SYNOPSIS¶
# lib/MyApp/View/GD.pm
package MyApp::View::GD;
use base 'Catalyst::View::GD';
1;
# configure in lib/MyApp.pm
MyApp->config({
...
'View::GD' => {
gd_image_type => 'png', # defaults to 'gif'
gd_image_content_type => 'images/png', # defaults to 'image/$gd_image_type'
gd_image_render_args => [ 5 ], # defaults to []
},
});
sub foo : Local {
my($self, $c) = @_;
$c->stash->{gd_image} = $self->create_foo_image();
$c->forward('MyApp::View::GD');
}
DESCRIPTION¶
This is a Catalyst View subclass which can handle rendering GD based image
content.
CONFIG OPTIONS¶
- gd_image_type
- This defaults to "gif" but should be the name of the method to
call on the GD::Image instance in order to render the images.
- gd_image_render_args
- This is an array ref of values to be passed as an argument to the
GD::Image render method.
- gd_image_content_type
- The default for this is built from the "gd_image_type"
parameter, which in most cases will just work, but in some more specific
rendering methods in GD::Image it will not and you will need to assign
this explicitly.
METHODS¶
- new
- This really just handles consuming the configuration parameters.
- process
- This method will always look in the "gd_image" stash for an
instance of GD::Image and it will then render and serve it according to
the configuration setup.
It is also possible to override the global configuration on a per-request
basis by assigning values in the stash using the same keys as used in the
configuration.
