May be used instead of y. Any of the positioning methods may be used.
w	optional	The width of the bounding box.
h	optional	The height of the bounding box.

Description

By default, the HMI bounding box is the whole screen. However if you wish to limit text to a smaller region of the screen, then use a bounding box to set those limits.

Any parameters that are no specified will remain unchanged.

Use "b" when you want to line up the top of the bounding box with a line of text. More information on baseline can be found in SetFont().
