There is a Mandelbrot folder inside the Imager source tree. It looks like one can specify a filter to Imager. To build, I set the CPATH environment due to unable to find imconfig.h.
$ cpanm Imager
$ wget https://cpan.metacpan.org/authors/id/T/TO/TONYC/Imager-1.012.ta
+r.gz
$ tar xf Imager-1.012.tar.gz && cd Imager-1.012/Mandelbrot
$ perl Makefile.PL
$ CPATH=~/perl5/perlbrew/perls/perl-5.32.1/lib/site_perl/5.32.1/x86_64
+-linux-thread-multi/Imager/include make
$ make install
Running make test inside the Mandelbrot folder fails for me, so I created a script. Rendering and output to PNG takes 0.131 seconds.
use strict;
use warnings;
use Imager;
use Imager::Filter::Mandelbrot;
my $im = Imager->new(xsize => 1000, ysize => 1000);
$im->filter(type => 'mandelbrot',) or die("# ", $im->errstr, $/);
$im->write(file => 'mandel1.png');
The C code calls i_ppix per each pixel.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
