<p>ImageMagick must already be installed on your system. Next, get
the <a href="../www/download.html">PerlMagick</a> distribution corresponding to the installed ImageMagick distribution
-(e.g., PerlMagick 6.58 for
-ImageMagick 6.5.8) and unpack it as shown below:</p>
+(e.g., PerlMagick 6.59 for
+ImageMagick 6.5.9) and unpack it as shown below:</p>
-<p class='crt'><span class="crtprompt"> $magick> </span><span class='crtin'>tar xvfz PerlMagick-6.58.tar.gz</span><span class='crtout'></span><span class="crtprompt"> $magick> </span><span class='crtin'>cd PerlMagick</span></p>

<p>Next, edit <kbd>Makefile.PL</kbd> and change LIBS and INC to include the appropriate path information to the required <kbd>MagickCore</kbd> library. You may need paths to JPEG, PNG, TIFF, etc. delegates if they were included with your installed version of ImageMagick. Build and install it like this:</p>
<p class='crt'><span class="crtprompt"> $magick> </span><span class='crtin'>perl Makefile.PL</span><span class='crtout'></span><span class="crtprompt"> $magick> </span><span class='crtin'>make</span><span class='crtout'></span><span class="crtprompt"> $magick> </span><span class='crtin'>make install</span></p>

+<p>Note, reading from or writing to a Perl filehandle may fail under Windows due to different versions of the C-runtime libraries between ImageMagick and the ActiveState Perl distributions or if one of the DLL's is linked with the /MT option.

<p>copies all the images from object <kbd>$p</kbd> to <kbd>$q</kbd>. You can use this method for single or multi-image sequences.</p>
+<p>The Features() method returns features for each channel in the image in each of four directions (horizontal, vertical, left and right diagonals) for the specified distance. The features include the angular second momentum, contrast, correlation, sum of squares: variance, inverse difference moment, sum average, sum varience, sum entropy, entropy, difference variance, difference entropy, information measures of correlation 1, information measures of correlation 2, and maximum correlation coefficient. Values in RGB, CMYK, RGBA, or CMYKA order (depending on the image type).</p>
