您将重新制作perl模块以及在OS X,Windows,Linux上最容易处理的图像格式(GIF？,PNG？其他？)？

编辑我的解决方案,基于GD,由Brian Agnew推荐

use strict;
use warnings;
use GD;
my $BitMap = GD::Image->new(400,400);

my $white = $BitMap->colorAllocate(255,255,255);
my $black = $BitMap->colorAllocate(0,0);       

# Frame the BitMap
$BitMap->rectangle(0,399,$black);
# Transparent image,white background color
$BitMap->transparent($white);

# plot some,just to show it works #
for my $x (0..100) {
   for my $y (0 .. 100) {
      $BitMap->setPixel(250+100*sin($x)-$y,150+125*cos($x)+$y,$black); 
   }
}

# write png-format to file
open my $fh,">","test.png" or die "$!";
binmode $fh;
print $fh $BitMap->png;
close($fh);
