Rectangle Fields

– Field Type 2

Rectangle Fields are used to display a rectangle that can be either open or filled. A rectangle can be used as
a vertical or horizontal line. The rectangle is drawn between Coordinate A and Coordinate B where
Coordinate A must be the top-left corner and Coordinate B must be the bottom-right corner of the rectangle.
No rectangle will be drawn if the coordinates are not specified in the correct order.

A rectangle may be drawn with either one or two regions depending on the parameters of the Graphic Field.
The Line region is located around the perimeter of the rectangle and is drawn with the line color (as specified
by the GnnRrrr, GnnGggg, GnnBbbb, and GnnAaaa commands). The Line region has a width in pixels that
is specified in the width parameters of the Graphic Field. The default line width is 1pixel. If the line width is
large, the entire interior of the rectangle may be part of the Line region. If the line width is narrow the interior
of the rectangle contains a Fill region.

The  command  GnnWwwww  set  the  line  width  to  the  same  value  for  both  the  vertical  and  horizontal  lines,
and  the  command  GnnWxxxx,yyyy  sets  the  horizontal  line  widths  (xxxx)  and  vertical  widths  (yyyy)
independently.  When the Width parameter is set to 0 in the above commands, or when the Width is greater
than half the size of the rectangle, the entire rectangle is drawn with the line color. The line width can also be
set for each side of the rectangle individually. The commands GnnWLwwww, GnnWRwwww, GnnWTwwww,
and  GnnWBwwww  set  the  width  of  the  left,  right,  top  and  bottom  sides  of  the  rectangle  respectively.  A
parameter  value  of  zero  has  a  different  meaning  for  these  commands  than  it  does  for  the  previous
commands.  When  used  with  these  four  commands,  the  width  value  zero  0  prevents  that  side  of  the
rectangle from being drawn.

The Fill color parameters are set by the GnnBRrrr, GnnBGggg, GnnBBbbb, and GnnBAaaa commands. By
default, the Fill region is the entire interior of the rectangle that is not drawn  in the Line color, but  it is also
possible to limit the fill to a specified width around the interior of the line. Each side of the rectangle has a fill
width  associated  with  it.  The  command  GnnFXwwww  sets  the  Fill  width  in  pixels  inside  the  left  and  right
sides of the rectangle, and, GnnFYwwww sets the fill width inside the top and bottom sides of the rectangle.

The commands  GnnFLwwww, GnnFRwwww, GnnFTwwww, and GnnFBwwww  set the fill  width for the left,
right,  top,  and  bottom  sides  individually.  Any  pixel  that  is  within  the  fill  width  for  one  or  more  sides  of  the
rectangle  is  part  of  the  Fill  region. The  default  fill  width for  the  left  side  is  9999,  causing  the  left  side  fill  to
extend throughout the entire interior of any rectangle. The default fill width for the right, top and bottom sides
is 10 pixels.

When a fill region exists, it may either be drawn with the background color, or else the pixels can be left
undrawn. The command GnnBD0 prevents the fill from being drawn, and the command GnnBD1 draws the
