<h3>Usage Details and Discussion</h3>
This is an analogous tool to <a href="icclu.html"> icclu </a>, but
applying
to <a href="File_Formats.html#MPP">MPP</a> profile, rather than <a
href="File_Formats.html#ICC">ICC</a> profiles. Because MPP profiles
can also contain a spectral description of device behavior, there are
extra options in mpplu to describe how to convert spectral values into
CIE tristimulus values.<br>
Some additional functionality is included in mpplu, analogous to <a
href="iccgamut.html"> iccgamut</a>, allowing gamut files and images to
be generated from MPP profiles.<br>
<br>
The <b>-v</b> flag causes extra information about the profile to be
printed.<br>
<br>
The <b>-f</b> flag is experimental, and should be ignored.<br>
<br>
Normally L*a*b* is displayed, but this can be changed using the the <b>-p</b>
flag and XYZ, Yxy, or spectral values to be be displayed.<br>
<br>
If an illuminant, observer or Fluorescent Whitening Agent compensation
is selected, then the CIE tristimulus values will be computed from the
spectral information in the MPP profile (if present).<br>
<br>
The <b>-l</b> flag overrides any default ink limit (Total Area
Coverage) recorded in the profile. The ink limit has an effect on the
results of a gamut
generated from the profile.<br>
<br>
The <b>-i</b> flag allows specifying a standard or custom illumination
spectrum, applied to reflective spectral profile data to compute CIE
tristimulus
values. <b>A</b>, <b>D50</b>, <b>D65</b>, <b>F5</b>, <b>F8</b>, <b>F10</b>
are a selection of standard illuminant spectrums, with <b>D50</b>
being the
default. If a filename is specified instead, it will be assumed to be
an
Argyll specific <a href="File_Formats.html#.sp">.sp</a> spectrum file.<br>
<br>
<a name="o"></a> The <b>-o</b> flag allows specifying a tristimulus
observer, and is used to compute PCS (Profile Connection Space)
tristimulus values. The following choices are available:<br>
<b> 1931_2</b> selects the standard CIE 1931 2 degree observer.
The default.<br>
<b>1964_10</b> selects the standard CIE 1964 10 degree observer.<br>
<b>1955_2</b> selects the Stiles and Birch 1955 2 degree
observer<br>
<b>1978_2 </b>selects the Judd and Voss 1978 2 degree observer<br>
<b>shaw</b> selects the Shaw and Fairchild 1997 2 degree
observer<br>
<br>
The <b>-u</b> flag enables Fluorescent Whitening Agent compensation,
which compensates for the effect a different illuminant will have, on
any Fluorescent Whitening Agent present in the reflective media.<br>
<br>
The <b>-g</b> flag causes mpplu to simply generate a gamut surface
description from the profile, creating a <a
href="File_Formats.html#.gam">.gam</a> file with the same base name as
the given profile.<br>
<br>
The <b>-w</b> flag causes the gamut surface to be generated in <a
href="File_Formats.html#X3DOM">X3DOM</a> format
as well as <a href="File_Formats.html#.gam">.gam</a> format.<br>
<br>
<small><span style="font-family: monospace;">The <span
style="font-weight: bold;">-n</span> flag suppresses the X3DOM axes.<br>
<br>
The <span style="font-weight: bold;">-a</span> <span
style="font-weight: bold;">n</span> parameter sets a transparency
level in the X3DOM surface.</span></small><br>
<br>
The <b>-d</b> parameter controls the level of detail displayed in the
gamut surface. The parameter roughly corresponds to a deltaE value, so
smaller values give greater detail. The default value is around 10, and
is a good place to start. Small values may take a lot of time to
generate, and will produce big files.<br>
<br>
The <b>-t</b> parameter invokes special MPP test and diagnostic output.<br>
