Image Placeholder

A library, command-line script and website for generating placeholder images. See ima.gs for the online version that uses this code.

p5-Image-Placeholder

Perl library, available from CPAN. Comes with a command-line script, used like so:

placeholder --background-color=999 400x300 > test.png

To install this, you will need to be running perl (at least 5.10), and to install it either using the standard cpan command, or better yet cpanm like so:

cpanm --sudo Image::Placeholder

Deploying as a website

If you want to run your own installation of this:

• inside your corporate firewall so as not to leak HTTP_REFERER values out into the internet
• within a fort or other structure without internet access
• on your laptop
• as another competitor in the highly lucrative online placeholder market

you will need to be running perl (at least 5.10), and to install a bunch of modules from cpan. I'd recommend using cpanm, like so:

cpanm --sudo                                \
    Modern::Perl                            \
    GD                                      \
    Plack                                   \
    Plack::Middleware::Expires              \
    Moose                                   \
    MooseX::FollowPBP                       \
    MooseX::Method::Signatures

Once those are installed, clone this repository, cd into it and run the command:

plackup -Ilib placeholder.psgi

which will run it on port 5000.
