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

 209     PROCEDURE:
 210       ABOUT:
 211       While I have first implemented Gallery2 for something like photos I do use it at work since a while for 
 212       output of model calculations too. 
 213       Because of the possibility to share a standalone playable file to colleagues I have first decided to use 
 214       fli or mpeg as output format for an image sequence. mpeg is not quite good for displaying our data 
 215       and fli does sometimes eat a lot of cpu power. Both would make a lot of work getting them working 
 216       on a non posix OS. For further development it would be better to have a python only version of Gallery2.
 217       That's the reason why I switch the sequence format to flash now. I do use the library of Matthias Kramm 
 218       (http://www.swftools.org). 
 219     
 220       HOWTO:
 221       Download some images to a page and start with the examples.
 222       Aliasing/Description of the filenames are done by adding an itemlist, see example.
 223 
 224       NEEDS:
 225       This routine requires the action macro gallery2image which is used to rotate or delete a
 226       selected image. The actual version is gallery2image-1.3.5-11.py.
 227       Only users which have the rights to delete are able to execute this action macro. 
 228       The icons of these are only shown if you have enough rights. 
 229       Furthermore it requires these python libraries:
 230        * the PIL (Python Imaging Library).
 231        * the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html
 232        * the SWF library from http://www.swftools.org
 233        
 234       Do install them to the usual python library path. 
 235       
 236       GENERAL:
 237       Please remove the Version number from the code!
 238       
 239       If you want to upload many files at once please look on MoinMoin versions less 1.5.0
 240       at FeatureRequests/UploadMultipleAttachmentFiles/RulesForUnzip
 241 
 242     RESTRICTIONS:
 243       If you rotate an image at the moment the exif is destroyed. PIL ignores the exif header.
 244       This is not a quite big problem normally files with an EXIF header are right rotated.
 245 
 246     REQUIRED IMAGES:
 247       I have put them to wiki/modern/img/ dir. The icons were created by me. License: GPL

 260     
 261     HISTORY:
 262     While recognizing how to write MiniPage I got the idea to write a Gallery Parser.
 263     We have used in our wikis in the past the Gallery macro of SimonRyan.
 264     I have tried to modify it a bit to change it for 1.3 but my python skills weren't enough
 265     or it was easier to write it completly new.
 266     So this one shows now a way how a Gallery could be used by the parser and an action Macro.
 267     Probably it is a good example for others who like to know how to do this
 268     
 269     OUTLOOK:
 270     Dependent on Matthias Kramm's python interface development the webnails could be exchanged to a 
 271     flash animation with action controls. That will ommit the javascript slide show and will give less files.
 272     swftools is able to do this by now but that will need an os.system call. At the moment I like to avoid this.
 273     If you are interested the command is swfcombine -o output.swf movie_control.swf viewport=input.swf. 
 274     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 
 275     resize the flash by the -X and -Y option. 
 276

 278     MODIFICATION HISTORY:

 283                     creation of thumbnails and webnails in two calls splitted
 284                     Version 1.3.3-3 bug fixed if itemlist is given to describe only some of the images
 285                                     but only_items is not set to 1
 286                                     Example code changed
 287         2005-03-27: Version 1.3.3-4 Action macro added and the form to call it. User which have rights to delete
 288                                     could use the functions of gallery2Image.
 289         2005-08-03: Version 1.3.3-5 theme path for icons corrected and a platform independent path joining
 290                                     os.unlink removed as suggested by CraigJohnson
 291                                     sort_by_name is default if not only_items is 1

 302                                     internal code clean up
 303                                     this version needs: gallery2image-1.3.5-5.py
 304         2005-08-14: Version 1.3.5-8 (TW) cleanup                                    
 305         2005-08-14: Version 1.3.5-9 html code for tables changed
 306                                     because of the ugly extra space of form elements
 307                                     div tag removed so now we use the page style
 308                                     slide show action goes to right webnail now
 309                                     this version needs: gallery2image-1.3.5-5.py
 310        2005-08-17: Version 1.3.5-10 html code separated in functions     
 311                                     structure of code changed, now you see the thumbnails after creation
 312                                     bug removed if quote is given but file does not exist
 313        2005-09-02: Version 1.3.5-11 keyword album, album_name and front_image added

 320                                     bug fixed linebreak by a space in alias  
 321                                     not quite a bug but makes it very difficult to code in 
 322                                     gallery2image so additional id removed in alias name
 323       2005-11-17: Version 1.3.5-13  implementation of sequence video clips at first step for posix only 
 324                                     sequence_type could be used to ommit the autoselection
 325                                     fli/flc files are used for gif and png files,  mpeg files for
 326                                     jpeg files. Duration on both is 1 image/second 
 327                                     feature added of recognising the right url pattern (http opr https)
 328       2005-12-03: Version 1.3.5-14  bug fixed of to_slide tools function a wrong mark was used
 329                                     all output of convert or ppm2fli redirected to /dev/null
 330                                     it is not necessary to keep output in the webservers log file
 331       2006-01-01: Version 1.3.5-15  only python libs are used in this version
 332                                     flash (swf) format is used as sequence format 
 333                                     keyword sequence_fps added, keyword sequence_type removed
 334                                     keyword eo_info added
 335                                     EXIF.py moved to python lib
 336                                     var wiki added as supposed
