原来Perl获取汉字的点阵如此简单

示例脚本应保存为utf8格式
Code: [全选] [展开/收缩] [Download] (Untitled.pl)

use GD;
use utf8;
my $gd = GD::Image->new(40, 20);       #1
my $black = $gd->colorAllocate(  0,   0,   0);
my $white = $gd->colorAllocate(255, 255, 255);
$gd->stringTTF($white, "C:\\windows\\fonts\\msyh.ttf", 20, 0, 0, 20, "中");
 
my $dt = $gd->wbmp( $black );
my @dts = map { ord($_) } split('', $dt);
 
for my $e (4 .. $#dts)
{
    printf "%08b", $dts[$e];
    if (($e-4+1) % 5 == 0 )
    {
        print "\n";
    }
}
