 ====== Tumbler ====== ====== Tumbler ======
 +The Tumbler package contains a D-Bus thumbnailing service based on the thumbnail management D-Bus specification. This is useful for generating thumbnail images of files. ​
 +===== Configuration =====
 +Tumbler has since version 0.1.27 a configuration file to control the priority, locations and file sizes the plugin is used for: [[http://​git.xfce.org/​xfce/​tumbler/​plain/​tumblerd/​tumbler.rc|tumbler.rc]].
 +To override the default configuration,​ located in one of the xdg directories on your system, you can copy the rc-file to your ''​$XDG_CONFIG_HOME''​ directory.
 +NB: ''​$XDG_CONFIG_HOME''​ defaults to ''​~/​.config''​.
 +  mkdir -p $XDG_CONFIG_HOME/​tumbler
 +  cp /​etc/​xdg/​tumbler/​tumbler.rc $XDG_CONFIG_HOME/​tumbler/​
 +Each group in the configuration file is responsible for the settings of a particular thumbnailer plugin. The following keys can be used to adjust a plugin:
 +? Disabled
 +! Disable the plugin, the values ''​true''​ and ''​false''​ are accepted.
 +? Priority
 +! Numeric value to control the priority of the plugin. If 2 plugins can provide thumbnails for the same scheme + mime-type combination,​ the plugin with the highest priority is used first.
 +? Locations
 +! A ;-separated path list the plugin will be used for. If the source file is not a child of one of the locations, the plugin won't be used and another plugin with a lower priority will be tried. Absolute paths, environment variables, ~/ and ~username/ are allowed. Leave empty to allow all locations.
 +? MaxFileSize
 +! Maximum size of the source file the plugin will still try to generate a plugin for. The size is in bytes, 0 disabled the check.
 ===== Cover Thumbnailer ===== ===== Cover Thumbnailer =====
 By the default the cover thumbnailer is disabled. The reason is that it sends information (movie title extracted from the filename) to online services to retrieve a poster. This information is normally harmless, but it is private, so therefore it's not enabled by default. By the default the cover thumbnailer is disabled.

-In order to use the cover thumbnailer you need to create a config ​file to white-list locations. If the thumbnail file is a child of one of the locations, it will try to download a poster.+In order to use the cover thumbnailer you need to copy the tumbler.rc ​file to your home directory as described above and set the ''​Disabled''​ key to ''​false''​. It is also advisable to set the Locations path to the directory where you store your movies.
-<file plain ~/​.config/​tumbler/​cover.rc>​ +  ​[CoverThumbnailer
-[General+  ​Disabled=false

 +  MaxFileSize=0 
 +  #​APIKey=your-api-key-from-themoviedb.org
-[TheMovieDB] +The movie thumbnailer supports two different movie APIs. By default, the [[http://​omdbapi.com|The Open Movie Database API]] is used. You can also choose to use [[http://​themoviedb.org|The Movie DB]], but this site requires an API key which you have to [[http://​docs.themoviedb.apiary.io/​|request]] or uh... [[https://​raw.github.com/​xbmc/​xbmc/​master/​addons/​metadata.themoviedb.org/​tmdb.xml|search]].\\ 
-API key to use themoviedb.org ​information +The advantage of the latter is that their database has better support for internationalized movie names. 
 +After creating the rc file, it is best to log off and on again to restart Thunar and Tumbler, because both applications cache the mime-type combinations. 
 +===== Customized Thumbnailers ===== 
 +As of version 0.2.0, the desktop thumbnailer functionality has been added back into tumbler. This functionality supports custom .thumbailer files placed in the /​usr/​share/​thumbnailers folder. 
