 +===== Customized Thumbnailers ===== 
 +As of version 0.2.0, the desktop thumbnailer functionality has been added back into tumbler. This functionality supports custom .thumbnailer 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: For example, to create a custom thumbnailer for .dds files, do the following:
Line 65: Line 103:
     </mime-type>     </mime-type>
 </mime-info></file>...and run "update-mime-database ~/.local/share/mime". </mime-info></file>...and run "update-mime-database ~/.local/share/mime".
 +
 +==== Customized Thumbnailer for folders ====
 +
 +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]
 +Version=1.0
 +Encoding=UTF-8
 +Type=X-Thumbnailer
 +Name=Folder Thumbnailer
 +MimeType=inode/directory;
 +Exec=/usr/bin/folder-thumbnailer %s %i %o %u
 +</file>
 +
 +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>
 +#!/bin/bash
 +
 +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 "$4" | md5sum | cut -d " " -f1).png" ||\
 +exit 1
 +</file>
 +
 +Dont forget to give execution permission to the file! E.g: sudo chmod a+x /usr/bin/folder-thumbnailer
 +
 +Note: imagemagick is a required dependency for this script.
 +
 +==== Customized Thumbnailer for text-based documents ====
 +A thumbnailer for text-based documents can be created using the convert function from the imagemagick package with the following thumbnailer file:
 +
 +<file txt /usr/share/thumbnailers/text.thumbnailer>
 +[Thumbnailer Entry]
 +Version=1.0
 +Encoding=UTF-8
 +Type=X-Thumbnailer
 +Name=Text Thumbnailer
 +MimeType=text/plain;text/html;text/css;
 +Exec=/usr/local/bin/textthumb %s %i %o
 +</file>
 +
 +And supporting script:
 +
 +<file sh /usr/local/bin/textthumb>
 +#!/bin/bash
 +iFile=$(<"$2")
 +iChopped="${iFile:0:1600}"
 +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
 +</file>
 +
 +You can add additional mime types to the MimeType line of the thumbnailer file to support additional text-based document types.
 +
 +==== Customized Thumbnailer for comic book archives ====
 +A thumbnailer for comic book archives (cbr, cbz, cbt, cb7) can be created using the comicthumb utility (search for it your distro's repositories). Use the following thumbnailer file:
 +<file txt /usr/share/thumbnailers/comicthumb.thumbnailer>
 +[Thumbnailer Entry]
 +TryExec=comicthumb
 +Exec=comicthumb %u %o %s
 +MimeType=application/x-cb7;application/x-cbr;application/x-cbt;application/x-cbz;application/x-ext-cb7;
 +application/x-ext-cbr;application/x-ext-cbt;application/x-ext-cbz;application/vnd.comicbook-rar
 +</file>
 +
 +==== Customized Thumbnailer for webp content ====
 +Note: Make sure there is an image/webp mimetype defined in your system.
 +<file txt /usr/share/thumbnailers/webp.thumbnailer>
 +[Thumbnailer Entry]
 +Version=1.0
 +Encoding=UTF-8
 +Type=X-Thumbnailer
 +Name=webp Thumbnailer
 +MimeType=image/webp;
 +Exec=/usr/bin/convert -thumbnail %s %i %o
 +</file>
