WWW::Misc::Image -
Nothing exported by default
props_to_resize_str, resize_str_to_props, image_convert, image_dims, image_size
This module requires these other modules and libraries:
Try::Tiny
Data::Hub::Util
Error::Logical
Perl::Module
Data::Hub
Error::Programatic
Image::Size
Perl::Options
Parse::Template::Standard
options: See "image_dims"
-out_dir => $abs_path # default is same dir as $path
-grayscale => 1 # convert to grayscale
-watermark => <Hash> # watermark image
-maxdpi => 1 # keep original image path/size
-resize => WxH/wxh # Resize to max W by H and min w by h
A resize string like this:
800x600/480x320
Becomes
max_x => 800
max_y => 600
min_x => 480
min_y => 320
Resize strings may omit dimensions, in which case they will default to zero
800 max_x => 800
800x600 max_x => 800, max_y => 600
800x600/480 max_x => 800, max_y => 600, min_x => 480
800/480 max_x => 800, min_x => 480
A shorthand of a single number ending with a caret (^) indicates all the dimensions are the same, and we a producing a zoomed (as opposed to a letter-box image).
100^ same as 100x100/100x100
This example will not abort:
use WWW::Misc::Image qw(resize_str_to_props);
This example:
my $props = resize_str_to_props('800');
join(';', map { $_ . '=' . $$props{$_} } sort keys %$props);
will return:
max_x=800;max_y=0;min_x=0;min_y=0
This example:
my $props = resize_str_to_props('800x600');
join(';', map { $_ . '=' . $$props{$_} } sort keys %$props);
will return:
max_x=800;max_y=600;min_x=0;min_y=0
This example:
my $props = resize_str_to_props('800x600/480');
join(';', map { $_ . '=' . $$props{$_} } sort keys %$props);
will return:
max_x=800;max_y=600;min_x=480;min_y=0
This example:
my $props = resize_str_to_props('800/480');
join(';', map { $_ . '=' . $$props{$_} } sort keys %$props);
will return:
max_x=800;max_y=0;min_x=480;min_y=0
This example:
my $props = resize_str_to_props('100/z');
join(';', map { $_ . '=' . $$props{$_} } sort keys %$props);
will return:
flags=z;max_x=100;max_y=0;min_x=0;min_y=0
This is the inverse of resize_str_to_props.
This example will not abort:
use WWW::Misc::Image qw(props_to_resize_str);
This example:
props_to_resize_str({max_x => 800});
will return:
800
This example:
props_to_resize_str({max_x => 800, max_y => 600});
will return:
800x600
This example:
props_to_resize_str({max_x => 800, min_x => 480});
will return:
800/480
This example:
props_to_resize_str({max_x => 100, max_y => 100,min_x => 100, min_y => 100});
will return:
100x100/100x100
This example:
props_to_resize_str({max_x => 100, flags => 'z'});
will return:
100/z
options:
-resize=WxH/wxh Resize to max W by H and min w by h
--or--
-max_x=n Maximum width
-max_y=n Maximum height
-min_x=n Minimum width
-min_y=n Minimum height
my ($w,$h) = image_dims( "/images/laura.jpg", -max_x => 50, -max_y => 50 );
my ($w,$h) = image_dims( "/images/laura.jpg", -resize => '50x50' );
Zoomed image:
my ($w,$h,$z) = image_dims( "/images/laura.jpg", -resize => '50^' );
This example will not abort:
use WWW::Misc::Image qw(image_dims);
This example will return false:
image_dims("/foo");
