USING HFDL COMMANDS
Parameters
HORIZONTAL or VERTICAL specifies the direction of the text
relative to the page orientation.
SPACED defines the amount of vertical space (in n units ) a line
of text occupies. If you specify a value (not zero), it replaces the
line spacing value of the font being used for this TEXT AT
command. An LPI value specifies line height in terms of lines
per inch. All other specifications are actual line height
measurements. The n units value must be positive. The units are
INCHES, CENTIMETERS, CPI, LPI, DOTS, and XDOTS. You can
use two decimal places when you specify inches and centimeters.
You must express DOTS and XDOTS in integers. POINTS
specifies that you want the TEXT SPACED in n POINTS (1/72
inch).
ALIGNED specifies the text justification alignment (LEFT, RIGHT,
CENTER, TOP, BOTTOM, JUSTIFIED). See the Xerox Laser
Printing Systems Forms Creation Guide for alignment examples.
You can center multiple horizontal strings beneath each other or
right– or left–justify them. You can center multiple vertical
strings alongside each other or align them on the top or bottom.
The JUSTIFIED alignment mode allows you to justify text. In
simple justification (with no COLUMN), you must specify where
the lines break. You can justify lines by finding the longest line
in a block of lines, then justify other text strings to this length.
This method of justification is best for justifying small blocks of
text or when you must justify the last line of a paragraph. You
can use the JUSTIFIED parameter with the INTERWORD SPACE
and the COLUMN SIZE IS commands. In this mode, text begins
at the coordinates you specify and extends to the right column
boundary. Line breaks occur automatically. Enter text in one
continuous string without line breaks.
Example
JUSTIFIED parameters:
TEXT JUSTIFIED AT 1,1 'This is a sample'
'of justified text' 'in block format.';
This produces the following text on the form:
This is a sample
of justified text
in block format.
You specify IN COLUMN for any alignment mode and use it with
the COLUMN SIZE IS command. Line breaks occur automatically
when you use TEXT ALIGNED IN COLUMN or TEXT JUSTIFIED
IN COLUMN. You can enter a complete paragraph of text in
one continuous string. A quote indicates the end of a paragraph
rather than a line break. The system ignores multiple line breaks.
Columns do not have a fixed location on the page. You place
them relative to the TEXT command you specify. The horizontal
coordinate you specify sets the left column boundary. You set
the right column boundary to the sum of the column width and
the left column boundary.
You can include a maximum of 4096 characters in one
continuous text string.
