<h3>Usage Details and Discussion</h3>
|
|
This is an analogous tool to <a href="colprof.html">colprof</a>,
|
|
but applying to
|
|
<a href="File_Formats.html#MPP">MPP</a> profiles, rather than <a
|
|
href="File_Formats.html#ICC">ICC</a> profiles. This tool creates an
|
|
MPP profile given the <a href="File_Formats.html#.ti3">.ti3</a> test
|
|
chart information. The model based device profile is an Argyll specific
|
|
format, used to hold the parameters to a general model based device
|
|
characterization.
|
|
This is a less precise and general format than and ICC profile, but is
|
|
a compact way of representing a devices response when it has a large
|
|
number
|
|
of color channels, or when very few measured data points are available
|
|
for its construction.<br>
|
|
<br>
|
|
The <b>-v</b> flag causes extra information to be printed as the
|
|
profile is being created, including the delta E statistics for the test
|
|
data fit against the profile.<br>
|
|
<br>
|
|
The <b>-q</b> parameter sets the level of effort and hence quality in
|
|
the resulting profile. Different quality profile use different numbers
|
|
of
|
|
model parameters.<br>
|
|
<b>s </b>simple - use a close
|
|
variation
|
|
of the Neugenbauer model, with a single parameter, per device
|
|
linearisation curve.<br>
|
|
<b>l</b> low quality
|
|
profiles
|
|
have more detail terms to account for device linearisation.<br>
|
|
<b>m</b> medium quality profiles, add
|
|
color channel cross mixing terms, as well as using more detail
|
|
parameters.<br>
|
|
<b>h</b> high quality profiles,
|
|
use more detail terms and more profile refinement iterations.<br>
|
|
<br>
|
|
The <b>-l</b> flag overrides any default ink limit (Total Area
|
|
Coverage) recorded in the .ti3 file.<br>
|
|
<br>
|
|
The <b>-s</b> flag enables the creation of spectral model values, as
|
|
well as the tri-stimulus model.<br>
|
|
<br>
|
|
The <b>-m</b> flag is currently not implemented.<br>
|
|
<br>
|
|
The <b>-y</b> flag causes each test value and its error to be printed.<br>
|
|
<br>
|
|
The <b>-L</b> flag causes the CGATS output file to contain D50 L*a*b*
|
|
parameters rather than XYZ.<br>
|
|
<br>
|
|
The <i>inoutfile</i> parameters should be the base name of the .ti3
|
|
file, and mppprof will output an mpp that has the same basename and the
|
|
.mpp extension.<br>
