png template processing

[akilageethal]

I want to get a png template processed . I am trying to call a CGI script to process the template . for the image url iam giving the CGI script path.


[% imageurl = BLOCK %]bugsummeryperiod.cgi?[% urlquerypart FILTER html %]&type=4&

here iam trying to change the variable 'type ' and call the cgi script. In the cgi script i have a conditional statement for
type ==4

 }elsif( $cgi->param('type') == 4)
 {
 
 $vars->{'data'} = \@data;
     $template->process("summery/report-line1.png.tmpl", $vars)
  || ThrowTemplateError($template->error());
 }
 

now i think still the cgi script is not getting called. What can be the error??

What errors are you getting? Also, what templating system are you using?

I am not getting any compilation errors. But the graph is not displayed in the page. I think still the png template is not processed.

I am not sure what your ThrowTemplateError routine looks like. Therefore, I would bypass it for the moment and see if you can get it to complain.

Change this:

|| ThrowTemplateError($template->error());

To:

 || die $template->error();

Also, is the file name correct? Is it an image or a template page you are wanting to view?

Your png, is it transparent by chance. If so, are you using a browser like Internet Explorer to view it?

Have you searched CPAN for a module to aide in building your graph?
