   3     MoinMoin - Gallery2 parser
   4 
   5     PURPOSE:
   6         This parser is used to visualize a couple of images as a thumbnail gallery.
   7         Optional a description of an image could be added including WikiName.
   8         On default the image name and it's creation date is shown.
   9         If you click on a thumbnail you get the webnails shown. By a menue you are able to toggle between the slides.
  10 
  11     CALLING SEQUENCE:
  12       {{{
  13       #!Gallery2 [columns=columns],[filter=filter],[mode=mode],

  29         filter:            regex to select images
  30         show_text:         default is 1 description is shown
  31                            any other means no description

  35         sort_by_date:      default is 0, if set to 1 the images are sorted to the modification time
  36                            if they do have all the same time then the result is random
  37         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
  38         reverse_sort:      default is 0, if set to 1 the file list is reversed
  39                            any other means no description
  40         mode:              default is 1 this means description below the image

  42         only_items:        default is 0 if it is set to 1 only images which are described in listitem are shown
  43                            dependend on the order of the items
  44         template_itemlist: default is 0, if set to 1 an item list is shown which could be copied into the script.

  47         front_image:       Useful for album.  default is ''. The first image is shown in front of the album and slideshow.
  48                            If set to an existing image name this is shown in front of album and slideshow. 
  49                            The slide show could start by this somewhere.
  50         border_thick:      default is 1 this is the thickness in pixeln of the outer frame

  58                            sequence with an duration of one image per second.
  59         sequence_fps:      (frames per second) default is 1 it is not allowed to set values below 1
  60         help:              default is 0 if set a copy of the CALLING SEQUENCE is shown, 
  61                            (there are some new ideas around to show help to an user so this will be later replaced)
  62                            
  63 
  64     OPTIONAL INPUTS:
  65         itemlist : if it is used and only_items is 1 then only the images in this list are ahown.
  66                    The alias text is used as description of the image instead of the file name

 206     PROCEDURE:
 207       ABOUT:
 208       While I have first implemented Gallery2 for something like photos I do use it at work since a while for
 209       output of model calculations too.
 210       Because of the possibility to share a standalone playable file to colleagues I have first decided to use
 211       fli or mpeg as output format for an image sequence. mpeg is not quite good for displaying our data
 212       and fli does sometimes eat a lot of cpu power. Both would make a lot of work getting them working
 213       on a non posix OS. For further development it would be better to have a python only version of Gallery2.
 214       That's the reason why I switch the sequence format to flash now. I do use the library of Matthias Kramm
 215       (http://www.swftools.org).
 216       
 217       HOWTO:
 218       Download some images to a page and start with the examples.
 219       Aliasing of the filenames are done by adding an itemlist, see example.
 220 
 221       NEEDS:
 222       This routine requires the Action macro gallery2image which is used to rotate or delete a
 223       selected image. The actual version is gallery2image-1.5.4-13.py.
 224       Only users which have the rights to delete are able to execute this action macro. 
 225       The icons of these are only shown if you have enough rights. 
 226       Furthermore it requires:
 227        * the PIL (Python Imaging Library).
 228        * the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html
 229          (you need a modifed version you'll get it from the Gallery2 documentation page)
 230        * the SWF library from http://www.swftools.org
 231 
 232       Do install them to the usual python library path.
 233       
 234       REQUIRED IMAGES:
 235       You have to put them into wiki/mg/ dir. e.g.: http://moinmoin.wikiwikiweb.de/ParserMarket/Gallery2/ModernImages
 236       
 237       GENERAL:
 238       Please remove the Version number from the code!
 239 
 240       If you want to upload many files at once please look on MoinMoin versions less 1.5.0
 241       at FeatureRequests/UploadMultipleAttachmentFiles/RulesForUnzip
 242       
 243       With many images you can get in trouble by the SurgeProtection for attachment. Then you have to adjust the parameters see HelpOnConfiguration/SurgeProtection. 
 244       
 245       RESTRICTIONS:
 246       If you rotate an image at the moment the exif is destroyed. PIL ignores the exif header.
 247       This is not a quite big problem normally files with an EXIF header are right rotated.
 248       
 249       HISTORY:
 250       While recognizing how to write MiniPage I got the idea to write a Gallery Parser.
 251       We have used in our wikis in the past the Gallery macro of SimonRyan.
 252       I have tried to modify it a bit to change it for 1.3 but my python skills weren't enough
 253       or it was easier to write it completly new.
 254       So this one shows now a way how a Gallery could be used by the parser and an action Macro.
 255       Probably it is a good example for others who like to know how to do this
 256 
 257       OUTLOOK:
 258       Dependent on Matthias Kramm's python interface development the webnails could be exchanged to a
 259       flash animation with action controls. That will ommit the javascript slide show and will give less files.
 260       swftools is able to do this by now but that will need an os.system call. At the moment I like to avoid this.
 261       If you are interested the command is swfcombine -o output.swf movie_control.swf viewport=input.swf.
 262       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.

 307                                     not quite a bug but makes it very difficult to code in 
 308                                     gallery2image so additional id removed in alias name
 309       2005-11-17: Version 1.3.5-13  implementation of sequence video clips at first step for posix only 
 310                                     sequence_type could be used to ommit the autoselection
 311                                     fli/flc files are used for gif and png files,  mpeg files for
 312                                     jpeg files. Duration on both is 1 image/second 
 313                                     feature added of recognising the right url pattern (http opr https)

 320                                     use of cfg.url_prefix insted of hard coding /wiki
 321                                          
 322      ReimarBauer:                   PEP8 style
 323                                     mode2 changed to Florians style too
 324                                     some other changes to get things compatible to previous versions
 325                                     flash (swf) format is used as sequence format
 326                                     keyword sequence_fps added
 327                                     keyword eo_info added
 328                                     EXIF.py moved to python lib 
 329                                        used the version of StigIversen
 330                                        
 331                                     file names of webnails and thumbnails does now have a prefix of tmp.   
 332                                     direct serving of webnails and thumbnails is possible but not default
 333                                        You have to set the var document_root in your wikiconfig.py to the absolute path of
 334                                        the wiki alias. For the default installation it is document_root = '/usr/share/moin/htdocs'
 335                                        Using this method MoinMoin can't use acls for the webnails and thumbnails.
 336 
 337     2006-08-11 1.6.0-17 RB ported to 1.6.0 dev alpha version
 338     2006-08-22 1.6.0-18 RB for the call of Frame a test if parameters are submitted is added
 339     2008-02-06 1.6.0-19 RB small fixes disabling SWF on all places if not available, import EXIF from MM.filter
