Looking at the source of the driver module:

81    my $width = $self->width;
82    my $height = $self->height;
83
84    if(uc($self->format) eq 'PNG') {
85    $surface = Cairo::ImageSurface->create(
86        'argb32', $width, $height
87    );
[download]

So it seems that both $width and $height are not defined. I note that the example on the Graphics::Primitive page has:

my $c = Graphics::Primitive::Component->new(
    width => 500, height => 350,
);
[download]

Whereas the example on the Graphics::Primitive::Driver::Cairo page has:

my $c = Graphics::Primitive::Container->new(
    width => 500, height => 350,
);
[download]

I suggest you try adding the width and height parameters when creating the new Component object (or try just using Component instead of Container) and see if that makes a difference.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
