Data::FormValidator::Filters::ImgData(3pm) User Contributed Perl Documentation Data::FormValidator::Filters::ImgData(3pm)NAMEData::FormValidator::Filters::ImgData - Resize image on the flyVERSIONThis document describes Data::FormValidator::Filters::ImgData version 0.0.3SYNOPSISuse MyWebApp; use CGI::Application::Plugin::JSON qw(to_json); use CGI::Application::Plugin::AJAXUpload; use Data::FormValidator::Filters::ImgData; sub setup { my $c = shift; $c->ajax_upload_httpdocs('/var/www/vhosts/mywebapp/httpdocs'); my $profile = $c->ajax_upload_default_profile; $profile->{field_filters}->{value} = filter_resize(300,200); $c->ajax_upload_setup( run_mode=>'file_upload', upload_subdir=>'/img/uploads', dfv_profile=>$profile, ); return; }DESCRIPTIONThis module rewrites and formats an image. It is intended specifically to work with CGI::Application::Plugin::AJAXUpload and hence Data::FormValidator. Unlike, for example Data::FormValidator::Filters::Image, it takes raw image data and returns raw image data.INTERFACEfilter_resize This returns the subroutine reference that does the work. It takes as arguments the width and height in that order. There is an optional third argument which is the format. This defaults to "jpeg" but can be anything that works as a method on a GD::Image object returning image data.ACKNOWLEDGEMENTSThe core of the code is copied from Image::Resize. However the constructor for that module does not take raw data.DEPENDENCIESThis module uses the GD module.BUGS AND LIMITATIONSPlease report any bugs or feature requests to "bug-cgi-application-plugin-ajaxupload@rt.cpan.org", or through the web interface at <http://rt.cpan.org>.AUTHORNicholas Bamber "<nicholas@periapt.co.uk>"LICENCE AND COPYRIGHTCopyright (c) 2010, Nicholas Bamber "<nicholas@periapt.co.uk>".
