White is - assumed to be the patch with the largest Y value.<br> - <br> - The <b>-N</b> flag causes the two sets of values to be normalized - to the XYZ of white for each set before comparison. White is assumed - to be the patch with the largest Y value.<br> - <br> - The <b>-D</b> flag causes the white reference point for the - conversion to L*a*b* to be D50 with a Y value of 100%. By default - the sample with the largest Y value is found, and the L*a*b* white - reference scaled to have that Y value. This allows sensible delta E - values when comparing absolute color values, such as those from - emission or display measurements.<br> - <br> - The <b>-c</b> option causes the differences between the test values - and the profile prediction of the color for each device value to be - displayed in CIE94 delta E, rather than plain L*a*b* delta E. CIE94 - delta E has a closer correspondence with perceived color differences - than the default CIE76 delta E values.<br> - <br> - The <b>-k</b> option causes the differences between the test values - and the profile prediction of the color for each device value to be - displayed in CIEDE2000 delta E, rather than plain L*a*b* delta E. - CIEDE2000 delta E has a closer correspondence with perceived color - differences than either CIE76 or CIE94 delta E values.<br> - <br> - If the <b>-s </b>flag is used in combination with the <b>-v</b> - flag, then the test point by test point output will be sorted from - worst to best.<br> - <br> - The <b>-w</b> creates a <a href="File_Formats.html#VRML">VRML</a> - 3D visualization of the differences between the test points in D50 - L*a*b* space, each difference being shown as a line vector. If the <span - style="font-weight: bold;">-W</span> flag is used, then the target - and measured values will also be marked by a small sphere. This can - be used to visualize the placement of values in a .ti3 (or other - CGATS file) by using the same file for both "target" and "measured" - values.<br> - <br> - The <b>-x</b> flag adds Lab axes to the VRML output.<br> - <br> - The <b>-f</b> flag enables Fluorescent Whitening Agent (FWA) - compensation. This only works if spectral data is available and, the - instrument is not UV filtered. FWA compensation adjusts the - spectral samples so that they appear to have been measured using an - illuminant that has a different level of Ultra Violet to the one the - instrument actually used in the measurement. The optional - illumination parameter allows specifying a standard or custom - illumination spectrum to be used as the similated instrument - illuminant, overriding the default <b>D50</b> or CIE computation - illuminant used for FWA (see <b>-i</b> below<b>). </b>See <a - href="colprof.html#f">colprof -f</a> for a fuller explanation. The - same value should be used as was used during the creation of the - profile.<br> - <br> - The <b>-i</b> flag allows specifying a standard or custom - illumination spectrum, applied to the spectral test point values to - compute CIE tristimulus values. <b>A</b>, <b>D50</b>, <b>D50M2, - 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. If FWA compensation is used during measurement, this - illuminant will be used by default as the simulated instrument - illuminant. The same value should be used as was used during the - creation of the profile.<br> - <br> - 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 same parameter value should be used as was used during the - creation of the profile.<br> - <br> - If both CIE and spectral values are present in the input files, the - CIE values will be used by default. Using the <span - style="font-weight: bold;">-i</span>, <span style="font-weight: - bold;">-o</span> or <span style="font-weight: bold;">-f</span> - flag will force spectral values to be used. The the <span - style="font-weight: bold;">-i</span>, <span style="font-weight: - bold;">-o</span> or <span style="font-weight: bold;">-f</span> - flags will apply to both the target and measured input files.<br> - <br> - <br> - <br> - <br> - <br> - <br> - </body> -</html> |
