    <h2><b>spectro/ccxxmake</b></h2>
    <h3>Summary</h3>
    For Colorimeters that rely on a calibration matrix, <span
      style="font-weight: bold;">ccxxmake</span> allows creation of a
    correction matrix file (<a href="File_Formats.html#.ccmx">ccmx</a>)
    for a particular <span style="font-weight: bold;">Colorimeter &amp;
      Display</span> combination, by making use a reference <span
      style="font-weight: bold;">Spectrometer</span> or Colorimeter
    instrument. This can then be used to improve the accuracy of
    subsequent measurements with that Colorimeter on that Display by
    using it with the <a href="dispcal.html#X">dispcal</a>, <a
      href="dispread.html#X">dispread</a> and <a href="spotread.html#X">spotread</a>
    -X option. A ccmx file can also be <a href="oeminst.html">installed</a>,
    and will then appear in the available display type selection (<b>-y</b>
    option). See <a href="WideGamutColmters.html">Wide Gamut Displays
      and Colorimeters</a> for more information on why this may be
    useful. [ <span style="font-weight: bold;">Note</span> that to make
    use of a <u>colorimeter</u> as a CCMX reference, you will have to
    provide two .ti3 files rather than using interactive measurement-
    see <a href="#f"><span style="font-weight: bold;">-f</span></a>. ]<br>
    <br>
    For Colorimeters that have sensor spectral sensitivity calibration
    information built into them&nbsp; (ie. the X-Rite <span
      style="font-weight: bold;">i1d3</span>, and<span
      style="font-weight: bold;"><span style="font-weight: bold;"></span></span>
    DataColor <span style="font-weight: bold;">Spyder4 &amp; Spyder5</span>),

    <span style="font-weight: bold;">ccxxmake</span> allows a creation
    of a calibration spectral sample (<a href="File_Formats.html#.ccss">ccss</a>)
    for a particular <span style="font-weight: bold;">Display</span>,
    by making use a reference <span style="font-weight: bold;">Spectrometer</span>
    instrument. This can then be used to improve the accuracy of
    subsequent measurements on that Display using such Colorimeters, by
    using it with the <a href="dispcal.html#X">dispcal</a>, <a
      href="dispread.html#X">dispread</a> and <a href="spotread.html#X">spotread</a>
    -X option, or it can be <a href="oeminst.html">installed</a>, and
    will then appear in the available display type selection (<b>-y</b>
    option).<br>
    <br>
    The instrument manufacturer may supply spectral sample files (see <a
      href="oeminst.html">oeminst</a>).<br>
    <br>
    There is a <a href="ccmxs.html">list of contributed</a> <span
      style="font-weight: bold;">ccmx</span> (Colorimeter Correction
    Matrix) files.<br>

    <h3>Usage Details and Discussion</h3>
    <a name="v"></a>The <b>-v</b> flag causes extra information to be
    printed out during chartread operation.<br>
    <br>
    <a name="S"></a><span style="font-weight: bold;">-S</span> By
    default a Colorimeter Correction Matrix (<span style="font-weight:
      bold;">CCMX</span>) will be created from both <span
      style="font-weight: bold;">Colorimeter</span> and <span
      style="font-weight: bold;">Spectrometer</span> readings, which
    allows correction for errors with a particular Colorimeter and
    Display combination. If the <span style="font-weight: bold;">-S</span>
    flag is used, then instead a Colorimeter Calibration Spectral Set (<span
      style="font-weight: bold;">CCSS</span>) file is created from just
    the <span style="font-weight: bold;">Spectrometer</span> readings,
    that allows calibrating any suitable Colorimeter to the Display.<br>
    <br>
    <a name="f"></a><span style="font-weight: bold;">-f <span
        style="font-style: italic;">ref.ti3[,targ.ti3]</span></span> By
    <span style="text-decoration: underline;">default</span> <span
      style="font-weight: bold;">ccxxmake</span> creates a <span
      style="font-weight: bold;">CCMX</span> file by displaying test
    patches on the screen, and then prompting you to measure them
    interactively with the two instruments. An alternative is to create
    a small number of test values using <span style="font-weight:
      bold;">targen</span> suitable for display profiling (or use the <span
      style="font-weight: bold;">ref/ccxx.ti1</span> file provided with
    ArgyllCMS), and then measure them with the two instruments using <span
      style="font-weight: bold;">dispread</span> to create a reference
    and target .ti3 files, and then provide the two files as arguments
    to <span style="font-weight: bold;">ccxxmake -f</span>. Normally
    the reference file will be created using a spectral instrument and
    you will want to use the <span style="font-weight: bold;">-s</span>
    flag with dispread for this. If you want to use a colorimeter as a
    reference instrument, then make sure that it is the first file
    provided to the ccxxmake <span style="font-weight: bold;">-f</span>
    option. The filenames should be concatenated with a <span
      style="font-weight: bold;">","</span> separator without spaces.
