Here is the final working solution I came up with. If there is anything I missed please let me know. I don't know if I am using "gensym()" correctly. The main thing that was an issue was rights on the server side.

#!/usr/bin/perl use warnings; use strict; use IPC::Open3; use Symbol; my $cmd = '/usr/local/bin/wkhtmltopdf - -'; my $err = gensym(); my $in = gensym(); my $out = gensym(); my $pdf = ''; my $pid = open3($in, $out, $err, $cmd) or die "could not run cmd : $c +md : $!\n"; my $string = '<html><head></head><body>Hello World!!!<br /><br /><br / +> IMG: <img id="image" src="data:image/gif;base64,R0lGODlhFwAPAKEAAP///w +AAAMzMzLi3tywAAAAAFwAPAAACQIyPqQjtD98RIVpJ66g3hgEYDdVhjThyXSA4aLq2rgp +78hxlyY0/ICAIBhu/HrEEKIZUyk4R1Sz9RFEkaIHNFgAAOw==" /> </body></html>'; print $in $string; close($in); while( <$out> ) { $pdf .= $_ } # for trouble shooting while( <$err> ) { # print "err-> $_<br />\n"; } # for trouble shooting waitpid($pid, 0 ) or die "$!\n"; my $retval = $?; # print "retval-> $retval<br />\n"; print "Content-Disposition: attachment; filename='testPDF.pdf'\n"; print "Content-type: application/octet-stream\n\n"; print $pdf;
