PLANNING YOUR FORMS
Form element Element origin
Fixed text (single line) Upper–left corner of the first
character cell when the line appears
upright.
Fixed text Upper edge of the topmost character
(multiple lines) cell and the leftmost edge of the
leftmost character cell when viewed
in an upright position.
Graphics Upper–left corner of the image.
Logos and signatures Upper–left corner of the first
character cell.
Sections (of a form) Upper–left corner of the section.
Grids
You specify the location of a form element (alphanumeric
character, line, or box) on a page in terms of its horizontal and
vertical displacement from the form origin. You can use these
units of measure to define this displacement:
• Characters per inch (cpi) horizontally
• Dots per inch (300 dpi)
• Linear units (inches or centimeters)
• Lines per inch (lpi) vertically
• Xdots (600 dpi).
X and Y coordinates
If you draw a horizontal and vertical line through the form origin
to create
x
and
y
coordinates, the location of the form origin is
expressed as
y
=0,
x
=0. When specifying both coordinates,
provide the
y
value first. Figure 2–4 shows the correct placement
for
x
and
y
coordinates.
