DESCRIPTION

       QComicBook  is  a viewer for comic book archives containing jpeg/png/xpm/gif images, which
       aims at convenience and simplicity.

       Features include:
        - automatic decompression of zip (cbz),  rar  (cbr),  ace  (cba),  targzipped  (cbg)  and
       tarbzip2ped (cbb) archives
        - full-screen mode
        - two-pages viewing
        - page scaling
        - mouse or keyboard navigation
        - bookmarks
        - 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

MENU

       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

       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.
