# -*- coding: iso-8859-1 -*- """ 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. CALLING SEQUENCE: {{{ #!Gallery2 [columns=columns],[filter=filter],[mode=mode], [show_text=show_text],[show_date=show_date], [show_tools=show_tools], [sort_by_name=sort_by_name],[sort_by_date=sort_by_date], [sort_by_alias=sort_by_alias], [reverse_sort=reverse_sort], [only_items=only_items],[template_itemlist=template_itemlist], [album=album],[album_name=album_name],[front_image=front_image], [thumbnail_width=thumbnail_width],[webnail_width=webnail_width],[text_width=text_width], [image_for_webnail=image_for_webnail], [border_thick=border_thick],[renew=renew],[help=help] * [image1.jpg alias] * [image2.jpg alias] }}} KEYWORD PARAMETERS: columns: number of columns for thumbnails filter: regex to select images show_text: default is 1 description is shown any other means no description show_date: default is 1 date info from exif header if available is shown show_tools: default is 1 icon toolbar is show any other disables this sort_by_name: default is 1, the images are sorted by name, but not if only_items is 1 sort_by_date: default is 0, if set to 1 the images are sorted to the modification time 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 reverse_sort: default is 0, if set to 1 the file list is reversed any other means no description mode: default is 1 this means description below the image any other number means description right of image only_items: default is 0 if it is set to 1 only images which are described in listitem are shown dependend on the order of the items template_itemlist: default is 0, if set to 1 an item list is shown which could be copied into the script. album: default is 0 if set to 1 only the first image of a series is shown but slideshow over all images album_name: useful for album. default is 'album' use it as short name for the album. front_image: Useful for album. default is ''. The first image is shown in front of the album and slideshow. If set to an existing image name this is shown in front of album and slideshow. The slide show could start by this somewhere. border_thick: default is 1 this is the thickness in pixeln of the outer frame renew: default is 0 if set to 1 then all selected thumbnails_* and webnails_* removed. Afterwards they are new created. thumbnail_width: default is 128 webnail_width: default is 640 text_width: default is 140 image_for_webnail default is 0 if set to 1 then the image is shown as preview and not the webnail help: default is 0 if set a copy of the CALLING SEQUENCE is shown, (there are some new ideas around to show help to an user so this will be later replaced) OPTIONAL INPUTS: itemlist : if it is used and only_items is 1 then only the images in this list are ahown. The alias text is used as description of the image instead of the file name EXAMPLE: = GalleryTest = == all images shown, one is decribed == {{{ { { { #!Gallery2 * [100_1185.JPG Bremen, SpaceCenter] } } } }}} Result: [[BR]] {{{ #!Gallery2 * [100_1185.JPG Bremen, SpaceCenter] }}} == only thumbnails and only_items == {{{ { { { #!Gallery2 show_text=0,show_tools=0,show_date=0,columns=2,only_items=1 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen] } } } }}} Result: [[BR]] {{{ #!Gallery2 show_text=0,show_tools=0,show_date=0,columns=2,only_items=1 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen] }}} == only_items by two columns and text right == {{{ { { { #!Gallery2 mode=2,columns=2,only_items=1 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen] } } } }}} Result: [[BR]] {{{ #!Gallery2 mode=2,columns=2,only_items=1 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen, behind SpaceCenter] }}} ---- == only_items by two columns, date supressed == {{{ { { { #!Gallery2 columns=2,only_items=1,show_date=0 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen, behind SpaceCenter] } } } }}} Result: [[BR]] {{{ #!Gallery2 columns=2,only_items=1,show_date=0 * [100_1185.JPG Bremen, SpaceCenter] * [100_1194.JPG Bremen, behind SpaceCenter] }}} == filter regex used, mode 2, icons and date supressed, one column and border_thick=5 == {{{ { { { #!Gallery2 columns=1,filter=100_118[0-5],mode=2,show_date=0,show_tools=0,border_thick=5 } } } }}} Result: [[BR]] {{{ #!Gallery2 columns=1,filter=100_118[0-7],mode=2,show_date=0,show_tools=0,border_thick=5 }}} == other macro calls == {{{ { { { #!Gallery2 only_items=1,show_date=0 * [100_1189.JPG [[MiniPage(||Bremen||SpaceCenter||\n|| ||SpaceJump||)]]] } } } }}} Result: [[BR]] {{{ #!Gallery2 only_items=1,show_date=0 * [100_1189.JPG [[MiniPage(||Bremen||SpaceCenter||\n|| ||SpaceJump||)]]] }}} == renew means always new thumbnails and webnails of selection == {{{ { { { #!Gallery2 only_items=1,show_date=0,show_tools=0,renew=1 * [100_1189.JPG [[MiniPage(||["Bremen"]||SpaceCenter||\n|| ||SpaceJump||)]]] } } } }}} Result: [[BR]] {{{ #!Gallery2 only_items=1,show_date=0,renew=1 * [100_1189.JPG [[MiniPage(||["Bremen"]||SpaceCenter||\n|| ||SpaceJump||)]]] }}} == template_itemlist == {{{ { { { #!Gallery2 template_itemlist=1 * [100_1185.JPG Bremen, SpaceCenter] } } } }}} Result: [[BR]] {{{ #!Gallery2 template_itemlist=1 * [100_1185.JPG Bremen, SpaceCenter] }}} == help to show Calling Sequence == {{{ { { { #!Gallery2 help=1 } } } }}} Result: [[BR]] {{{ #!Gallery2 help=1 }}} PROCEDURE: Download some images to a page and start with the examples. Aliasing of the filenames are done by adding an itemlist, see example. This routine requires the PIL (Python Imaging Library). And the EXIF routine from http://home.cfl.rr.com/genecash/digital_camera.html At the moment I have added the EXIF routine to the parsers dir. It's not the best place but during developing it is nice to have it there If you put it to another place you have to change the line from MoinMoin.parser import EXIF too. This routine requires the Action macro gallery2Image which is used to rotate or delete a selected image. 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. The gallery2image macro does not take care on the EXIF header. This is lost by rotating. If a file is deleted by this macro it is moved to a bak file. Please remove the Version number from the code! RESTRICTIONS: The movie mode is not implemented at the moment. The implementation will be done in the action macro. 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.

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 MODIFICATION HISTORY: Version 1.3.3.-1 @copyright: 2005 by Reimar Bauer (R.Bauer@fz-juelich.de) @license: GNU GPL, see COPYING for details. 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 extra frame by mode=2 removed 2005-08-06: Version 1.3.5-6 slideshow mode added keyword image_for_webnail added 2005-08-13: Version 1.3.5-7 syntax changed from GET to POST 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 2005-08-14: Version 1.3.5-9 html code for tables changed because of the ugly extra space of form elements 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 2005-08-17: Version 1.3.5-10 html code separated in functions structure of code changed, now you see the thumbnails after creation bug removed if quote is given but file does not exist 2005-09-02: Version 1.3.5-11 keyword album, album_name and front_image added image urls changed to complete server url 2005-11-12: Version 1.3.5-12 bug fixed for image_for_webnail=1,renew=1 bug fixed at last cell table end instead of bug fixed don't render a filename as WikiName bug fixed " is allowed in alias name bug fixed ' is allowed in alias name bug fixed linebreak by a space in alias not quite a bug but makes it very difficult to code in gallery2image so additional id removed in alias name """ Dependencies = [] from MoinMoin.action import AttachFile from MoinMoin import wikiutil, config from MoinMoin.Page import Page import os,string,re,Image,StringIO from MoinMoin.parser import EXIF from MoinMoin.parser import wiki def show_tools_restricted(pagename,this_target,thumbnail_width,full,alias,target,exif_date,request): if request.user.may.delete(pagename): return tools_restricted_html(pagename,this_target,thumbnail_width,full,alias,target,exif_date,request) else: return '' def tools_restricted_html(pagename,this_target,thumbnail_width,full,alias,target,exif_date,request): text='''