 +==== Customized Thumbnailer for .dds files ==== 
 +For example, to create a custom thumbnailer for .dds files, do the following:​ 
 +  ​Create the appropriate .thumbnailer file:<​file txt /​usr/​share/​thumbnailers/​dds.thumbnailer>​ 
 +[Thumbnailer Entry] 
 +Name=dds Thumbnailer 
 +Exec=/​usr/​bin/​convert -thumbnail %s %i %o
 </​file>​ </​file>​
 +  - Ensure that a dds mimetype exists in your system (you can view mimetypes with the Xfce4 Mime Type Editor). If it does not exist, create the necessary mime file:<​file txt ~/​.local/​share/​mime/​packages/​dds.xml><?​xml version="​1.0"​ encoding="​UTF-8"?>​
 +<​mime-info xmlns="​http://​www.freedesktop.org/​standards/​shared-mime-info">​
 +    <​mime-type type="​image/​x-dds">​
 +        <​comment>​dds file</​comment>​
 +        <icon name="​image"/>​
 +        <​glob-deleteall/>​
 +        <glob pattern="​*.dds"/>​
 +    </​mime-type>​
 +</​mime-info></​file>​...and run "​update-mime-database ~/​.local/​share/​mime"​.
-The cover thumbnailer ​supports two different API backends+==== Customized Thumbnailer for folders ==== 
-  ​* ​[[http://omdbapi.com]]\\ The //Open Movie Database API//. The used posters are most of the time retrieved from IMDBThis backend ​is used by default+ 
-  * [[http://themoviedb.org]]\\ A free and community maintained movie databaseThis API however requires an API key.+Another example are albums ​cover thumbnails for folders in a music collection. Starting with thunar 1.8.2 a custom ​thumbnailer ​can be added to e.g. add a file  ''​folder.jpg''​ or ''​cover.jpg''​ into a folder and display its thumbnail instead of the default folder icon
 +<file txt /​usr/​share/​thumbnailers/​folder.thumbnailer>​ 
 +[Thumbnailer Entry] 
 +Name=Folder Thumbnailer 
 +Exec=/​usr/​bin/​folder-thumbnailer %s %i %o %u 
 +In order to support different names for the picture-file and to remove the thumbnail if not needed any more (display the default folder icon) , a separate script is required: 
 +<file sh /usr/​bin/​folder-thumbnailer>​ 
 +convert -thumbnail "​$1"​ "$2/folder.jpg" "​$3"​ 1>/​dev/​null 2>&1 ||\ 
 +convert -thumbnail "​$1"​ "​$2/​.folder.jpg"​ "​$3"​ 1>/​dev/​null 2>&1 ||\ 
 +convert -thumbnail "​$1"​ "$2/folder.png"​ "​$3"​ 1>/dev/null 2>&1 ||\ 
 +convert -thumbnail "​$1"​ "$2/cover.jpg" "​$3"​ 1>/​dev/​null 2>&1 ||\ 
 +rm -f "​$HOME/​.cache/​thumbnails/​normal/​$(echo -n "​$4"​ | md5sum | cut -d " " -f1).png"​ ||\ 
 +rm -f "​$HOME/​.thumbnails/​normal/​$(echo -n "​$4"​ | md5sum | cut -d " " -f1).png"​ ||\ 
 +rm -f "​$HOME/​.cache/​thumbnails/​large/​$(echo -n "​$4"​ | md5sum | cut -d " " -f1).png"​ ||\ 
 +rm -f "​$HOME/​.thumbnails/​large/​$(echo -n "​$4"​ | md5sum | cut -d " " -f1).png"​ ||\ 
 +exit 1 
 +Dont forget to give execution permission to the file! E.g: sudo chmod a+x /​usr/​bin/​folder-thumbnailer 
 +Note: imagemagick ​is a required dependency for this script
 +==== Customized Thumbnailer for text-based documents ==== 
 +A thumbnailer for text-based documents can be created using the convert function from the imagemagick package with the following thumbnailer file: 
 +<file txt /usr/share/​thumbnailers/​text.thumbnailer>​ 
 +[Thumbnailer Entry] 
 +Name=Text Thumbnailer 
 +Exec=/​usr/​local/​bin/​textthumb %s %i %o 
 +And supporting script: 
 +<file sh /​usr/​local/​bin/​textthumb>​ 
 +unset iFile 
 +echo "​${iChopped}"​ > tmp.txt 
 +unset iChopped 
 +convert -size 210x290 -background white -pointsize 5 -border 10x10 -bordercolor "#​CCC"​ caption:​@"​tmp.txt"​ "​$3"​ 
 +rm tmp.txt 
-After creating ​the rc file, it is best if you log-off and on again to restart Thunar and Tumbler, because both cache the mime-type combinations.+You can add additional mime types to the MimeType line of the thumbnailer ​file to support additional text-based document types.
