       archives

        - thumbnails
        - page caching and page preloading
        - ... and more

       QComicBook software requirements:
        -  rar/unrar  (one  of  them),  unzip, unace and tar (with gzip and bzip2 support compiled-in) available
       somewhere in the PATH (e.g. in /usr/bin). If one of them is missing, you  won't  be  able  to  open  some
       archives
        - a lot of disk space available in /tmp directory, for handling decompression of archives

       File

       File menu provies basic operations for loading comic books:
        - Open directory - open directory containg images.
        - Open archive - open archived images.
        -  Recently  opened  -  list  of ten recently opened archives / directories (most recently opened on the
       top).
        - Info - displays information about currenly opened comic book. This includes  contents  of  file_id.diz
       *.nf o files (if any) as well as memory usage info.
        - Settings - allows you to fine-tune some options.
        - Close - closes currently opened comic book.
        - Quit - quits QComicBook.

       QComicBook offers some tunable options, available via Settings menu option. These options include:
        - Background color - the color of the empty area around displayed image.
        -  Hide  menubar in fullscreen mode - menubar may be hidded in fullscreen mode if desired; together with
       toolbar hiding option, it may give you the whole screen for displaying page contents.
        - Hide statusbar in fullscreen mode - statusbar may be hidden in fullscreen mode, giving you  even  more
       space.
        - Small mouse cursor - toggles small (4x4 pixels) mouse cursor for QComicBook window.
        -  Scaling method - the algorithm used for image scaling; either Smooth or Fast. Smooth scaling provides
       best quality, but is slower; it is recommened method unless you have really slow machine.
        - Cache size - the number of pages kept in memory. Value of 0 disables  caching;  1  has  no  effect  on
       performance;  2  or  more  may  improve  your experience. Keep in mind, that caching may consume a lot of
       memory - for example, an 1280x1984 image may take as much as 9Mb of memory!
        - Preload next page - enables page preloading in the background. This  setting  takes  effect  only  for
       cache  size  of  3 and greater. It is recommended to enable this option, as it may really improve overall
       experience.
        - Use disk cache for thumbnails - thumbnails are saved to disk, which speeds up things when loading them
       later. Set this option on if you tend to open comic books more then once.
        -  Number  of days to keep thumbnails - defines, for how long to keep thumbnails on disk; old thumbnails
       are deleted when exiting QComicBook. Value of 0 disables purging.
        - Help browser - allows to choose between simple built-in browser (the default) or  any  other  external
       web browser.
        - Forward and backward two pages in two-pages mode.
        -  Open  info  dialog after opening comic book - when enabled, info dialog is opened after opening comic
       book. You may still open this dialog manually with File/Info menu option.
        - Confirm exit.

       Note: changing cache size takes effect on new comic book.

       View

       View submenu provides some basic settings for page view.

       You can select one of the following scaling modes:
        - Original size - no scaling is done and original image size is preserved.
        - Fit width - image is scaled to fit window width.
        - Fit height - image is scaled to fit window height.
        - Whole page - image is scaled to fit window.
        - Best fit - depending on image dimensions, QComicBook chooses the best method to scale image.

       The page can be rotated with 90 degree step, with these options:
        - Rotate right - rotates image clockwise.
        - Rotate left - rotates image counter clockwise.
        - No rotation - resets rotation, restores original image.
        - Preserve rotation - makes rotation "permanent" for viewing next pages.

       Other options in this menu:
        - Fullscreen - toggles beetween fullscreen and  windowed  mode;  please  note,  that  depending  on  you
       settings,  menubar may be hidden in fullscreen mode, so to back to windowed mode you need to press F11 or
       ESC key.
        - Two pages - display two pages, side by side, just like when reading normal book.
        - Japanese mode - scrolls to top-right corner on page change; in two pages mode additionaly swaps pages.
        - Thumbnails - toggles thumbnails window.

       Settings in this menu are saved when quitting QComicBook (except for "fullscreen" option).

       Bookmarks

       Bookmarks  menu  allows  you  to  bookmark  pages  in  comic  books. These bookmarks are however somewhat
       different than, for example, in any webbrowser and are more similiar to  real  bookmarks.  Each  bookmark
       keeps  bookmarked  page  number (as well as file name), so you can easily start with your comic book from
       the point, where you last stopped reading.

       Two options are available in this menu:
        - Set bookmark for this comicbook - creates bookmark for current comic book; existing bookmark for  this
       comic book is deleted.
        - Remove bookmark for this comicbook - removes existing bookmark for current comic book; to remove other
       bookmarks, use Manage bookmarks option.
        - Manage bookmarks - opens bookmark manager, where bookmarks can be easily removed.

       Below these options you can see the list of currently saved bookmarks. Just click on one of them to go to
       bookmarked comic book and page.

INTERNALS

       Here is some information for people interested in QComicBook internals.

       1. Settings handling

       QComicBook keeps settings in ~/.qcomicbook directory within these two files:
        - qcomicbookrc - main configuration file
        - bookmarks - bookmarks file

       Both files are plain text files and may be edited manually (with caution!), if needed.

       2. Thumbnails handling

       Thumbnails are stored (if thumbnails disk caching is enabled) in ~/.qcomicbook/cache directory.

       3. Archives handling

       Archived comic books are decompressed to temporary directory  (/tmp/qcomicbook-XXXXX,  with  XXXXX  being
       some  random  number).  This  directory  is  purged when closing current comic book, opening a new one or
       quitting QComicBook.
