 Keep in mind the potential of the Tox sticker pack to become an open sticker format usable by all free software, like the KDE emoticon packs used by qTox. Keep in mind the potential of the Tox sticker pack to become an open sticker format usable by all free software, like the KDE emoticon packs used by qTox.
  
-==== File Structure ====+==== Sending ====
  
-    ~/.config/tox/stickers/+Once a sticker is selected by the user, it should be sent as a file transfer of TOX_FILE_KIND_STICKER with the name being a hash of its <del>content</del> <del>path</del> <del>name</del> something. //Discussion needed.// 
 + 
 +==== Receiving ==== 
 + 
 +When a client receives a sticker file transfer request, it first checks if that hash is already in the [[stickers#cache|cache]]. If it is, the file transfer is denied and the cached sticker is used instead. This mechanism addresses bandwidth concerns on mobile devices. 
 + 
 +==== Storage ==== 
 + 
 +=== Packs === 
 + 
 +A Sticker Pack is a zipped folder containing stickers, an about.txt, and a pack.png/svg/etc. The Sticker Packs are what appear in the client's sticker-sending popup. This is the user's collection of stickers. Sticker filenames end with numbers, according to the order they should be displayed in.

          `--sticker_3.png          `--sticker_3.png
 +         
 +The file about.txt contains information about the pack. //Should we make it an ini and do real metadata or nah?//
 +
 +The file pack.png/svg/etc is an image used as the thumbnail of the pack as displayed in the client's sticker popup.
 +
 +=== Cache ===
 +
 +The Sticker Cache is a directory that contains all received stickers, stored flatly.
 +
 +    ~/.config/tox/stickers/cache/
 +     |
 +     |--hash.svg
 +     |--hash.png
 +     |--hash.gif
 +     `--hash.svg
 +     
 +//It would be neat to prune/retain stickers from the cache based on how often they're received  //
 +
 +=== Getting ===
 +
 +When a user opts to download a sticker pack from a friend, a file transfer should be initiated and the sticker pack should be automatically saved to the correct location.
