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 %]bugsummeryperio d.cgi?[% urlquerypart FILTER html %]&type=4&amp ;

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


[code=perl]
}elsif( $cgi->param('type' ) == 4)
{

$vars->{'data'} = \@data;
$template->process("summe ry/report-line1.png.tmpl" , $vars)
|| ThrowTemplateEr ror($template->error());
}
[/code]


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 ThrowTemplateEr ror routine looks like. Therefore, I would bypass it for the moment and see if you can get it to complain.

Change this:
[CODE=perl]|| ThrowTemplateEr ror($template->error());[/CODE]
To:
[CODE=perl] || die $template->error();[/CODE]
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?
