    MoinMoin - Gallery2 parser

    PURPOSE:
        This parser is used to visualize a couple of images as a thumbnail gallery.
        Optional a description of an image could be added including WikiName.
        On default the image name and it's creation date is shown.
        If you click on a thumbnail you get the webnails shown. By a menue you are able to toggle between the slides.

    CALLING SEQUENCE:
      {{{
      #!Gallery2 [columns=columns],[filter=filter],[mode=mode],
                 [show_text=show_text],[show_date=show_date], [show_tools=show_tools],

    KEYWORD PARAMETERS:
        columns:           number of columns for thumbnails
        filter:            regex to select images
        show_text:         default is 1 description is shown
                           any other means no description
        show_date:         default is 1 date info from exif header if available is shown
        show_tools:        default is 1 icon toolbar is show any other disables this
        sort_by_name:      default is 1, the images are sorted by name, but not if only_items is 1
        sort_by_date:      default is 0, if set to 1 the images are sorted to the modification time
        sort_by_alias      default is 0, if set to 1 and only_items set to 1 it is used to order the images by the alias name
        reverse_sort:      default is 0, if set to 1 the file list is reversed
                           any other means no description
        mode:              default is 1 this means description below the image
                           any other number means description right of image
        only_items:        default is 0 if it is set to 1 only images which are described in listitem are shown
                           dependend on the order of the items
        template_itemlist: default is 0, if set to 1 an item list is shown which could be copied into the script. 
        album:             default is 0 if set to 1 only the first image of a series is shown but slideshow over all images 
        album_name:        useful for album. default is 'album' use it as short name for the album. 
        front_image:       Useful for album.  default is ''. The first image is shown in front of the album and slideshow.
                           If set to an existing image name this is shown in front of album and slideshow. 
                           The slide show could start by this somewhere.
        border_thick:      default is 1 this is the thickness in pixeln of the outer frame
        renew:             default is 0 if set to 1 then all selected thumbnails_* and webnails_* removed.
                           Afterwards they are new created.
        thumbnail_width:   default is 128
        webnail_width:     default is 640
        text_width:        default is 140		   
        image_for_webnail  default is 0 if set to 1 then the image is shown as preview and not the webnail
        help:              default is 0 if set a copy of the CALLING SEQUENCE is shown, 
                           (there are some new ideas around to show help to an user so this will be later replaced)

    OPTIONAL INPUTS:
        itemlist : if it is used and only_items is 1 then only the images in this list are ahown.
                   The alias text is used as description of the image instead of the file name

    PROCEDURE:
      Download some images to a page and start with the examples.
      Aliasing of the filenames are done by adding an itemlist, see example.

      This routine requires the PIL (Python Imaging Library).
      And the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html


      At the moment I have added the EXIF routine to the parsers dir.
      It's not the best place but during developing it is nice to have it there
      If you put it to another place you have to change the line
      from MoinMoin.parser import EXIF too.

      This routine requires the Action macro gallery2Image which is used to rotate or delete a selected image.
      Only users which have the rights to delete are able to execute this action macro.
      The icons of these are only shown if you have enough rights.

      The gallery2image macro does not take care on the EXIF header. This is lost by rotating.
      If a file is deleted by this macro it is moved to a bak file.

      Please remove the Version number from the code!

    RESTRICTIONS:
      The movie mode is not implemented at the moment. The implementation will be done in the action macro.
      
      
      If you rotate an image at the moment the exif is destroyed. PIL ignores the exif header.
      This is not a quite big problem normally files with an EXIF header are right rotated.

    Required Images:
      I have put them to wiki/modern/img/ dir. The icons were created by me. License: GPL

    HISTORY:
    While recognizing how to write MiniPage I got the idea to write a Gallery Parser.
    We have used in our wikis in the past the Gallery macro of SimonRyan.
    I have tried to modify it a bit to change it for 1.3 but my python skills weren't enough
    or it was easier to write it completly new.
    So this one shows now a way how a Gallery could be used by the parser and an action Macro.
    Probably it is a good example for others who like to know how to do this

    MODIFICATION HISTORY:
        Version 1.3.3.-1
        @copyright: 2005 by Reimar Bauer (R.Bauer@fz-juelich.de)
        @license: GNU GPL, see COPYING for details.
        2005-03-26: Version 1.3.3-2 keyword renew added
                    creation of thumbnails and webnails in two calls splitted
                    Version 1.3.3-3 bug fixed if itemlist is given to describe only some of the images
                                    but only_items is not set to 1
                                    Example code changed
        2005-03-27: Version 1.3.3-4 Action macro added and the form to call it. User which have rights to delete
                                    could use the functions of gallery2Image.
        2005-08-03: Version 1.3.3-5 theme path for icons corrected and a platform independent path joining
                                    os.unlink removed as suggested by CraigJohnson
                                    sort_by_name is default if not only_items is 1
                                    optional sort_by_date could be used
                                    keyword template_itemlist added 
                                    keyword help added
                                    extra frame by mode=2 removed 
        2005-08-06: Version 1.3.5-6 slideshow mode added
                                    keyword image_for_webnail added
        2005-08-13: Version 1.3.5-7 syntax changed from GET to POST
                                    forms instead of links
                                    filenames from images submitted to gallery2image too
                                    new keyword sort_by_alias
                                    internal code clean up
                                    this version needs: gallery2image-1.3.5-5.py
        2005-08-14: Version 1.3.5-8 (TW) cleanup                                    
        2005-08-14: Version 1.3.5-9 html code for tables changed
                                    because of the ugly extra space of form elements
                                    </div> tag removed so now we use the page style
                                    slide show action goes to right webnail now
                                    this version needs: gallery2image-1.3.5-5.py
       2005-08-17: Version 1.3.5-10 html code separated in functions     
                                    structure of code changed, now you see the thumbnails after creation
                                    bug removed if quote is given but file does not exist
       2005-09-02: Version 1.3.5-11 keyword album, album_name and front_image added          
                                    image urls changed to complete server url
