Package: hexagonit.virtualgallery
hexagonit.virtualgalleryis a Plone add-on that renders a Flash-based 3D virtual gallery.Source code @ GitHubReleases @ PyPISphinx docs @ ReadTheDocsInstallationTo installhexagonit.virtualgalleryyou simply addhexagonit.virtualgalleryto the list of eggs in your buildout, run
buildout and restart Plone. Then, installhexagonit.virtualgalleryusing the
Add-ons control panel.RequirementsPlone4.1 or newerFlash player10.2 or newerBasic usageThis package adds theVirtual 3D gallerydisplay mode to Folder and
Collection. So, go to any folder or collection that contains images and selectVirtual 3D galleryfrom the display drop-down menu.In the gallery each room has enough space for 17 images. If the image source
(Folder or Collection) contains more images then additional rooms will be
automatically created and doors allow the user to travel between the rooms.The gallery can be navigated either by using the mouse or the keyboard. Use
the arrow keys to move within the space (hold down shift to strafe). Clicking
an image with the mouse will concentrate on that image and the image metadata
will become visible when hovering over the image.You can view each image in turn by clicking on the arrow buttons on the left
and right side of the viewer. The viewer can also be put in fullscreen mode
by clicking on the fullscreen button on the top right corner.ConfigurationEach gallery may be configured to use a particular image scale (provided byplone.app.imaging) by
choosing the appropriate scale on theVirtual gallery settingspage. A
link to the settings page will become visible when the context is using the
virtual gallery display.By default the gallery uses the original scale of the images but in case of
large images this may slow down the gallery significantly. Using a smaller
scale version of the images usually improves the loading time and performance.You can also configure new image scales inSite setup › Image handling.
For example, you could define a “HD” scale at 1200x1200 pixels which would
give most current day users a good quality image even in the fullscreen mode.Advanced usageThe Flash viewer is independent of Plone and may be used in any web context,
even another framework or a language environment. The viewer requires two
distinct parts to work:The HTML code to embed the viewer and pass parametersJSON configuration which configures the viewer.Embed codeThe HTML code needs to embed theVirtual3DGallery.swfviewer and pass a
singleflashvarsvariable
calleddataURLto the viewer. This variable must contain the URL to the
JSON configuration file which configures the viewer.If you are embedding the viewer within a page that contains other content it
is also recommended set thewmode=windowflash parameter so that HTML
elements can be positioned above the flash content.By default, this package uses theSWFObjectJavascript library to do the
embedding.JSON configurationThe Flash viewer is driven by the JSON configuration which contains the list
of images to display in the gallery, associated image metadata (title, author,
description) and translations for the UI textual elements, e.g.:{"images": [
    {"url": "http://my.server.com/images/image1.png",
     "title": "Nice scenery",
     "description": "Lorem lipsum..",
     "author": "dokai"},
    {"url": "http://my.server.com/images/image2.png",
     "title": "Screenshot of Foo",
     "description": "Lorem lipsum..",
     "author": "dokai"}
    ],
 "ui": {
    "enterRoomToolTip": "Click to enter",
    "fullscreen": "Fullscreen",
    "loadingImg": "Loading image:",
    "enterRoom": "Entering room [x] of [y]",
    "anaglyph": "Anaglyph"
 },
 "settings": {
    "anaglyphModeEnabled": "false"
 }}The viewer does not care where the images and associated metadata come from so
you can implement any custom logic that puts together the list (custom catalog
queries, structural hierarchies, etc) as long as the resulting JSON document
is valid.The package contains an associatedJSON schemadocument which can be used to validate the JSON
configuration, e.g.:from hexagonit.virtualgallery.schema import GALLERY_DATA_SCHEMA
from validictory import validate
import json

try:
    # Assuming the `my_custom_config` contains the Python
    # data structure with the image information.
    validate(my_custom_config, GALLERY_DATA_SCHEMA)
    json_config = json.dumps(my_custom_config)
except ValueError:
    # Validation failed, do something.
    passYou might want to display the gallery somewhere else or possibly in a
toolbarless new window. To keep all Plone stuff away from the virtual gallery
use a URL like below to only get the title of the gallery and the Flash object
that displays it:http://<path>/<to>/<your>/<gallery>/<folder>/virtualgallery?ajax_load=1&ajax_include_head=1TODOcross-browser testinguse in the wildCreditsIdea, skeleton and sponsoring provided by Hexagon IT Oy.Flash part of the gallery developed by Michal Zwieruho, BlackMoon Design.Plone integration by Nejc Zupan, NiteoWeb Ltd.Changelog1.0 (2011-08-26)Added support for configuring the image scale used in the gallery
on per-context basis.
[dokai]Updated documentation
[dokai]Updated Finnish translations.
[dokai]Support for translations added.
[zupo]Fixed the Flash window mode so that Plone dropdown menus are visible
on top of the Flash movie.
[dokai]Updated the Flash movie to a new version. Highlights:No more empty frames on walls.The default position when entering a room shows the middle box
with the room number better.Redundant tooltips (prev, next, forward, backward, etc) removed.Traversal through doors using mouse clicks.Repositioned the prev/next and fullscreen buttons.Fixed a bug with image info popups being sticky in fullscreen mode.Fixed a bug with empty galleries.Fixed a bug with tooltips not expanding correctly over different
sized text.Fixed a bug where in some cases clicking on an image would zoom-in
on a wrong one.Traversing through doors is possible with a single click.Removed also the now redundant entries in the JSON configuration.[dokai]1.0b4 (2011-08-10)Really fix the packaging error. The setuptoolsunpack_tarfilefunction
filters out symlinks when unpacking so they will not be present in the
unpacked package. This, combined with some weirdness in eithertaritself or the Python tar module which reverses the order of the link,
caused the targets of the symlinks to be removed from the final unpacked
package.
[dokai]1.0b3 (2011-08-10)Fixed packaging error in 1.0b2.
[dokai]JSON schema validation.
[zupo]1.0b2 (2011-08-04)Code cleanups.
[zupo]More comments and documentation.
[zupo]More tests.
[zupo]1.0b1 (2011-08-04)Initial release.
