    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.
        Optional you could get a flash animation of the selected images.

    CALLING SEQUENCE:

    PROCEDURE:
      ABOUT:
      While I have first implemented Gallery2 for something like photos I do use it at work since a while for 
      output of model calculations too. 
      Because of the possibility to share a standalone playable file to colleagues I have first decided to use 
      fli or mpeg as output format for an image sequence. mpeg is not quite good for displaying our data 
      and fli does sometimes eat a lot of cpu power. Both would make a lot of work getting them working 
      on a non posix OS. For further development it would be better to have a python only version of Gallery2.
      That's the reason why I switch the sequence format to flash now. I do use the library of Matthias Kramm 
      (http://www.swftools.org). 
    
      HOWTO:
      Download some images to a page and start with the examples.
      Aliasing/Description of the filenames are done by adding an itemlist, see example.

      NEEDS:
      This routine requires the action macro gallery2image which is used to rotate or delete a
      selected image. The actual version is gallery2image-1.3.5-11.py.
      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. 
      Furthermore it requires these python libraries:
       * the PIL (Python Imaging Library).
       * the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html
       * the SWF library from http://www.swftools.org
       
      Do install them to the usual python library path. 
      
      GENERAL:
      Please remove the Version number from the code!
      
      If you want to upload many files at once please look on MoinMoin versions less 1.5.0
      at FeatureRequests/UploadMultipleAttachmentFiles/RulesForUnzip

    RESTRICTIONS:
      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

    attachment:to_bak.png
    attachment:to_left.png
    attachment:to_right.png
    attachment:to_slide.png
    attachment:to_full.png
    
    gallery2image needs from version 1.3.5-6 these images saved to /wiki/modern/img/

    attachment:back.png attachment:first_disabled.png attachment:first.png attachment:last_disabled.png attachment:last.png attachment:next_disabled.png attachment:next.png attachment:previous_disabled.png attachment:previous.png

    One of my colleagues searched for some more /ModernImages 
    
    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
    
    OUTLOOK:
    Dependent on Matthias Kramm's python interface development the webnails could be exchanged to a 
    flash animation with action controls. That will ommit the javascript slide show and will give less files.
    swftools is able to do this by now but that will need an os.system call. At the moment I like to avoid this.
    If you are interested the command is swfcombine -o output.swf movie_control.swf viewport=input.swf. 
    It is still in the code but commented off. movie_control.swf embbeds the controls 24 pixels above the flash so it's a good idea to 
    resize the flash by the -X and -Y option. 
    

    MODIFICATION HISTORY:
        Version 1.3.3.-1
        @copyright: 2005 by Reimar Bauer (R.Bauer@fz-juelich.de)

        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

                                    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

                                    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

                                    not quite a bug but makes it very difficult to code in 
                                    gallery2image so additional id removed in alias name
      2005-11-17: Version 1.3.5-13  implementation of sequence video clips at first step for posix only 
                                    sequence_type could be used to ommit the autoselection

                                    jpeg files. Duration on both is 1 image/second

      2006-01-01: Version 1.3.5-15  only python libs are used in this version
                                    flash (swf) format is used as sequence format
