Linux kernel. The software is available in 8 languages and 2 variants: English, French, Canadian French, Japanese, German, Dutch, Italian, Spanish, Portuguese, and Brazilian Portuguese. The main application, the digital reader, supports a variety of ebook formats:
ePub,
PDF, Adobe DRM,
RTF,
HTML,
TXT,
Comic Book Archive file,
JPEG,
PNG,
BMP,
GIF, and
TIFF. By flicking or tapping a side of the screen, the user may advance to the next page or previous page. Highlighting, adding notes, and looking up definitions in the built-in dictionaries is also possible by long-tapping a passage in any part of the book. Adjusting the font is possible with a feature called TypeGenius: users can change the weight, sharpness, and font size of any preinstalled fonts on the Kobo. and the
Toronto Public Library. These books with
DRM require authentication from
Adobe in order to be read on the device. Books may be added to the device with the Kobo Desktop app or third party apps such as
Calibre. Seven applications are included with the Kobo Aura: a web browser, sudoku, chess (removed from the latest update), Unblock it, Word Scramble,
Solitaire, and a sketch pad. The web browser allows for downloading of files that can be read on the device. Kobo does not provide technical support for these applications. == Reception ==
