NAME

Raku interface to the Gd graphics library.

DESCRIPTION

Raku interface to Thomas Boutell's gd graphics library. GD allows you to create color drawings using a large number of graphics primitives, and emit the drawings in multiple formats.

You will need the Linux gd-libgd library or MacOS gd2 port installed in order to use GD (preferably a recent version).

SYNOPSIS

use GD;

if GD::Image.new(200, 200) -> $image {

    my $black = $image.colorAllocate(
      red => 0, green => 0, blue => 0
    );

    my $white = $image.colorAllocate(
      red => 255, green => 255, blue => 255
    );

    my $red   = $image.colorAllocate("#ff0000");
    my $green = $image.colorAllocate("#00ff00");
    my $blue  = $image.colorAllocate(0x0000ff);

    $image.rectangle(
      location => (10, 10),
      size     => (100, 100),
      fill     => True,
      color    => $white
    );

    $image.line(
      start => (10, 10),
      end   => (190, 190),
      color => $black
    );

    my $png_fh = $image.open("test.png", "wb");

    $image.output($png_fh, GD_PNG);

    $png_fh.close;

    $image.destroy();
}
