   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.

  29         filter:            regex to select images
  30         show_text:         default is 1 description is shown
  31                            any other means no description
  32         show_date:         default is 1 date info from exif header if available is shown

  34         sort_by_name:      default is 1, the images are sorted by name, but not if only_items is 1
  35         sort_by_date:      default is 0, if set to 1 the images are sorted to the modification time
  36         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
  37         reverse_sort:      default is 0, if set to 1 the file list is reversed
  38                            any other means no description
  39         mode:              default is 1 this means description below the image
  40                            any other number means description right of image
  41         only_items:        default is 0 if it is set to 1 only images which are described in listitem are shown
  42                            dependend on the order of the items
  43         template_itemlist: default is 0, if set to 1 an item list is shown which could be copied into the script. 
  44         album:             default is 0 if set to 1 only the first image of a series is shown but slideshow over all images 
  45         album_name:        useful for album. default is 'album' use it as short name for the album. 
  46         front_image:       Useful for album.  default is ''. The first image is shown in front of the album and slideshow.
  47                            If set to an existing image name this is shown in front of album and slideshow. 
  48                            The slide show could start by this somewhere.
  49         border_thick:      default is 1 this is the thickness in pixeln of the outer frame
  50         renew:             default is 0 if set to 1 then all selected thumbnails_* and webnails_* removed.
  51                            Afterwards they are new created.
  52         thumbnail_width:   default is 128
  53         webnail_width:     default is 640
  54         text_width:        default is 140		   
  55         image_for_webnail  default is 0 if set to 1 then the image is shown as preview and not the webnail
  56         help:              default is 0 if set a copy of the CALLING SEQUENCE is shown, 
  57                            (there are some new ideas around to show help to an user so this will be later replaced)
  58         sequence_name:     (ONLY POSIX) default is ''  if set this name is used for an image 
  59                            sequence with an duration of one image per second.
  60                            While for gif and png files the fli format is used a mpg file is created for jpegs.
  61                            For more info see the description on PROCEDURE below
  62                            Because mpeg creation could be take much cpu time this is done as background process. 
  63         sequence_type:     (ONLY POSIX) default is '' by this for png/gif fli format and the original image is used
  64                            and for jpg the mpeg format and the webnails are used. It could be set to fli or mpg. 
  65                            If it is set to mpg then always the original images are used.
  66                            mpg creation takes much more time and the file could be much bigger as a standard fli file      
  67                                                       
  68 
  69     OPTIONAL INPUTS:
  70         itemlist : if it is used and only_items is 1 then only the images in this list are ahown.
  71                    The alias text is used as description of the image instead of the file name

