<h2><a name="color-editor-resources">Color Editor Resources</a></h2>
<p>You can set default values for all of the HSV and RGB
modification controls in the x <i>v color editor</i> window via X
resources. The easiest way to explain this is with an example.</p>
<ol>
<li>Start <i>xv</i> and put it in the background by typing '<tt>xv
&'</tt>.</li>
<li>Type the command '<tt>cat >foo'</tt> in an active <i>xterm</i>
window</li>
<li>Bring the <i>xv color editor</i> window up.</li>
<li>Issue the <b>Cut Resources</b> command.</li>
<li>Click your middle mouse button in the <i>xterm</i>
window. A set of resource lines describing the current
state of the <i>xv color editor</i> controls will be
'pasted' into the window. </li>
<li>You could type <b><ctrl-D></b> in the <i>xterm</i>
to complete the <i>cat</i> command, edit this file, and
put it in your <tt>.Xdefaults</tt> or <tt>.Xresources</tt>
file.</li>
</ol>
<p>The lines generated by Cut Resources will look like this:</p>
<blockquote>
<pre><font size="2">xv.default.huemap1: 330 30 CW 330 30 CW
xv.default.huemap2: 30 90 CW 30 90 CW

<p>These lines completely describe one state of the <i>xv color
editor</i> controls. There are five different states that you can
specify via X resources. The '<tt>default'</tt> state (as shown)
holds the settings used whenever the program is first started,
and whenever the <b>Reset</b> command is used. You can also store
settings in one of the four <i>xv</i> presets (accessed via the <b>1,
2, 3, </b>or <b>4</b> buttons in the <i>xv color editor</i>) by
changing the string '<tt>default'</tt> in the above lines to '<tt>preset1'</tt>,
'<tt>preset2'</tt>, '<tt>preset3'</tt>, or '<tt>preset4'</tt>
respectively.</p>
<p>There are four types of resource described in these lines: <tt>huemap</tt>
, <tt>whtmap</tt> , <tt>satval</tt> , and <tt>graf</tt> .</p>
<h3><a name="huemap-resources">Huemap Resources</a></h3>
<p>The <tt>huemap</tt> resources describe the state of the hue
remapping dials. There are six huemap resources per state of the <i>xv
color editor</i>. These huemap resources are numbered '<tt>huemap1'</tt>,
through '<tt>huemap6'</tt>, and correspond to the '<b>1'</b>-'<b>6</b>'
radio buttons under the hue remapping dials.</p>
<p>Each huemap resources takes six parameters:</p>
<ol>
<li>The 'starting' angle of the <i>From</i> range, in degrees
(integer).</li>
<li>The 'ending' angle of the <i>From</i> range, in degrees
(integer).</li>
<li>The direction of the <i>From</i> range. Either '<tt>cw'</tt>
(clockwise) or '<tt>ccw'</tt> (counter-clockwise).</li>
<li>The 'starting' angle of the <i>To</i> range, in degrees
(integer).</li>
<li>The 'ending' angle of the <i>To</i> range, in degrees
(integer).</li>
<li>The direction of the <i>To</i> range. Either '<tt>cw'</tt>
or '<tt>ccw'</tt>.</li>
</ol>
<h3><a name="whtmap-resources">Whtmap Resources</a></h3>
<p>The <tt>whtmap</tt> resource describes the state of the white
remapping control. There is one whtmap resource per state of the <i>xv
color editor</i> controls. The whtmap resource takes three
parameters:</p>
<ol>
<li>The hue to remap 'white' to, in degrees (integer).</li>
<li>The saturation to give to the remapped 'white', in
percent (integer).</li>
<li>A boolean specifying whether the white remapping control
is enabled. If '1', the control is enabled. If '0', the
control is disabled. </li>
</ol>
<h3><a name="satval-resource">Satval Resource</a></h3>
<p>The <tt>satval</tt> resource describes the value of the
Saturation dial. There is one satval resource per state. The
satval resource takes a single integer value, in the range 100,
which specifies how much to add or subtract to the overall image
color saturation.</p>
<h3><a name="graf-resources">Graf Resources</a></h3>
<p>The <tt>graf</tt> resources describe the state of the four
'graph' windows in the <i>xv color editor</i> window ( <i>Intensity</i>,
<i>Red</i>, <i>Green</i>, and <i>Blue</i>). The graf resources
can be in one of two formats, 'gamma' and 'spline/line'.</p>
<p>In 'gamma' format, the graf resource takes two parameters:</p>
<ol>
<li>The letter 'G', specifying 'gamma' mode</li>
<li>A single floating point number specifying the gamma
value.</li>
</ol>
<p>In 'spline/line' mode, the graf resource takes a variable
number of parameters:</p>
<ol>
<li>The letter 'S' specifying 'spline' mode, or the letter
'L' specifying 'line' mode.</li>
<li>An integer number indicating the number of handles
(control points) that this graph window will have. (Must
be in the range 2-16, inclusive.)</li>
<li>For each handle, there will be a ':', and the <i>x</i>
and <i>y</i> positions of the handle, separated by a
comma. The <i>x</i> and <i>y</i> positions can be in the
range 0-255 inclusive.</li>
</ol>

<h2>Window Classes</h2>
<p><i>xv</i> defines the following 'class' names for its various
top-level windows:</p>
<dl compact>
<dt><tt>XVroot</tt></dt>
<dd>for the <i>xv image</i> window</dd>
<dt> </dt>
<dt><tt>XVcontrols</tt></dt>
<dd>for the <i>xv controls</i> window</dd>
<dt> </dt>
<dt><tt>XVdir</tt></dt>
<dd><dl compact>
<dt>for the <i>xv load</i> and <i>xv save</i> windows</dt>
</dl>
</dd>
<dt><tt>XVinfo</tt></dt>
<dd><dl>
<dt>for the <i>xv info</i> window</dt>
</dl>
</dd>
<dt><tt>XVcedit</tt></dt>
<dd><dl compact>
<dt>for the <i>xv color editor</i> window</dt>
</dl>
</dd>
<dt><tt>XVps</tt></dt>
<dd><dl compact>
<dt>for the <i>xv postscript </i>window</dt>
</dl>
</dd>
<dt><tt>XVjpeg</tt></dt>
<dd><dl>
<dt>for the <i>xv jpeg</i> window</dt>
</dl>
</dd>
<dt><tt>XVtiff</tt></dt>

</dl>
</dd>
<dt><tt>XVconfirm</tt></dt>
<dd><dl>
<dt>for all the pop-up windows</dt>
</dl>
</dd>
</dl>
<p>You may be able to use these class names to do something nifty
with your window manager. For instance, with <i>mwm</i> you can
control which controls you'll get in the window frame, on a
per-window basis. For example, to turn off all the <i>mwm</i>
doodads that normally are tacked onto the <i>xv image</i> window,
you could put this in your .Xdefaults file:</p>
<blockquote>
<p><tt>Mwm*XVroot*clientDecoration: none</tt></p>
