NAME Catalyst::Plugin::Images - Generate image tags for static files. SYNOPSIS use Catalyst qw/ Images /; # ... somewhere in your templates [% c.image_tag("foo.png" => "alt text") %]; DESCRIPTION This plugin aims to assist you in generating image tags that contain alt text, a properly escaped src attribute, height and width info, without worrying too much. METHODS image_tag $basename, %attrs This method generates an image tag for the image named $basename, with the extra tags %attr. get_image_info $basename Retrieve the information about the image either from the cache or by searching for it. find_image_file $basename Look inside all the search paths (see "CONFIGURATION") for an image named $basename, and return the full path to it, as a object.. read_image_info $path Given the full path, as a Path::Class::File object, return the attributes to be added to the image. This returns a list with "width" and "height", using "Image::Size". image_path_to_uri $path, $basename Generates a URI using "uri_for" in Catalyst, with the absolute path $path relativized to "uri_base". See . get_cached_image_info set_cached_image_info see "CACHING IMAGE DATA" below. setup Overridden to seed configuration defaults. CONFIGURATION All configuration information is stored under the "images" key. paths This should be an array reference of Path::Class::Dir objects (easily generated with "path_to" in Catalyst) in which to search for images. It defaults to "root/static", "root/images", "root/static/images" by default. uri_base This is the "base" prefix path for URI generation. For example, if an image was found at "/www/static/images/foo.png" and "uri_base" is "/www" then the URI generated with "Catalyst/uri_for" will be for "/static/images/foo.png". CACHING IMAGE DATA The code will call "get_cached_image_info" and "set_cached_image_info" when appropriate. Currently both these operations are no op. You should override this if you care. "get_cached_image_info" receives the base name, and should return the info hash. "set_cached_image_info" receives the base name, and the info hash. It can use this data to expire the cache based on mtime, etc. The info hash contains the keys "width", "height", "uri", and "path". SEE ALSO Catalyst, Catalyst::Plugin::Static::Simple, Image::Size
