<h2>4. Sizes and Spacing
<a name="4. Sizes and Spacing"></a>
</h2>

Sizes are specified in inches.
If you don&rsquo;t like inches, it&rsquo;s possible to set a
global style variable scale that changes the unit.
Setting scale = 2.54 effectively changes the internal
unit to centimeters (all other size variable values are
scaled correspondingly).

<h3>4.1. Default Sizes of Objects
<a name="4.1. Default Sizes of Objects"></a>
</h3>

Here are the default sizes for
pic objects:

The simplest way to think about these defaults is that
they make the other basic objects fit snugly into a
default-sized box.

pic2plot(1) does not
necessarily emit a physical inch for each virtual inch in
its drawing coordinate system. Instead, it draws on a canvas
8&nbsp;virtual inches by 8&nbsp;virtual inches wide. If its
output page size is &ldquo;letter&rdquo;, these virtual
inches will map to real ones. Specifying a different page
size (such as, say, &ldquo;a4&rdquo;) will scale virtual
inches so they are output as one eighth of the page width.
Also, pic2plot(1) centers all images by default,
though the &minus;n option can be used to prevent
this.

<h3>4.2. Objects Do Not Stretch!
<a name="4.2. Objects Do Not Stretch!"></a>
</h3>

Text is rendered in the current
font with normal troff line spacing. Boxes, circles, and
ellipses do not automatically resize to fit enclosed
text. Thus, if you say box &quot;this text far too long
for a default box&quot; you&rsquo;ll get this:

Figure 4-1: Boxes
do not automatically resize

which is probably not the effect
you want.

<h3>4.3. Resizing Boxes
<a name="4.3. Resizing Boxes"></a>
</h3>

To change the box size, you can
specify a box width with the &ldquo;width&rdquo;
modifier:

Figure 4-2:
Result of box width 3

This modifier takes a dimension
in inches. There is also a &ldquo;height&rdquo; modifier
that changes a box&rsquo;s height. The width keyword
may be abbreviated to wid; the height keyword
to ht.

<h3>4.4. Resizing Other Object Types
<a name="4.4. Resizing Other Object Types"></a>
</h3>

To change the size of a circle,
give it a rad[ius] or diam[eter] modifier;
this changes the radius or diameter of the circle, according
to the numeric argument that follows.

Figure 4-3:
Circles with increasing radii

The move command can also
take a dimension, which just tells it how many inches to
move in the current direction.

Ellipses are sized to fit in the
rectangular box defined by their axes, and can be resized
with width and height like boxes.

You can also change the radius
of curvature of an arc with rad[ius] (which specifies
the radius of the circle of which the arc is a segment).
Larger values yield flatter arcs.

Figure 4-4:
arc rad with increasing radii

Observe that because an arc is
defined as a quarter circle, increasing the radius also
increases the size of the arc&rsquo;s bounding box.

<h3>4.5. The &lsquo;same&rsquo; Keyword
<a name="4.5. The &lsquo;same&rsquo; Keyword"></a>
</h3>

In place of a dimension
specification, you can use the keyword same. This
gives the object the same size as the previous one of its
type. As an example, the program

.PS 
box; box wid 1 ht 1; box same; box 
.PE

gives you

same keyword
