   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],

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

  34         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
  35         reverse_sort:      default is 0, if set to 1 the file list is reversed
  36                            any other means no description

 194     PROCEDURE:
 195       Download some images to a page and start with the examples.
 196       Aliasing of the filenames are done by adding an itemlist, see example.
 197 
 198       This routine requires the PIL (Python Imaging Library).
 199       And the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html
 200 
 201 
 202       At the moment I have added the EXIF routine to the parsers dir.
 203       It's not the best place but during developing it is nice to have it there
 204       If you put it to another place you have to change the line
 205       from MoinMoin.parser import EXIF too.
 206 
 207       This routine requires the Action macro gallery2Image which is used to rotate or delete a selected image.
 208       Only users which have the rights to delete are able to execute this action macro.
 209       The icons of these are only shown if you have enough rights.
 210 
 211       The gallery2image macro does not take care on the EXIF header. This is lost by rotating.
 212       If a file is deleted by this macro it is moved to a bak file.
 213 
 214       Please remove the Version number from the code!
 215 
 216     RESTRICTIONS:
 217       The movie mode is not implemented at the moment. The implementation will be done in the action macro.
 218       
 219       
 220       If you rotate an image at the moment the exif is destroyed. PIL ignores the exif header.
 221       This is not a quite big problem normally files with an EXIF header are right rotated.
 222 
 223     Required Images:
 224       I have put them to wiki/modern/img/ dir. The icons were created by me. License: GPL

 232     HISTORY:
 233     While recognizing how to write MiniPage I got the idea to write a Gallery Parser.
 234     We have used in our wikis in the past the Gallery macro of SimonRyan.
 235     I have tried to modify it a bit to change it for 1.3 but my python skills weren't enough
 236     or it was easier to write it completly new.
 237     So this one shows now a way how a Gallery could be used by the parser and an action Macro.
 238     Probably it is a good example for others who like to know how to do this
 239 
 240     MODIFICATION HISTORY:
 241         Version 1.3.3.-1
 242         @copyright: 2005 by Reimar Bauer (R.Bauer@fz-juelich.de)
 243         @license: GNU GPL, see COPYING for details.
 244         2005-03-26: Version 1.3.3-2 keyword renew added
 245                     creation of thumbnails and webnails in two calls splitted
 246                     Version 1.3.3-3 bug fixed if itemlist is given to describe only some of the images
 247                                     but only_items is not set to 1
 248                                     Example code changed
 249         2005-03-27: Version 1.3.3-4 Action macro added and the form to call it. User which have rights to delete
 250                                     could use the functions of gallery2Image.
 251         2005-08-03: Version 1.3.3-5 theme path for icons corrected and a platform independent path joining
 252                                     os.unlink removed as suggested by CraigJohnson
 253                                     sort_by_name is default if not only_items is 1
 254                                     optional sort_by_date could be used
 255                                     keyword template_itemlist added 
 256                                     keyword help added
 257                                     extra frame by mode=2 removed 
 258         2005-08-06: Version 1.3.5-6 slideshow mode added
 259                                     keyword image_for_webnail added
 260         2005-08-13: Version 1.3.5-7 syntax changed from GET to POST
 261                                     forms instead of links
 262                                     filenames from images submitted to gallery2image too
 263                                     new keyword sort_by_alias
 264                                     internal code clean up
 265                                     this version needs: gallery2image-1.3.5-5.py
 266         2005-08-14: Version 1.3.5-8 (TW) cleanup                                    
 267         2005-08-14: Version 1.3.5-9 html code for tables changed
 268                                     because of the ugly extra space of form elements
 269                                     </div> tag removed so now we use the page style
 270                                     slide show action goes to right webnail now
 271                                     this version needs: gallery2image-1.3.5-5.py
 272        2005-08-17: Version 1.3.5-10 html code separated in functions     
 273                                     structure of code changed, now you see the thumbnails after creation
 274                                     bug removed if quote is given but file does not exist
 275
