+ <h3>Summary&nbsp;<br>
+ </h3>
+ Lookup individual color values forward or inverted though an ICC
+ profile table or CAL file. <b>xicclu</b> is the analogue of the
+ icclib tool <a href="icclu.html">icclu</a>, but expands the
+ capability to reverse lookup the Lut tables, and displaying PCS
+ values in CIECAM02 Jab space. <b>xicclu</b> can also be used to
+ plot the device value composition down the neutral axis for device
+ profiles, or CAL file contents.<br>
+ <br>
+ Few of the options that apply to ICC profiles apply to CAL files,
+ although device value options such as <b>-e</b> or <b>-E</b> will
+ work. To lookup inverted CAL values, use <b>-f b</b>.<br>

-<h3>Flags and Parameters</h3>
-<a name="v"></a> The <b>-v</b> parameter sets the level of verbosity.
-Default is level 1, which repeats each input value, the colorspaces of
-input and output, the type of conversion algorithm used, and if the
-result was clipped. Level 2 adds prints extra information about the
-profile before doing the conversions. Level 0 turns off all verbosity,
-just outputting the results of each conversion. Use the latter to
-capture batch output ready for further processing.<br>
-<br>
-<a name="g"></a>The <b>-g</b> flag causes a plot of the device values
-along a slice through the Lab or Jab colorspace, rather than allowing
-the interactive looking up of color
-values. By default this will be the neutral axis
-from the white point to the black point, but the start and end can be
-overridden using the <span style="font-weight: bold;">-G</span>
-parameters.
-This is useful in determining the existing black generation in a CMYK
-profile,
-or exploring the behavior of various black generation options using
-the
-<b>-k</b> parameters. The profile must be a device profile, and the PCS
-must
-be either Lab or Jab. The default plot is up the neutral axis is from
-the white to
-the black point (scale 0 to 100%), and shows the percentage of each
-device colorant. To examine a profiles B2A table black
-generation,
-use the flag <b>-fb</b> to select the B2A table, or to invert the A2B
-table,
-and be able to explore black generation behavior, use the <b>-fif</b>
-flag.
-The appropriate intent can be selected with the <b>-i</b> flag,
-&nbsp;as
-can other flags appropriate to the function selected.&nbsp; See <a
- href="#xg">example</a>.<br>
-<br>
-<a name="Gs"></a>The <span style="font-weight: bold;">-G </span><small><span
- style="font-family: monospace;"><span style="font-weight: bold;">s:L:a:b</span></span></small>
-parameter overrides the plot slice start point of white, with some
-other point specified in Lab or Jab Profile Connection Space. The
-parameter must be a single string that combines<span
- style="font-weight: bold;"> s:</span> with the three numbers separated
-by the '<span style="font-weight: bold;">:'</span> character (no
-spaces).<br>
-<br>
-<a name="Ge"></a>The <span style="font-weight: bold;">-G </span><small><span
- style="font-family: monospace;"><span style="font-weight: bold;">e:L:a:b</span></span></small>
-parameter overrides the plot slice end point of black, with some
-other point specified in Lab or Jab Profile Connection Space. The
-parameter must be a single string that combines<span
- style="font-weight: bold;"> s:</span> with the three numbers separated
-by the '<span style="font-weight: bold;">:'</span> character (no
-spaces).<br>
-<br>
-<a name="f"></a> The <b>-f</b> flag selects which type of table or
-conversion is to be used. In addition to the usual four tables that can
-be accessed in a fully populated Lut based profile, two additional
-options are available in <b>xicclu</b>. One is to invert the forward
-table, and the other is to invert the backward table. For non Lut based
-profiles, -fif is equivalent to -fb, and -fib is equivalent to -ff.
-Note that the -fib combination may not be fully supported.<br>
-<br>
-<a name="i"></a> The <b>-i</b> flag selects the intent table used for
-a lut based
-profile. It also selects between relative and absolute colorimetric for
-non-lut base profiles.<br>
-<br>
-<a name="o"></a> A profile is allowed to contain more than the minimum
-number of elements or table needed to describe a certain transform, and
-may contain redundant descriptions. &nbsp;By default, Lut based table
-information will be used first if present, followed by matrix/shaper
-information, and only using monochrome information if it is all that is
-present. The <b>-o</b> flag, reverses this order.&nbsp;&nbsp;&nbsp; <br>
-<br>
-<a name="p"></a> Normally the native PCS (Profile Connection Space) of
-a device or abstract profile is used, but the <b>-p</b> flag allows
-this to be overridden: <span style="font-weight: bold;">-px</span>:
-XYZ (scaled to 1.0), <span style="font-weight: bold;">-pX</span>: XYZ
-scaled to 100, <span style="font-weight: bold;">-pl</span>: L*a*b*, <span
- style="font-weight: bold;">-pL</span>: LCh, <span
- style="font-weight: bold;">-py</span>: Yxy space, <span
- style="font-weight: bold;">-pj</span>: CIECAM02 appearance space Jab,
-or <span style="font-weight: bold;">-pJ</span>: CIECAM02 appearance
-space JCh.<span style="font-weight: bold;"><br>
-</span>Note that the CIECAM02 output space selection by default uses
-the colorimetric table of the profile, but that the perceptual or
-saturation tables may be used by selecting them using the <span
- style="font-weight: bold;">-i</span> parameter. If the absolute
-colorimetric intent is chosen using <span style="font-weight: bold;">-ia</span>
-in combinations with <span style="font-weight: bold;">-pj</span>,
-then&nbsp; Jab with
-a fixed white reference is used, which emulates an absolute CIECAM02
-Jab
-appearance space. <br>
-<br>
-<a name="s"></a> Usually device values are processed and displayed
-using a normalized value range between 0.0 and 1.0 Sometimes other
-systems scale them to some other range (such as 100 or 255) due to an
-underlying binary representation. The <span style="font-weight: bold;">-s</span>
-flag lets you input and display such data in its normal range. For
-instance, if your device values have a range between 0 and 255, use <span
- style="font-weight: bold;">-s 255.</span><br>
-<br>
-<a name="k"></a> When inverting a CMYK profile, (ie. using the -fif
-flag), an input PCS value can have many possible CMYK solutions. To be
-able to return a unique solution, a black level (or black inking rule)
-should be chosen. The choice here reflect similar choices in black
-generation available in other tools (eg. <a href="colprof.html">colprof</a>,
-<a href="collink.html"> collink</a>), with the addition of two extra
-options.<br>
-<br>
-&nbsp;Possible arguments to the <b>-k</b> option are:<br>
-<br>
-<b> -kz</b> selects minimum black (0.0)<br>
-<b> -kh</b> selects a black value of 0.5<br>
-<b> -kx</b> selects the maximum possible black (1.0)<br>
-<b> -kr</b> selects a linear black ramp, starting at minimum black for
-highlight, and maximum black for shadow (equivalent to -kp 0 0 1 1 1).
-This is the default.<br>
-<b> -kl</b> uses an extra (fourth) value entered after the input PCS
-value, to select a black locus target between 0.0 and 1.0.<br>
-<b> -kv</b> uses an extra (fourth) value entered after the input PCS
-value, to select a black value target value between 0.0 and 1.0.<br>
-<br>
-<b><a name="kp"></a>-k p stle stpo enpo enle shape</b>&nbsp; allows an
-arbitrary black value ramp to be defined, consisting of a starting
-value (stle) for highlights, a breakpoint L value (stpo) where it
-starts to transition to the shadow level, an end breakpoint L (enpo)
-where it flattens out again, and the finishing black level (enle) for
-the shadows. There is also a curve parameter, that modifies the
-transition from stle to enle to either be concave (ie.&nbsp; the
-transition starts gradually and and finished more abruptly) using
-values 0.0-1.0, with 0.0 being most concave, or convex (the transition
-starts more abruptly but finishes gradually), using values 1.0-2.0,
-with 2.0 being the most convex.<br>
-<br>
-Typical black value generation curve with parameters something
-like: -kp 0 .05 1 .9 .8<br>

