Hi,

I'm trying to write a script that will:

1: Grab an image (a pre-defined one)
2) Overlay some text (the date) over this image.

I've had a google around, and can't find anything (unless I'm not searching for the correct queries =))

Could anyone provide me with some example code? At the moment, I've got the basics - but need to have an image showing towards the back of the image:

#!/usr/local/bin/perl

    use CGI::Carp qw(fatalsToBrowser);
    print qq|Content-type: image/png \n\n|;

    use GD;

    # create a new image
    my $im = new GD::Image(100,100);

    # allocate some colors
    my $white = $im->colorAllocate(255,255,255);
    my $black = $im->colorAllocate(0,0,0);       
    my $red = $im->colorAllocate(255,0,0);      
    my $blue = $im->colorAllocate(0,0,255);

    # make the background transparent and interlaced
    $im->transparent($white);
    $im->interlaced('true');

    # Put a black frame around the picture
    $im->rectangle(0,0,99,99,$black);

    # Draw a blue oval
    $im->arc(50,50,95,75,0,360,$blue);

    # And fill it with red
    $im->fill(50,50,$red);

#   my $courier = GD::Font->load('/home/trust/domain.pro/cgi-bin/trust
+/LiberationSerif-Bold.ttf') or die "Can't load font";
    $im->string(gdSmallFont,5,10,"Testing",$black);

    # make sure we are writing to a binary stream
    binmode STDOUT;

    # Convert the image to PNG and print it on standard output
    print $im->png;