    You will also have to supply a display name using the <span
      style="font-weight: bold;">-I</span> option and/or technology
    description using <span style="font-weight: bold;">-T</span>.<br>
    When creating a <span style="font-weight: bold;">CCSS</span> file,
    only spectral readings from the display measured with the reference
    instrument are needed, and a single <span style="font-weight:
      bold;">.ti3</span> file should be provided.<br>
    <br>
    <a name="display"></a>When running on a UNIX based system that used
    the X11 Windowing System, <b>ccxxmake</b> will by default use the
    $DISPLAY environment variable to determine which display and screen
    to read from. This can be overridden by supplying an X11 display
    name to the <span style="font-weight: bold;">-display</span>
    option. Note that if Xinerama is active, you can't select the screen
    using $DISPLAY or -display, you have to select it using the <span
      style="font-weight: bold;">-d</span> parameter.<br>
    <br>
    <a name="d"></a> By default the main display will be the location of
    the test window. If the system has more than one display or screen,
    an alternate display/screen can be selected with the <span
      style="font-weight: bold;">-d</span> parameter. If you invoke <b>ccxxmake</b>
    so as to display the usage information (i.e. "dispcal -?" or
    "dispcal --"), then the discovered displays/screens will be listed.
    Multiple displays may not be listed, if they appear as a single
    display to the operating system (ie. the multi-display support is
    hidden in the video card driver). On UNIX based system that used the
    X11 Windowing System, the <span style="font-weight: bold;">-d</span>
    parameter will override the screen specified by the $DISPLAY or
    parameter.<br>
    <br>
    <a name="dnm"></a>Because of the difficulty cause by TwinView and
    MergedFB in X11 based systems, you can optionally specify a separate
    display number after the display that is going to be used to present
    test patches, for accessing the VideoLUT hardware. This must be
    specified as a single string, e.g. <span style="font-weight: bold;">-d




















      1,2</span> . Some experimentation may be needed using <a
      href="dispwin.html">dispwin</a> on such systems, to discover what
    screen has access to the VideoLUT hardware, and which screens the
    test patches appear on.<br>
    <br>
    <span style="font-weight: bold;"><a name="dweb"></a>-dweb</span> or
    <span style="font-weight: bold;">-dweb:port</span> starts a
    standalone web server on your machine, which then allows a local or
    remote web browser to display the the color test patches. By default
    port <span style="font-weight: bold;">8080</span> is used, but this
    can be overridden by appending a <span style="font-weight: bold;">:</span>
    and the port number i.e. <span style="font-weight: bold;">-dweb:8001</span>.
    The URL will be <span style="font-weight: bold;">http://</span>
    then name of the machine or its I.P. address followed by a colon and
    the port number - e.g something like <span style="font-weight:
      bold;">http://192.168.0.1:8080</span>. If you use the verbose
    option (<span style="font-weight: bold;">-v</span>) then a likely
    URL will be printed once the server is started, or you could run <span
      style="font-weight: bold;">ipconfig</span> (MSWin) or <span
      style="font-weight: bold;">/sbin/ifconfig</span> (Linux or OS X)
    and identify an internet address for your machine that way. You may
    have to modify any firewall to permit port 8080 to be accessed on
    your machine.<br>
    <br>
    <a name="dmadvr"></a><span style="font-weight: bold;">-dmadvr</span>
    [MSWin only] causes test patches to be displayed using the MadVR
    video renderer. Note that will have to start <b>MadTPG</b> before
    running ccxxmake, and that while you can adjust the "Test Pattern
    Configuration" controls, you should <u>not</u> normally alter the
    "Existing Calibration" controls, as ccxxmake will set these
    appropriately. <br>
    <br>
    <a name="dcc"></a><span style="font-weight: bold;">-dcc</span> or <b>-dcc:<i>no</i></b>
    causes test patches to be displayed using and available <a
      href="http://en.wikipedia.org/wiki/Chromecast">ChromeCast</a> to
    your TV. Use <b>-dcc:?</b> to display a list of ChromeCasts on your
    local network. You may have to modify any firewall to permit port
    8081 to be accessed on your machine if it falls back to the Default
    receiver.<br>
    <br>
    <a name="p"></a>The <span style="font-weight: bold;">-p</span> flag
    allows measuring in telephoto mode, using instruments that support
    this mode, e.g. the ColorMunki. Telephoto mode is one for taking
    emissive measurements from a distance (ie. telespectometer,
    tele-colorimeter) mode, and typically would be used for measuring
    projector type displays. If a device does not support a specific
    telephoto mode, then the normal emissive mode may be suitable for
    measuring projectors.<br>
    <br>
    <a name="y"></a> The <span style="font-weight: bold;">-y</span>
    flag allows setting the Display Type used as a base for color
    correction matrix CCMX creation. Only base calibration display types
    will be listed. The selection typically determines two aspects of of
    the instrument operation: <span style="font-weight: bold;">1)</span>
    It may set the measuring mode to suite <a
      href="http://en.wikipedia.org/wiki/Comparison_of_display_technology"><span
        style="font-weight: bold;">refresh</span> or <span
        style="font-weight: bold;">non-refresh</span> displays</a>.
