NAME
oyranos-profile-graph - ICC profile graph tool

SYNOPSIS
oyranos-profile-graph [-o FILENAME] [-x [-c]] [-w NUMBER] [-b] [-s] PROFILENAMES
oyranos-profile-graph [ -h ]

DESCRIPTION
The oyranos-profile-graph programm converts ICC profiles or embedded ICC profiles from images to a graph image. By default the program shows the saturation line of the specified profiles and writes to output.png .

OPTIONS

PROFILENAMES
    2D Graph from profiles

    -x use CIE*xyY *x*y plane for saturation line projection.

    -c with -x omit white line of lambert light emitters in CIE*xyY *x*y plane

    -s omit the spectral line.

    -d FLOATINGPOINTNUMBER incrementally increase the thickness of the graph lines. The default is 0.7 .

--standard-observer
    show the standard observer 1931 2° color matching function (CMF) as curves.

    --no-color draw in gray

--standard-observer-64
    show the standard observer 1964 2° color matching function (CMF) as curves.

    --no-color draw in gray

--kelvin NUMBER
    show the blackbody radiator spectrum as curves.

    --no-color draw in gray

--illuminant NAME
    show illuminant spectrum as curves.

    --illuminant A show the CIE A spectral power distribution (SPD)

    --illuminant D65 show the CIE D65 spectral power distribution, ~ 6500 Kelvin daylight

    --no-color draw in gray

GENERAL OPTIONS

-v, --verbose
    increase verbosity

-w NUMBER
    set output image width in pixel

-o FILENAME
    write resulting image to file name.

-b  omit border.

-t FLOATINGPOINTNUMBER
    increase the thickness of the graph lines

-h, --help
    print a help text

ENVIRONMENT

OY_DEBUG
    set the Oyranos debug level. Alternatively the -v option can be used.

XDG_DATA_HOME XDG_DATA_DIRS
    route Oyranos to top directories containing resources. The derived paths for ICC profiles have a "color/icc" appended.

EXAMPLES

Show the saturation lines of two profile in CIE*ab 256 pixel width, without spectral line and with thicker lines:
    oyranos-profile-graph -w 256 -s -t 3 sRGB.icc ProPhoto-RGB.icc

Show the standard observer spectral function as curves:
    oyranos-profile-graph --standard-observer -o CIE-StdObserver.png
