NAME
Data::FormValidator::Filters::Image - Filter that allows you to shrink incoming image uploads using Data::FormValidator
SYNOPSIS
use Data::FormValidator::Filters::Image qw( image_filter );
# Build a Data::FormValidator Profile:
my $my_profile = {
required => qw( uploaded_image ),
field_filters => {
uploaded_image => image_filter(max_width => 800, max_height => 600),
},
};
# Be sure to use a CGI.pm object as the form input
# when using this filter
my $q = new CGI;
my $dfv = Data::FormValidator->check($q,$my_profile);
DESCRIPTION
Many users when uploading image files never bother to shrink them down to a reasonable size. Instead of declining the upload because it is too large, this module will shrink the image down to a reasonable size during the form validation stage.
The filter will try to fail gracefully by leaving the upload as is if the image resize operation fails.
FILTERS
image_filter( max_width => $width, max_height => $height )
This will create a filter that will reduce the size of an image that is being uploaded so that it is bounded by the width and height provided. The image will be scaled in a way that will not distort or stretch the image.
example:
- upload an image that is 800 x 600
- specify a max width of 100 and max height of 100
The resulting image will be 100 x 75, since that is the
largest scaled image we can create that is still within
the bounds we specified.
