Grids
The location of a form element on a page is specified in terms of its
horizontal and vertical displacement from the form origin. The units
of measurement used to define this displacement can be the
following:
•
Linear units—inches or centimeters
•
Dots—300 per inch
•
Xdots—600 per inch
•
Cpi and lpi—(characters per inch horizontally and lines per inch
vertically).
x and y coordinate
The y coordinate describes the vertical position on a grid. The x
coordinate describes the horizontal position. When both coordinates
are given together, the y coordinate is always specified first.
If you draw a horizontal and a vertical line through the form origin to
create x and y coordinates, you would express the location of the
form origin as y=0, x=0.
If you draw more lines to mark horizontal and vertical measurements
away from the form origin so that the lines were one unit of
measurement apart, you create a grid like the one shown in figure
2-9. You can then position form elements (lines, boxes, and so on)
by specifying a grid location.
Figure 2-9. Form grid
Example: You placed the letter “A” at location (2,1). If you are
measuring grid units in inches, the origin of the “A” character cell is
located two inches down and one inch to the right of the form origin.