+ <a name="k"></a> When inverting a CMYK profile, (ie. using the -fif
+ flag), an input PCS value can have many possible CMYK solutions. To
+ be able to return a unique solution, a black level (or black inking
+ rule) should be chosen. The choice here reflect similar choices in
+ black generation available in other tools (eg. <a
+ href="colprof.html">colprof</a>, <a href="collink.html"> collink</a>),
+
+
+
+
+ with the addition of two extra options.<br>
+ <br>
+ &nbsp;Possible arguments to the <b>-k</b> option are:<br>
+ <br>
+ <b> -kz</b> selects minimum black (0.0)<br>
+ <b> -kh</b> selects a black value of 0.5<br>
+ <b> -kx</b> selects the maximum possible black (1.0)<br>
+ <b> -kr</b> selects a linear black ramp, starting at minimum black
+ for highlight, and maximum black for shadow (equivalent to -kp 0 0 1
+ 1 1). This is the default.<br>
+ <b> -kl</b> uses an extra (fourth) value entered after the input PCS
+ value, to select a black locus target between 0.0 and 1.0.<br>
+ <b> -kv</b> uses an extra (fourth) value entered after the input PCS
+ value, to select a black value target value between 0.0 and 1.0.<br>
+ <br>
+ <b><a name="kp"></a>-k p stle stpo enpo enle shape</b>&nbsp; allows
+ an arbitrary black value ramp to be defined, consisting of a
+ starting value (stle) for highlights, a breakpoint L value (stpo)
+ where it starts to transition to the shadow level, an end breakpoint
+ L (enpo) where it flattens out again, and the finishing black level
+ (enle) for the shadows. There is also a curve parameter, that
+ modifies the transition from stle to enle to either be concave
+ (ie.&nbsp; the transition starts gradually and and finished more
+ abruptly) using values 0.0-1.0, with 0.0 being most concave, or
+ convex (the transition starts more abruptly but finishes gradually),
+ using values 1.0-2.0, with 2.0 being the most convex.<br>
+ <br>
+ Typical black value generation curve with parameters something like:
+ -kp 0 .05 1 .9 .8<br>

