Perl:将(x,y)像素绘制为单色位图的推荐方法

对于一个家庭项目,我需要将(x,y)坐标绘制到400x400黑白位图上。

您将重新编写什么Perl模块和什么图像格式(GIF)?,巴布亚新几内亚?其他?)在OS X、Windows、Linux上最容易处理吗?

编辑 我的解决方案,基于gd,由Brian Agnew提出

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

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

# Frame the BitMap
$BitMap->rectangle(0,0,399,399,$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);
