Flickr Collage

Flickr Collage queries the Flickr API for the top-rated image by search keywords and assembles a collage grid from this images to a new file.

You have to install ImageMagick. On Ubuntu for example, you can run:

sudo apt-get install libmagickwand-dev

For more details take a look at (https://github.com/rmagick/rmagick#prerequisites).

Installing via Bundler

Add this line to your application's Gemfile:

gem 'flickr_collage'

And then execute:

bundle

Installing via Rubygems

gem install flickr_collage

Installing from github

git clone https://github.com/plaschczek/flickr_collage
cd flickr_collage
bundle
rake install

First you have to initialize FlickRaw.api_key and FlickRaw.shared_secred.
For example export the following env vars:

export FLICKR_API_KEY='... Your API key ...'
export FLICKR_SHARED_SECRET='... Your shared secret ...'

Or in your Ruby file:

require 'flickr_collage'

FlickRaw.api_key="... Your API key ..."
FlickRaw.shared_secret="... Your shared secret ..."

To create a collage with 10 random images, instantiate a new FlickrCollage and save the image:

FlickrCollage.new.save

Full options example (9 images, 4 by keyword, 5 random in 2 rows as squares, saved as 'tmp/fruits_example.jpg'):

FlickrCollage.new(
  keywords: ['strawberry', 'kiwi', 'cherry', 'limes'],
  filename: 'fruits_example.jpg',
  dir: 'tmp',
  no_of_images: 9,
  rows: 2,
  squares: true
).save

The same full options example as before:

flickr_collage -k strawberry,kiwi,cherry,limes -f fruits_example.jpg -d tmp -n 9 -r 2 -s

And the command line help:

flickr_collage -h

FlickrCollage.new(keywords:, filename:, dir:, no_of_images:, rows:, squares:)

    keywords: Array with keywords
    filename: collage filename, default 'collage.jpg'
         dir: directory to save the collage, has to exist, default '.'
no_of_images: number of images, default number of keywords and without keywords 10
        rows: number of collage rows, default sqrt(no_of_images).floor
     squares: boolean, if true images squared
