[Catalyst] Opening existing PDF with Catalyst::View::PDF::API2

[Adam Witney]

Hi, thanks for your reply

> I haven't used it, but looking at the last paragraph of the docs for ``process`` https://metacpan.org/pod/Catalyst::View::PDF::API2#process I notice they say to use $c->stash->{pdf_filename} = 'myfile.pdf'; to set the PDF 
> filename. They also mention what filename is assumed by default.

I think this "filename" defines the filename of the downloaded file rather than an input file

> ->open is a class method of PDF::API2, and I think you only get object methods with the object provided by Catalyst::View::PDF::API2

I think that this is the problem, I can in fact get it to work if I change PDF::API2.pm from

184 sub open_scalar {
185     my ($class, $content, %options) = @_;
186
187     my $self = {};
188     bless $self, $class;

To

184 sub open_scalar {
185     my ($class, $content, %options) = @_;
186
187     my $self = {};
188     if ( ref($class) ) {
189         $self = $class;
190     } else {
191         bless $self, $class;
192     }

This is obviously not an ideal fix but I don't understand how C::V::PDF::API2 interacts with PDF::API2, ie where does the TT pdf object come from?
 
Thanks again for your help

Adam