 211     PROCEDURE:
 212     
 213       HOWTO:
 214       Download some images to a page and start with the examples.
 215       Aliasing/Description of the filenames are done by adding an itemlist, see example.
 216 
 217       NEEDS:
 218       This routine requires the Action macro gallery2Image which is used to rotate or delete a
 219       selected image. The actual version is gallery2image-1.3.5-10.py.
 220       Only users which have the rights to delete are able to execute this action macro. 
 221       The icons of these are only shown if you have enough rights. 
 222       Furthermore it requires:
 223        * the PIL (Python Imaging Library).
 224        * the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html
 225       
 226       and on POSIX systems optional:
 227        * ppm2fli: see  http://vento.pi.tu-berlin.de/fli.html
 228        * jpeg2mpeg: see http://www.stillhq.com/jpeg2mpeg
 229 
 230       At the moment I have added the EXIF routine to the parsers dir.
 231       It's not the best place but during developing it is nice to have it there
 232       If you put it to another place you have to change the line
 233       from MoinMoin.parser import EXIF too.
 234 
 235       The gallery2image macro does not take care on the EXIF header. This is lost by rotating.
 236       If a file is deleted by this macro it is moved to a bak file.
 237       
 238       ABOUT FLI/MPG:
 239       The sequence feature is at the moment only for servers using posix platforms available. 
 240       If one has an idea how to do it on other platforms I like to implement it.
 241       
 242       Sometimes people want to have the image sequence in one file playable without internet.
 243       Scientific data could be best animated by the common flc/fli format which was
 244       introduced by autodesk.
 245       If png/gif files are used fli output is generated. 
 246       These files could be played by quicktime, mplayer, xanim and several others
 247       For additional informations on this format look at:
 248       http://woodshole.er.usgs.gov/operations/modeling/flc.html
 249       http://vento.pi.tu-berlin.de/fli.html
 250       The largest X and largest Y dimension is used and the images are centered to these.
 251       The maximum size is 1280x1024 for this format so it is scaled to this if the images are larger
 252       It is not the best for true color images if they have very different color tables.
 253       Creating a sequence in this format does not take much cpu time while it could be very 
 254       long time for a mpg file.
 255                           
 256       If the parameter sequnece_name is used with jpg then the webnails of the images are used, 
 257       because they are normally in a size defined  viewable on screen. 
 258       The files are written into a mpg file using these libraries:
 259       Follow this inforamtion for installation at http://www.stillhq.com/jpeg2mpeg
 260       Because mpeg creation with a duration of 1 second does take a lot of cpu time this is 
 261       done as background process
 262       You have to take care yourself on equal dimensions of all images in a sequence of jpg files
 263       
 264       If you don't like the defaults you could ommit them by using the sequence_type parameter.
 265       By this it is possible to write fli files from jpg or mpg files from png/gif files. 
 266       Always if choosen the original images are used for mpg creation. 
 267       But if they are larger as 1280x1024 they are scaled down
 268       Probably you could got poor quality if you try mpg for png/gif files.
 269       The resize mechanism is not used for jpg files by this parameter the original files ae used.
 270       
 271       
 272       It does not go well if you mix up in a call png, gif and jpg files.
 273       
 274       GENERAL:
 275       Please remove the Version number from the code!
 276       
 277       If you want to upload many files at once please look on MoinMoin versions less 1.5.0
 278       at FeatureRequests/UploadMultipleAttachmentFiles/RulesForUnzip
 279 
 280     RESTRICTIONS:
 281       The movie mode is at the moment implemented for POSIX only.  
 282       As soon as  I know how to do it on other platforms I like to add it
 283       If you rotate an image at the moment the exif is destroyed. PIL ignores the exif header.
 284       This is not a quite big problem normally files with an EXIF header are right rotated.
 285 
 286     Required Images:
 287       I have put them to wiki/modern/img/ dir. The icons were created by me. License: GPL

 295     HISTORY:
 296     While recognizing how to write MiniPage I got the idea to write a Gallery Parser.
 297     We have used in our wikis in the past the Gallery macro of SimonRyan.
 298     I have tried to modify it a bit to change it for 1.3 but my python skills weren't enough
 299     or it was easier to write it completly new.
 300     So this one shows now a way how a Gallery could be used by the parser and an action Macro.
 301     Probably it is a good example for others who like to know how to do this
 302 
 303     MODIFICATION HISTORY:
 304         Version 1.3.3.-1
 305         @copyright: 2005 by Reimar Bauer (R.Bauer@fz-juelich.de)

 308                     creation of thumbnails and webnails in two calls splitted
 309                     Version 1.3.3-3 bug fixed if itemlist is given to describe only some of the images
 310                                     but only_items is not set to 1
 311                                     Example code changed
 312         2005-03-27: Version 1.3.3-4 Action macro added and the form to call it. User which have rights to delete
 313                                     could use the functions of gallery2Image.
 314         2005-08-03: Version 1.3.3-5 theme path for icons corrected and a platform independent path joining
 315                                     os.unlink removed as suggested by CraigJohnson
 316                                     sort_by_name is default if not only_items is 1

 324                                     forms instead of links
 325                                     filenames from images submitted to gallery2image too
 326                                     new keyword sort_by_alias
 327                                     internal code clean up
 328                                     this version needs: gallery2image-1.3.5-5.py
 329         2005-08-14: Version 1.3.5-8 (TW) cleanup

 332                                     div tag removed so now we use the page style
 333                                     slide show action goes to right webnail now
 334                                     this version needs: gallery2image-1.3.5-5.py
 335        2005-08-17: Version 1.3.5-10 html code separated in functions