-Any of the <span style="font-weight: bold;">-k</span> options above
-can use the <span style="font-weight: bold;">-K</span> version, in
-which rather than a black value target being defined by the inking
-rule, a black <span style="text-decoration: underline;">locus</span>
-target is defined. For each lookup, the minimum possible black level
-and the maximum possible black level is determined, the former
-corresponding to a locus target of 0, and the latter corresponding to a
-locus target of 1. For instance, at
-the
-white point, no black will be used in the output, even if the black
-locus specifies a maximum (since the maximum amount of black that
-can be used to print white is actually zero). Similarly, at the black
-point, black may well be used, even if the black locus specifies
-zero black (since a certain amount of black is needed to achieve the
-desired density of color). <br>
-<tt> </tt><span style="text-decoration: underline;"></span><br>
-&nbsp;The <b>-g</b> flag can be used together with the <b>-fif</b>
-flag, to plot

-or <span style="font-weight: bold;">-K </span>parameter
-values.<br>
-<br>
-<b><a name="l"></a>-l</b> <i>tlimit</i>&nbsp; &nbsp;&nbsp; Sets the
-total ink limit (TAC, Total Area Coverage) for the CMYK inverse forward
-lookup, as a total percentage from 0% to 400%. If none is provided, it

-<br>
-<b><a name="L"></a>-L</b> <i>klimit</i>&nbsp; &nbsp; Sets the black

-<br>
-<a name="a"></a> If the <b>-a</b> flag is used for inverse forward

-the target PCS value cannot be reproduced by the device (ie. it clips),
-then the achievable, clipped PCS value is displayed.<br>
-<br>
-<a name="b"></a> If the <b>-b</b> flag is used for inverse forward

-Jab appearance colorspace, rather than L*a*b* colorspace.<br>
-<br>
-<a name="m"></a> The <b>-m</b> flag turns on an internal processing

-<br>
-<a name="c"></a>Whenever PCS values are to be specified or displayed in

-specified in two basic ways. One
-is to select from the list of "pre canned", enumerated viewing
-conditions, choosing one that is closest to the conditions that are
-appropriate for the media type and situation. Alternatively, the
-viewing conditions parameters can be specified in detail individually.
-If both methods are used, them the chosen enumerated condition will be

-<a name="p1"></a> The final parameter is the name of the <a

-<h3>Usage and Discussion</h3>
-Typical usage for an output profile might be:<br>
-<br>
-&nbsp;&nbsp;&nbsp; xicclu -ff -ip profile.icm<br>
-<br>
-Normally the program is interactive, allowing the user to type in input
-color
-values, each number separated by a space, and the resulting output
-color
-being looked up and displayed after pressing return. To batch process
-a
-group of color values, prepare a text file containing each input value
-on
-a
-separate line, and use the input indirection facilities of your command
-line
-shell to redirect this input file into the standard input of xicclu.
-The
-output can be captured to a file by redirecting standard output to a
-file.
-In most shells this would be done something like this:<br>
-<br>
-&nbsp;&nbsp;&nbsp; xicclu -ff -ip profile.icm &lt; inputvalues.txt &gt;
-outputvalues.txt<br>
-<br>
-<a name="xg"></a>When plotting the neutral axis behavior, plotting the

-behavior would typically be done something like this:<br>
-<br>
-&nbsp;&nbsp;&nbsp; xicclu -g -fb profile.icm<br>
-<br>
-Exploring possible black generation and ink limiting behavior might be
-done
-like this:<br>
-<br>
-&nbsp;&nbsp;&nbsp; xicclu -g -fif -kp 0 .1 .9 1 .5 -l230 -L95
