Sections
========

A gallery is composed of a succession of sections as you can see on this `wonderfully
totally uninteresting example
gallery <http://psycojoker.github.io/prosopopee/first_gallery/>`_. This gallery is
split in 5 sections:

* a full screen picture with text written on it
* a picture with borders around it
* a group of 5 pictures
* and a full-screen picture without text on it this time

In your settings.yaml, a section will **always** have a ``type`` key
that will describe its kind and additional data. Underneath, the
``type`` key is actually the name of an HTML template and the other
data will be passed to this template.

You can find all the section templates here: 

https://github.com/Psycojoker/prosopopee/tree/master/prosopopee/themes/exposure/templates/sections

You often have an ``image`` key. You need to give it a path to the
actual file. By convention, those files are put inside your gallery folder but
this is not mandatory.

Full Screen picture
___________________

This displays a full screen picture as shown in the `example
gallery <http://psycojoker.github.io/prosopopee/first_gallery/>`_ in the first
and last sections. How you should use it:

With text::

  - type: full-picture
    image: big_picture.jpg
    text:
      title: Big picture title
      sub_title: Some text
      date: 2016-01-15
      date_end: 2016-01-24 (Optional)

Without text::

  - type: full-picture
    image: big_picture.jpg
  
If you want a fixed background you can use this option (only with the exposure theme)::

  - type: full-picture
    fixed: true

Bordered picture
________________

This displays a centred picture that is surrounded by white (the background) as
shown in the second position of the `example
gallery <http://psycojoker.github.io/prosopopee/first_gallery/>`_.

How to use it::

  - type: bordered-picture
    image: another_picture.jpg

Group of pictures
_________________

This displays a group of zoomable pictures on one or multiple lines as shown on
the fourth position (after the text) of the `example
gallery <http://psycojoker.github.io/prosopopee/first_gallery/>`_::

  - type: pictures-group
    images:
      -
        - image1.jpg
        - image2.jpg
        - image3.jpg
      -
        - image4.jpg
        - image5.jpg

The first level `-` represents a row of pictures.
The second level `-` represents the list of images in this line.

**Known bug**: the images are left aligned, so if you don't put enough images on
a row, you'll have some white space on the right.

Text
____

This displays some centred text as shown on the third position of the `example
gallery <http://psycojoker.github.io/prosopopee/first_gallery/>`_. HTML is
allowed inside the text.

How to use it::

  - type: text
    text: Some text, HTML <b>is allowed</b>.

Paragraph
_________

This displays a h2 title followed by text. HTML is allowed inside the text.
If no title is declared, a separator is added.

How to use it::

  - type: paragraph
    title: the title
    text: Some text, HTML <b>is allowed</b>.

Since version 0.5 you can add a floating image in the paragraph::

  - type: paragraph
    title: the title
    text: Some text, HTML <b>is allowed</b>.
    image: image.jpg
      float: right 
      size: 150px

By default if you don't set float and size the image will be on left with a size of 250px.

HTML
____

This section is for raw html that will be centred (for example: inlining an OSM iframe).

How to use it::

  - type: html
    html: <tag>some html stuff</html>

For bordered-picture, full-picture and pictures-group, it's possible to use
video instead of pictures. You have to specify with the "type" key that it's a
video.

The video will be converted using either ffmpeg or avconv (depending on the one
specified in the settings, ffmpeg being the default one).

Example for pictures-group::

  - type: pictures-group
    images:
      -
        - name: video.mp4
          type: video
        - image1.jpeg
        - image2.jpeg
      -
        - image3.jpeg
        - image4.jpeg

Example for bordered-picture::

  - type: bordered-picture
    image:
      name: video.mp4
      type: video

And for full-picture::

  - type: full-picture
    image:
      name: video.mp4
      type: video
    text:
      title: Title Text
      sub_title: Sub title text
      date: 2016-03-11
      date_end: 2016-03-25

You can also use a video as a gallery cover::
