here is my lame attempt:

#!/usr/bin/perl # # 100 simultaneous supernovae collapse into a supermassive blackhole! # This makes a pretty picture by incrementing the sigma values on the # sample data resulting in an animated GIF. Please feel free to hack # it up and post your version! use strict; use warnings; use Imager::Heatmap; my $filename = 'heatmapa.gif'; my @insert ; my @images = (); $| = 1; print "Generating GIF frame "; my $text = Imager->new(xsize=>300,ysize=>30); $text->box( color => Imager::Color->new(255, 255, 255), filled=>1 ); my $black = Imager::Color->new("#000000"); my $font = Imager::Font->new( file => '/usr/share/fonts/open-sans/OpenSans-Semibold.ttf', color => $black, size => 25); my $japh = "Just another Perl hacker,"; $text->string(font=>$font, text=>$japh, color=>$black, x=>1, y=>20); $text->write(file=>'fuck.png', type=>'png') or die "Cannot write: ",$text->errstr; for my $x (0..299){ for my $y (0..24){ my $pix = ($text->getpixel(x=>$x, y=>$y, type=>'8bit')->rgba())[0] +; next if( $pix == 0 ); push @insert, [ $x, $y, $pix ] ; } } for my $x ('1'..'10') { my $hmap = Imager::Heatmap->new( xsize => 300, ysize => 30, xsigma => $x, ysigma => $x, ); $hmap->insert_datas(@insert); push @images, $hmap->draw; print "$x " } print "done!\n"; Imager->write_multi({ file => $filename, transp => 'none', gif_loop => 0, }, @images); print "Saved $filename\n";

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
