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> <br> <br> <br> <br> </body> </html>
