The Own Memory application was created by Petr Voborník from Amporis, s.r.o. with support of the allied company PoVI, s.r.o.

Cutom image sets

You can create custom sets of cards for the game in the app. Either you can use an internal set editor (currently only works with pictures), or you can use the following procedure:

  1. Choose and prepare pictures, eventually files of other types (audio or files with text)
  2. Pack them into the zip archive
  3. Change the file extension from .ZIP to .OMS and launch it

Editor of sets in the app

You can add a custom set directly from the main screen with the overview of the sets. You can also edit any of the imported sets. You can insert images into the set from the library of images on your device. Inserted images are automatically rotated according to EXIF information, cropped on a square, reduced to 512x512 pixels and saved as JPG of 80% quality. If one of these automatic actions does not suit you, you can prepare the image to the final form in any external application or use the feature for import of whole set.

You can export the finished set of images as the single file. You can back up and then re-import this set, copy and import it to another device, send it to your friends, family or even share it publicly. You can also import sets made by someone else.

Images in sets can be arbitrary. For example, you can create a sat of cards with family photos, photos of friends, classmates, leaders, characters from your favorite movies or serials, pictures of buildings, facilities, nature, monuments of the world's major metropolises, etc. You can also focus on images such as traffic signs, chemical elements, portraits of famous writers, actors, presidents, states, vocabulary in foreign language, animals, planets, etc.

Create a set of cards outside the application (only in Czech at now)

The exported card set with extension .OMS is actually a classic ZIP archive, in which the individual files are standardly packaged. You can create a set yourself by hand, without having to use the Own Memory application. A chosen pictures simply packe into the ZIP archive. You do not even need to change the file extension from .ZIP to .OMS because the ZIP file can also be imported. The .OMS extension is linked to the application and can be launched over these files and the import of the cards set will be offered directly.

The archive structure should be free of folders and contain only image files, audio files, or text files (xml). File names can be arbitrary, but you can use other features of the application by choosing this name appropriately. After import, you can delete any image from the set, add new ones or change the image for the back of the cards.

Images in sets imported from files created without application are no longer altered. Their format, dimensions, size and quality are used without any change in the game. However, it is not advisable to insert too large images. If any image does not have a square dimension, the entire card area will not be used to draw it.

Because the ZIP is an open format then cannot be ruled out that someone can also include files with illegal or even malicious content. The application verifies the format of the individual decompressed files while importing, however, you should import only sets from known sources checked by someone trusted, by antivirus or by self-controll of archive content.

Rules for file names in the set

Supported extensions of the files are:

  • Images: JPG, JPEG, PNG
  • Audio files: MP3, WAV
  • Text data: XML

Reserved file names

  • _info.* (data) - information about set (name, description, author, license, url and settings of the play board)
  • _back.* (image/data) - image and/or text data for back of cards of the set (if absents, default background image from the app will be used)
  • _theme.* (image) - image that is used in the sets list
  • _default.* (image/data/audio) - image, audio and/or text data used for cards without image, audio or text data (at least one of these file types must exists for card identification, other may be defaults); if this name has a suffix (e.g. "~a" or "~b", i.e. there are files "_default~a.jpg" and "_default~b.jpg") then these default images (or data or audio) will be linked with cards with the same suffix
  • _turn-card.* (audio) - a sound for turn a card
  • _pair.* (audio) - a default sound when the whole pair is turned
  • _pair~yes.* (audio) - a sound when the pair of the same cards is founded
  • _pair~no.* (audio) - a sound when the pair of a different cards is turned
  • _end.* (audio) - a default sound for the end of the game
  • _end~human.* (audio) - a default sound for the end of the game when human wins over computer
  • _end~computer.* (audio) - a default sound for the end of the game when computer wins over man
  • _end~both.* (audio) - a default sound for the end of the game when computer and man has the same score or when plays computers only

Reserved characters in file names

  • _ (underscore) - underscores at the beginning is reserved for special files (reserved file names, see above)
  • ~ (swung dash) - separator of the different cards in the same pair (e.g. card1~a.jpg and card1~b.jpg is the pair but with diferent images)
  • . (dot) - dot is before file extension, but can be used for separation of the culture code (two chars ISO 639-1) at the end of file name (e.g. if there are card2.en.jpg, card2.es.jpg and card2.jpg files, the first image will be shown only for english localization, second only for spanish and the third for every other languages)

For launch the app Own Memory and import the set by clicking to a web link to a file with set of cards with .OMS extension, is necessery to set MIME type with ".oms" extension to value "application/x-oms" on the web server config.
