Sections
To duplicate identical information on a page, create sections.
However, form image buffer limitations and potential line density
problems should be taken into account whenever this feature is used.
A form comprised of many sections often takes up more space in the
form image buffer than a form created without sections. This occurs
because a single long line requires less buffer space than numerous
short lines. When you create a form by invoking defined sections,
there is a tendency to begin and end lines at section boundaries,
even when they are continuous through a series of sections. This is
a much less efficient form creation technique than taking the long
lines out of the sections and drawing them as continuous lines.
A less obvious inefficiency of using the form image buffer may occur
when there is a line that switches from solid to dotted and vice versa.
The common method of creating this type of line is to draw short
segments of solid and dotted lines. (This is inefficient use of the form
image buffer even if a SOLID 0 line is drawn first. A SOLID 0 line is
useful in saving space in the line tables but cannot help save buffer
space.)
The efficient approach to saving form image buffer space is to draw
a continuous dotted line and to overlay a series of short, solid line
segments. However, while this technique makes best use of the form
image buffer space, it does not reduce the load on the imaging
section of the system. (Refer to the “Scan line density” section in this
chapter.) In a form where there is a problem with exceeding both form
image buffer and line density restrictions, you may have to use logos
or a specialty form font.