    Typically only LCD (Liquid Crystal) displays have a non-refresh
    nature. <span style="font-weight: bold;">2)</span> It may select an
    instrument internal calibration matrix suitable for a particular
    display type. The selections available depends on the type and model
    of instrument, and a list of the options for the discovered
    instruments will be shown in the <a href="ArgyllDoc.html#CmdLine">usage</a>
    information. For more details on what particular instruments support
    and how this works, see <a href="instruments.html">Operation of
      particular instruments</a>. Any CCMX created will work on top of
    the selected Display Type, so to be valid, the same Display Type
    must be selected whenever the CCMX is used with this instrument.
    Installed CCMX files will automatically select the appropriate base
    type.<br>
    <br>
    <a name="z"></a>The <b>-z</b> flag allows setting a different
    Display Type for the reference spectral instrument, such as refresh
    or non-refresh type, if it supports it. You may have to use this if
    you are setting a specific base type for the colorimeter using -y,
    and the spectrometer doesn't have this display type.<br>
    <br>
    <a name="P"></a> The <span style="font-weight: bold;">-P</span>
    parameter allows you to position and size the test patch window. By
    default it is places in the center of the screen, and sized
    appropriately for the type of instrument. The <span
      style="font-weight: bold;">ho</span> and <span
      style="font-weight: bold;">vo</span> values govern the horizontal
    and vertical offset respectively. A value of 0.0 positions the
    window to the far left or top of the screen, a value of 0.5
    positions it in the center of the screen (the default), and 1.0
    positions it to the far right or bottom of the screen. If three
    parameters are provided, then the <span style="font-weight: bold;">ss</span>
    parameter is a scale factor for the test window size. A value of 0.5
    for instance, would produce a half sized window. A value of 2.0 will
    produce a double size window. If four parameters are provided, then
    the last two set independent horizontal and vertical scaling
    factors. Note that the ho,vo,ss or ho,vo,hs,vs numbers must be
    specified as a single string (no space between the numbers and the
    comma). For example, to create a double sized test window at the top
    right of the screen, use <span style="font-weight: bold;">-P 1,0,2</span>
    . To create a window twice as wide as high: <span
      style="font-weight: bold;">-P 1,0,2,1</span>.<br>
    <br>
    <a name="F"></a> The <span style="font-weight: bold;">-F</span>
    flag causes the while screen behind the test window to be masked
    with black. This can aid black accuracy when measuring CRT displays
    or projectors.<br>
    <br>
    <a name="n"></a><span style="font-weight: bold;">-n</span> When
    running on a UNIX based system that used the X11 Windowing System, <b>dispcal</b>
    normally selects the override redirect so that the test window will
    appear above any other windows on the display. On some systems this
    can interfere with window manager operation, and the <b>-n</b>
    option turns this behaviour off.<br>
    <br>
    <a name="N"></a><span style="font-weight: bold;">-N</span> Any
    instrument that requires regular calibration will ask for
    calibration on initial start-up. Sometimes this can be awkward if
    the instrument is being mounted in some sort of measuring jig, or
    annoying if several sets of readings are being taken in quick
    succession. The -<span style="font-weight: bold;">N</span>
    suppresses this initial calibration if a valid and not timed out
    previous calibration is recorded in the instrument or on the host
    computer. It is advisable to only use this option on the second and
    subsequent measurements in a single session.<br>
    <br>
    <a name="L"></a> The -<span style="font-weight: bold;">H</span>
    option on high resolution spectral mode, if the instrument supports
    it, such as the Eye-One Pro. See <a href="instruments.html">Operation



















