PDF::API2::Resource::XObject::Form - Form-resource object base class for PDF::API2
=head1 SYNOPSIS
$res = PDF::API2::Resource::XObject::Form->new $pdf
Returns a form-resource object. base class for all types of form-xobjects.
=cut
sub new {
my ($class,$pdf) = @_;
my $self;
$class = ref $class if ref $class;
$self=$class->SUPER::new($pdf,pdfkey());
$pdf->new_obj($self) unless($self->is_obj($pdf));
$self->subtype('Form');
$self->{FormType}=PDFNum(1);
$self->{' apipdf'}=$pdf;
return($self);
}
=item $res = PDF::API2::Resource::XObject::Form->new_api $api, $name
Returns a form resource object. This method is different from 'new' that
it needs an PDF::API2-object rather than a Text::PDF::File-object.
=cut
sub new_api {
my ($class,$api,@opts)=@_;
my $obj=$class->new($api->{pdf},@opts);
$obj->{' api'}=$api;
return($obj);
}

=cut

if(@b=@_){

}
@b=$self->{BBox}->elementsof;
return(map { $_->val } @b);
}
=item $res->resource $type, $key, $obj
Adds a resource to the form.
B<Example:>
$res->resource('Font',$fontkey,$fontobj);
$res->resource('XObject',$imagekey,$imageobj);
$res->resource('Shading',$shadekey,$shadeobj);
$res->resource('ColorSpace',$spacekey,$speceobj);
B<Note:> You only have to add the required resources, if
they are NOT handled by the *font*, *image*, *shade* or *space*
methods.
