<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>psscale</b>
plots gray scales or color scales on maps. Both horizontal
and vertical scales are supported. For cpt_files with
gradational colors (i.e., the lower and upper boundary of an
interval have different r/g/b values) <b>psscale</b> will
interpolate to give a continuous scale. Variations in
intensity due to shading/illumination may be displayed by
setting the option <b>−I</b>. Colors may be spaced
according to a linear scale, all be equal size, or by
providing a file with individual tile widths.</p>

<p style="margin-top: 1em" valign="top">Defines the
position of the center/top (for horizontal scale) or
center/left (for vertical scale) and the dimensions of the
scale. Give a negative length to reverse the scalebar.
Append <i>h</i> to get a horizontal scale [Default is
vertical].</p> </td>

tick, and gridline interval for the colorbar. The x-axis
label will plot beneath a horizontal bar (or vertically to
the right of a vertical bar), except when using
<b>−A</b>. As an option, use the y-axis label to plot
the data unit to the right of a horizontal bar (and above a
vertical bar). If <b>−B</b> is omitted, or no
annotation intervals are provided, the default is to
annotate every color level based on the numerical entries in
the cpt file (which may be overridden by ULB flags in the
cpt file). To specify custom text annotations for intervals,
you must append ;<i>annotation</i> to each z-slice in the
cpt file.</p></td>

changes are annotated. To use a subset, add an extra column
to the cpt-file with a L, U, or B to annotate Lower, Upper,
or Both color segment boundaries (but see <b>−B</b>).
If not given, <b>psscale</b> will read stdin. Like

any equal interval annotation set with <b>−B</b> will

discrete we will center each annotation on each rectangle,
using the lower boundary z-value for the annotation. If
<b>i</b> is prepended we annotate the interval range
instead. If <b>−I</b> is used then each rectangle will
have its constant color modified by the specified
intensity.</p> </td>

<h2>NOTES</h2>
<p style="margin-left:11%; margin-top: 1em">When the cpt
file is discrete and no illumination is specified, the color
bar will be painted using polygons. For all other cases we
must paint with an image. Some color printers may give
slightly different colors for the two methods given
identical RGB values.</p>