      of particular instruments</a> for more details. This may give
    better accuracy for display measurements.<br>
    <br>
    <a name="C"></a> The -<span style="font-weight: bold;">C</span> <span
      style="font-weight: bold;">"command" </span>option allows a
    method of relaying each test value to some other display than that
    on the system running dispcal (for instance, a photo frame, PDA
    screen etc.), by causing the given command to be invoked to the
    shell, with six arguments. The first three arguments are the RGB
    test color as integers in the range 0 to 255, the second three
    parameters are the RGB test color as floating point numbers in the
    range 0.0 to 1.0. The script or tool should relay the given color to
    the screen in some manner (e.g. by generating a raster file of the
    given color and sending it to the display being profiled), before
    returning. Note that a test window will also be created on the
    system running dispread.<br>
    <br>
    <a name="o"></a> (CCMX creation) The <b>-o</b> flag allows
    specifying a tristimulus observer, and is used to compute
    tristimulus values from spectral readings.&nbsp; The following
    choices are available:<br>
    <b>&nbsp; 1931_2</b> selects the standard CIE 1931 2 degree
    observer. The default.<br>
    &nbsp; <b>1964_10</b> selects the standard CIE 1964 10 degree
    observer.<br>
    &nbsp; <b>1955_2</b> selects the Stiles and Birch 1955 2 degree
    observer<br>
    &nbsp; <b>1978_2 </b>selects the Judd and Voss 1978 2 degree
    observer<br>
    &nbsp; <b>shaw</b> selects the Shaw and Fairchild 1997 2 degree
    observer<br>
    <br>
    <a name="s"></a>The <b>-s steps</b><span style="font-weight: bold;"></span>
    parameter overrides the default number of test patch combination
    steps used in measuring a colorimeter &amp; display combination.<span
      style="font-weight: bold;"></span><span style="font-weight: bold;"></span><span
      style="font-weight: bold;"></span>&nbsp; The steps are those out
    of every combination of R,G &amp; B values of the given number of
    steps that have at least one colorant at 100%. So 2 steps gives 7
    test patches, 3 gives 19, 4 gives 37, 5 gives 61, 6 gives 91 etc.
    Note that typically this won't make much difference to the resulting
    calibration, since it depends primarily on the underlying spectral
    characteristics of the display.<br>
    <br>
    <a name="W"></a>The <b>-W</b> <span style="font-weight: bold;">n|h|x</span>
    parameter overrides the default serial communications flow control
    setting. The value <span style="font-weight: bold;">n</span> turns
    all flow control off, <span style="font-weight: bold;">h</span>
    sets hardware handshaking, and <span style="font-weight: bold;">x</span>
    sets Xon/Xoff handshaking. This commend may be useful in workaround
    serial communications issues with some systems and cables. <br>
    <br>
    <a name="D"></a>The <b>-D</b> flag causes communications and other
    instrument diagnostics to be printed to stdout. A level can be set
    between 1 .. 9, that may give progressively more verbose
    information, depending on the instrument. This can be useful in
    tracking down why an instrument can't connect.<br>
    <br>
    <a name="E"></a>The <b>-E</b> parameter allows overriding the <span
      style="font-weight: bold;">ccmx/ccss</span> files overall
    description tag. Normally this is not necessary. With most command
    line shells, it will be necessary to enclose the parameter with
    double quotes, so that spaces and other special characters are
    included in the parameter, and not mistaken for the start of another
    flag, or as a final command line parameter. <br>
    <br>
    <a name="I"></a>The <b>-I</b> parameter allows optional setting of
    the display description string in the resulting <span
      style="font-weight: bold;">ccmx/ccss</span> file. Since the
    default display description is probably very generic, it is <span
      style="font-weight: bold;">highly recommended</span> that a
    description of the make and model of the display be provided here.
