-<h3>Usage Details and Discussion</h3>
-<b>invprofcheck</b> provides a way of checking how well an&nbsp;<a
- href="File_Formats.html#ICC">ICC</a> profile inverse transform inverts
-the forward transform. For devices with more than 4 channels, a total
-ink limit is assumed, and (if no <span style="font-weight: bold;">-l</span>
-parameter is given) a reasonable number is deduced from the reverse
-table. A grid of device values is created, and the transform from
-PCS-&gt;device, and then device-&gt;PCS is computed in L*a*b* space.
-The average, maximum and RMS error delta E values are computed and
-displayed in the chosen delta E metric. A <a
- href="File_Formats.html#X3DOM">X3DOM</a> plot of the error vectors can
-be created. <span style="font-weight: bold;">invprofcheck</span> tries
-to only test in-gamut color values. Note that because it scans a device
-grid, for a CMYK device, the density of test points will be
-progressively higher in the dark regions, and the average and RMS
-values will be distorted by the denser sampling.<br>
-<br>
-The <b>-v</b> flag prints out extra information during the checking. A
-value greater than 1 will print the color values of each test point.<br>
-<br>
-The <b>-l</b> flag allows setting a total ink limit (TAC) for printing
-devices. If a device has a total ink limit, and hasn't been
-characterised with device values above this limit, then plotting the
-gamut in these areas will almost certainly be misleading. The ink limit
-will be in final calibrated device values if the profile includes
-calibration information.<br>
-<br>
-The <b>-L</b> flag allows setting a black channel ink limit for
-printing
-devices. If a device has a black ink limit, and hasn't been
-characterised with device values above this limit, then plotting the
-gamut in these areas will almost certainly be misleading. The black ink
-limit
-will be final calibrated device values if the profile
-includes calibration information.<br>
-<br>
-The default device grid is relativy low, and 11 (ie. 11 x 11 x 11 for
-an RGB device, 11 x 11 x 11 x 11 for a CMYK device etc.).<br>
-<br>
-The <span style="font-weight: bold;">-h</span> flag selects a higher
-device grid resolution of 27.<br>
-<br>
-The <span style="font-weight: bold;">-u</span> flag selects an
-extremely high device grid resolution of 61. This will probably take a
-long time to run.<br>
-<br>
-The <span style="font-weight: bold;">-G res</span> option allows a
-specific grid resolution to be used.<br>
-<br>
-The <b>-c</b> option causes the error differences 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 error differences 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>
-The <b>-w</b> creates a <a href="File_Formats.html#X3DOM">X3DOM</a> 3D
-visualization
-of the differences between the test points and the profiles prediction
-of
-the resulting colors.<br>
-<br>
-The <b>-x</b> flag adds Lab axes to the X3DOM output.<br>
-<br>
-The <span style="font-weight: bold;">-e</span> flag causes the error
-vectors in the X3DOM output to be color coded according to their
-lengths, from longest to shortest: yellow, red, magenta, blue, cyan and
-green.<br>
