This is a little example with Image::Magick:

#!/usr/bin/perl

use Image::Magick;

# create an image, white background, and save it

$base = Image::Magick->new();
$base->Set(size => '640x480');
$base->ReadImage('xc:orange');
$base->Write('./background.jpg');

# draw some text, crop it and save in a new image

$tile = Image::Magick->new();
$tile->Set(size => '600x200');
$tile->ReadImage('xc:white');
$tile->Annotate(font      => 'times.ttf',
                pointsize => 12,
                fill      => 'navy',
                text      => 'www.perlmonks.org',
                x         => 100,
                y         => 100);
$tile->Crop('0x0');
$tile->Write('./tile.jpg');

# read background

$image = Image::Magick->new();
$image->Read('./background.jpg');

# draw a red pixel

$image->Set('pixel[50,50]' => 'red');

# read another image

$image2 = Image::Magick->new();
$image2->Read('./tile.jpg');

# compose them

$image->Composite(image   => $image2,
                  compose => 'Over',
                  x       => 150,
                  y       => 150);

$image->Write('composition.jpg');