    The default or given display description will be printed before the
    menu. With most command line shells, it will be necessary to enclose
    the parameter with double quotes, so that spaces and other special
    characters are included in the parameter, and not mistaken for the
    start of another flag, or as a final command line parameters.<br>
    <br>
    <a name="T"></a>The <b>-t</b> parameter allows setting of the
    display technology type from the available list. You can get a usage
    that includes the list using "ccxxmake -??". This is a required
    parameter, since it conveys information about the refresh type and
    settling time of the display. If the specific details of the display
    are not known (i.e. backlight type, pannel type etc.), then choose
    the next most generic type. If none of these are applicable, choose
    "Unknown".<br>
    <br>
    <a name="U"></a>The <b>-U</b> parameter allows setting of the user
    interface selection character this display type can be selected by,
    if installed. This character will only be used if there is no clash
    with any preceding selections. Characters in the range 0-9, A-Z a-z
    can be used.<br>
    <br>
    <a name="Yrn"></a>The -<span style="font-weight: bold;">Y r </span>and















    <b>-Y n</b> options overrides the refresh display mode set by the <a
      href="spotread.html#y">-y display type selection</a>, with <b>-Y</b><span
      style="font-weight: bold;"> r</span> forcing refresh display mode,
    and <b>-Y n</b> forcing a non-refresh display mode. Not all
    instruments support a display measurement refresh mode, or the
    ability to override the mode set by the display type selection.<br>
    <br>
    <a name="YR"></a> The -<span style="font-weight: bold;">Y R:<i>rate</i></span>
    options overrides calibration of the instrument refresh rate. This
    may be useful if the instrument supports this function and the
    refresh rate cannot be accurately calibrated from the display
    itself.<br>
    <br>
    <a name="YA"></a> The -<span style="font-weight: bold;">Y A</span>
    option uses a non-adaptive integration time emission measurement
    mode, if the instrument supports it, such as the Eye-One Pro or
    ColorMunki. By default an adaptive integration time measurement mode
    will be used for emission measurements, but some instruments support
    a fixed integration time mode that can be used with display devices.
    This may give increased consistency and faster measurement times,
    but may also give less accurate low level readings.<br>
    <br>
    <a name="file1"></a>The <span style="font-weight: bold; font-style:
      italic;">correction.ccmx</span> is the name of the file to save
    the resulting <a href="File_Formats.html#.ccmx">Colorimeter
      Correction Matrix</a> to. It is best to give it a short but
    informative name that includes the Colorimeter model and the display
    make and model. By convention it should have a <span
      style="font-weight: bold;">.ccmx</span> file extension.<br>
    <br>
    <a name="file2"></a>The <span style="font-weight: bold; font-style:
      italic;">correction.ccss</span> is the name of the file to save
    the resulting <a href="File_Formats.html#.ccss">Colorimeter
      Calibration Spectral Samples</a> to. It is best to give it a short
    but informative name that includes the display technology or model.
    By convention it should have a <span style="font-weight: bold;">.ccss</span>
    file extension.<br>
    <br>
    If you are going to use the same CCMX or CCSS file all the time,
    then you may want to set the <a href="Environment.html">ARGYLL_COLMTER_CAL_SPEC_SET</a>
    environment variable.<br>
    <br>
    <hr style="width: 100%; height: 2px;">
    <h3>Instrument Communications:</h3>
    Unlike the other measurement utilities,<span style="font-weight:
      bold;"> ccxxmake</span> doesn't connect to the instrument until it
    is about to make a measurement. This allows for the possibility of
    using a different instrument for each measurement.<br>
    <br>
    It will display a menu:<span style="font-style: italic;"></span><br>
    <br>
    Press 1 .. 4:<br>
    1) Select an instrument, Currently 1 'usb:/bus4/dev2/ (GretagMacbeth
    i1 Pro)'<br>
    2) Measure test patches with current instrument<br>
    3) [ Compute Colorimeter Correction Matrix &amp; save it ]<br>
    4) Exit<br>
    <br>
    For creating a CCMX there are two measurements to be made, after
    which the correction matrix can be computed and saved. Before each
    measurement, the instrument may need calibrating. For creating a
    CCSS a single measurement is needed.<br>
    <br>
    &nbsp;A spectral measurement using a spectral instrument is always
    needed.<br>
    <br>
    &nbsp;A measurement using the Colorimeter that the correction matrix
    is being created for is needed in the case of creating a CCMX, but <span
      style="font-weight: bold;">not</span> needed when creating a CCSS.<br>
    <br>
    There will be a message before the menu indicating which of the
    measurements has been completed.<br>
    <br>
    <hr style="width: 100%; height: 2px;">
    <h4>Display Setup:</h4>
    Because ccmx/ccss is measuring spectral matching, the exact levels
    of each channel is not important, so the display settings or
    calibration state shouldn't make any difference to the result, as
    long as it is the same for the readings of both instruments.
    Similarly, the number and variety of test patches shouldn't make a
    huge difference, as long as there is at least Red, Green, Blue and
    White test patches.<br>
