<h2><a href="http://www.imagemagick.org/api/MagickCore/magick_8c.html" id="AcquireMagickInfo">AcquireMagickInfo</a></h2>

<p>AcquireMagickInfo() allocates a MagickInfo structure and initializes the members to default values.</p>

<p>The format of the AcquireMagickInfo method is:</p>

<pre class="text">
MagickInfo *AcquireMagickInfo(const char *module, const char *name,)
</pre>

<p>A description of each parameter follows:</p>

<h2><a href="http://www.imagemagick.org/api/MagickCore/magick_8c.html" id="GetMagickPrecision">GetMagickPrecision</a></h2>

<p>GetMagickPrecision() returns the maximum number of significant digits to be printed.</p>

<p>The format of the GetMagickPrecision method is:</p>

<pre class="text">
int GetMagickPrecision(void)
</pre>

<h2><a href="http://www.imagemagick.org/api/MagickCore/magick_8c.html" id="IsMagickCoreInstantiated">IsMagickCoreInstantiated</a></h2>

<p>IsMagickCoreInstantiated() returns MagickTrue if the ImageMagick environment is currently instantiated:  MagickCoreGenesis() has been called but MagickDestroy() has not.</p>

<p>The format of the IsMagickCoreInstantiated method is:</p>

<pre class="text">
MagickBooleanType IsMagickCoreInstantiated(void)
</pre>

<h2><a href="http://www.imagemagick.org/api/MagickCore/magick_8c.html" id="MagickCoreGenesis">MagickCoreGenesis</a></h2>

<p>MagickCoreGenesis() initializes the MagickCore environment.</p>

<p>The format of the MagickCoreGenesis function is:</p>

<pre class="text">
MagickCoreGenesis(const char *path,
  const MagickBooleanType establish_signal_handlers)
</pre>

<p>A description of each parameter follows:</p>

</pre>

<h2><a href="http://www.imagemagick.org/api/MagickCore/magick_8c.html" id="SetMagickPrecision">SetMagickPrecision</a></h2>

<p>SetMagickPrecision() sets the maximum number of significant digits to be printed.</p>

<p>An input argument of 0 returns the current precision setting.</p>

<p>A negative value forces the precision to reset to a default value according to the environment variable "MAGICK_PRECISION", the current 'policy' configuration setting, or the default value of '6', in that order.</p>

<p>The format of the SetMagickPrecision method is:</p>

<pre class="text">
