DESCRIPTION

22       Mojolicious::Plugin::AssetPack::Pipe::Png can be used to crush "png"
23       image files.
24
25       This plugin has default settings for "pngquant" (default) and
26       "optipng". Which will be the default in the future is unknown, so force
27       the one you want in case that matters.
28
29       This pipe is EXPERIMENTAL. Feedback wanted.

ATTRIBUTES

36   app
37         $str = $self->app;
38         $self = $self->app("pngquant");
39
40       Can be used to set a custom application.
41
42   app_args
43         $array = $self->app_args;
44         $self = $self->app_args([qw(-clobber $input)]);
45
46       Can be used to set custom "app" arguments. The special $input string in
47       the argument list will be replaced with the path to a temp file holding
48       the image data.
49
50       If no $input element is found in the "app_args" list, then STDIN and
51       STDOUT will be used instead.
