pelicanalbums 0.6.1

Pelican-Albums
Pelican-Albums is a plugin for Pelican that helps you to easily manage your
photo albums (or galleries).

Features

Easily reference an image in your album path using {image}album/image.jpg.
Automatically create a thumbnail for an image in your album path using
{thumbnail}album/image.jpg or {thumbnail:NxN@Q}album/image.jpg.
Automatically create album pages by adding a page to an album directory.

Installation
To install pelican-albums to your pelican installation use:
$ pip install pelican-albums
Then, add ‘pelican_albums’ to the plugin list in your publishconf.py:
PLUGINS = ['pelican_albums']

Settings
Pelican-albums provides a couple of settings:

ALBUM_PATH (images): What directory inside content contains your
albums.
THUMBNAIL_OUTPUT_PATH (images/thumbnails): What directory inside
the output directory will be used to store thumbnails.
THUMBNAIL_OUTPUT_FORMAT (JPEG): As what format the thumbnails should
be created (JPEG or PNG).
THUMBNAIL_DEFAULT_SIZE (192x192): What the default size of a
thumbnail should be.
THUMBNAIL_DEFAULT_QUALITY (80): What the default quality of a
JPEG thumbnail should be.
ALBUM_SAVE_AS (albums/{slug}.html): Where to store album indexes.
ALBUM_URL (albums/{slug}.html): The URL scheme to reference an album.

Albums
To create a new album, just create a new directory in the ALBUM_PATH (the
default is content/images) and place the images inside it. Please note that
pelican-albums does not offer facilities to rotate or resize the images for
you (except for creating thumbnails) at this moment.

Thumbnails
Pelican-albums will automatically generate the requested thumbnails at the
requested sizes. It will check the mtime of the original file to that
of the thumbnail to check if the thumbnail should be refreshed.
You can specify the size and quality of a thumbnail on different places:

Inside the {thumbnail} tag: {thumbnail:128x128@80}album/image.jpg
In the metadata of the content: Thumbnail-Size: 128x128@80
As a parameter to the album.thumbnail(spec=None) in your templates.
In the global pelican settings.

A thumbnail size specifier can have a number of different forms:

WIDTHxHEIGHT – Crop and resize an image until a thumbnail of these
exact dimensions is the result (f.e. 192x192).
DIMENSION – Shorthand for DIMENSIONxDIMENSION (f.e. 192).
WIDTHx – Create a thumbnail with the given width but keep the original
aspect ratio so the height might vary (f.e. 192x).
xHEIGHT – Create a thumbnail with the given height but keep the original
aspect ratio so the width might vary (f.e. x192).

You can optionally add an @nn suffix to the size to indicate the thumbnail
quality that should be used (f.e. 192@80 for a 192x192 thumbnail at 80%
quality). This specifies the JPEG file quality and does not apply to PNG
thumbnails.

Album pages
By creating a page inside an album folder, a page will be generated using the
album.html template. Both the album and the page will be available
inside the template. The page object works exactly as the regular pelican
page objects.
The album object has several properties:

images – The images contained in this album.
albums – A list of sub-albums (if any).
pages – The album pages for this album (you can create multiple pages
for each album if you want).

The image objects returned by album.images have the following
properties:

album – The album this image belongs to.
filename – The filename of this image.
url – The URL of this image relative to the site URL.
thumbnail(spec=None) – A method that returns the URL of a thumbnail of
the given (or default) size and quality relative to the site URL.

album.html
An example template for album pages (save this as album.html inside your
templates directory):
{% extends "base.html" %}
{% block title %}{{ page.title }}{%endblock%}
{% block content %}
<article class="page">
<header>
<div class="title">
{{ page.title }}
</div>
</header>

<div class="entry-content">
{{ page.content }}
</div>

<div class="album">
{% for image in album.images %}
<a href="{{ SITEURL }}/{{ image.url }}">
<img src="{{ SITEURL }}/{{ image.thumbnail(page.metadata.get('thumbnail-size')) }}"
title="{{ image.filename }}" />
</a>
{% endfor %}
</div>
</article>
{% endblock %}
