Friends,
I am learning about GD.pm and CGI programming and I tried this ...
#!/usr/local/bin/perl -w
###
###
use strict;
use CGI;
use CGI::Carp qw /fatalsToBrowser/;
my $out = new CGI;
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);
#write to image.png
open( FH, '>image.png' ) or die "Can't image.png:$!\n";
# make sure we are writing to a binary stream
binmode FH;
# Convert the image to PNG and print it on standard output
print FH $im->png;
close FH;
print $out->header( 'text/html' );
print <<HTML;
<html>
<head><title>GD test</title></head>
<body>
<img src='image.png'>
</body>
</html>
HTML
When I run from the command line I get this ...
~/cgi-bin/GD$ ./GDtest.pl
Content-Type: text/html; charset=ISO-8859-1
<html>
<head><title>GD test</title></head>
<body>
<img src='image.png'>
</body>
</html>
But when I execute the CGI with my browser all I get is broken image?
Can anyone give me a pointer or two?
Thanks
