<refsect1 id='description'><title>DESCRIPTION</title>
<para>The
<emphasis remap='I'>&hairsp;XcmsTekHVCQueryMaxC&hairsp;</emphasis>
function, given a Hue and Value,
determines the maximum Chroma in TekHVC color space
displayable by the screen.
It returns the maximum Chroma along with the actual Hue
and Value at which the maximum Chroma was found.</para>

<para>The
<emphasis remap='I'>&hairsp;XcmsTekHVCQueryMaxV&hairsp;</emphasis>
function, given a Hue and Chroma,
determines the maximum Value in TekHVC color space
displayable by the screen.
It returns the maximum Value and the actual Hue and Chroma
at which the maximum Value was found.</para>

<para>The
<emphasis remap='I'>&hairsp;XcmsTekHVCQueryMaxVC&hairsp;</emphasis>
function, given a Hue,
determines the maximum Chroma in TekHVC color space displayable by the screen
and the Value at which that maximum Chroma is reached.
It returns the maximum Chroma,
the Value at which that maximum Chroma is reached,
and the actual Hue for which the maximum Chroma was found.</para>

<para>The
<emphasis remap='I'>&hairsp;XcmsTekHVCQueryMaxVSamples&hairsp;</emphasis>
returns nsamples of maximum Value, the Chroma at which that maximum Value
is reached, and the actual Hue for which the maximum Chroma was found.
These sample points may then be used to plot the maximum Value/Chroma
boundary of the screen's color gamut for the specified Hue in TekHVC color
space.</para>

<para>The
<emphasis remap='I'>&hairsp;XcmsTekHVCQueryMinV&hairsp;</emphasis>
function, given a Hue and Chroma,
determines the minimum Value in TekHVC color space displayable by the screen.
It returns the minimum Value and the actual Hue and Chroma at which
the minimum Value was found.</para>
