Re: Using Unicode chars in GD

I don't know about GD, but i just recently did this using Image::Magick, so perhaps either the same technique of the \x codes will work in GD or if it's possible you can use ImageMagick for your solution instead of GD...

  use Image::Magick;
  my $image = Image::Magick->new();
  ...
  $image->Annotate(
    x=>$x, y=>$y, text=>"Up: \x{2191} and Down: \x{2193}",
    font=> '@YOURFONT.TTF', pointsize => 12, stroke => 'black',
  );

That did it. Here's the working GD code, in case anyone is insterested. Many thanks......Steve `use strict; use GD; my $image = GD::Image->new(200,100); my $white = $image->colorAllocate(255,255,255); my $black = $image->colorAllocate(0,0,0); my $uparrow = "\x{2191}"; my $dnarrow = "\x{2193}"; $image->stringFT($black,'/windows/fonts/arial.ttf',12,0,80,50,"up: $up +arrow dn: $dnarrow"); open(OUT,">test.png") or die "Can't open output: $!\n"; binmode OUT; print OUT $image->png; close OUT;` [download]	[reply] [d/l]

use strict;
use GD;
my $image = GD::Image->new(200,100);
my $white = $image->colorAllocate(255,255,255);
my $black = $image->colorAllocate(0,0,0);
my $uparrow = "\x{2191}";
my $dnarrow = "\x{2193}";
$image->stringFT($black,'/windows/fonts/arial.ttf',12,0,80,50,"up: $up
+arrow  dn: $dnarrow");
open(OUT,">test.png") or die "Can't open output: $!\n";
binmode OUT;
print OUT $image->png;
close OUT;
