App::BlurFill

A simple Perl class for generating blurred background fills for images. Suitable for use in video formatting, social posts, and more.

Usage from Perl

use App::BlurFill;

my $blur = App::BlurFill->new(file => 'input.jpg');
$blur->process;  # writes input_blur.jpg

Pre-built applications

The distribution comes with a couple of complete applications that use App::BlurFill. This will be easier for the end-user to use.

Command line program - blurfill

The blurfill program is a standard command line program. You run it like this:

blurfill [-w width] [-h height] [-o output_filename] image_filename

If width or height are omitted, they default to 650 pixels and 350 pixels respectively. If the output filename is omitted, then one will be generated for you. For example, if you start with picture.png, then your output will be written to picture_blur.png.

Web application

There is also a web application bundled in the standard distribution. You can run it locally using the standard Perl web application runner, plackup.

plackup bin/app.psgi

Once that program is running you can visit the application in your browser by going to http://localhost:5000/.

See the documentation for more information on running web applications using plackup.

Docker container

The web application is also available from the Docker Hub. You can start it by running:

docker run -p 8080:3000 davorg/app-blurfill

Once that is running, you can visit it at http://localhost:8080/ - the port number can be controlled by changing the number in the command.

Demo version

A demo version of the web application is online at:
