34
36 File
37
38 File menu provies basic operations for loading comic books:
39 - Open directory - open directory containg images.
40 - Open archive - open archived images.
41 - Recently opened - list of ten recently opened archives / directories
42 (most recently opened on the top).
43 - Info - displays information about currenly opened comic book. This
44 includes contents of file_id.diz *.nf o files (if any) as well as mem‐
45 ory usage info.
46 - Settings - allows you to fine-tune some options.
47 - Close - closes currently opened comic book.
48 - Quit - quits QComicBook.
49
50 QComicBook offers some tunable options, available via Settings menu
51 option. These options include:
52 - Background color - the color of the empty area around displayed
53 image.
54 - Hide menubar in fullscreen mode - menubar may be hidded in
55 fullscreen mode if desired; together with toolbar hiding option, it may
56 give you the whole screen for displaying page contents.
57 - Hide statusbar in fullscreen mode - statusbar may be hidden in
58 fullscreen mode, giving you even more space.
59 - Small mouse cursor - toggles small (4x4 pixels) mouse cursor for
60 QComicBook window.
61 - Scaling method - the algorithm used for image scaling; either Smooth
62 or Fast. Smooth scaling provides best quality, but is slower; it is
63 recommened method unless you have really slow machine.
64 - Cache size - the number of pages kept in memory. Value of 0 disables
65 caching; 1 has no effect on performance; 2 or more may improve your
66 experience. Keep in mind, that caching may consume a lot of memory -
67 for example, an 1280x1984 image may take as much as 9Mb of memory!
68 - Preload next page - enables page preloading in the background. This
69 setting takes effect only for cache size of 3 and greater. It is recom‐
70 mended to enable this option, as it may really improve overall experi‐
71 ence.
72 - Use disk cache for thumbnails - thumbnails are saved to disk, which
73 speeds up things when loading them later. Set this option on if you
74 tend to open comic books more then once.
75 - Number of days to keep thumbnails - defines, for how long to keep
76 thumbnails on disk; old thumbnails are deleted when exiting QComicBook.
77 Value of 0 disables purging.
78 - Help browser - allows to choose between simple built-in browser (the
79 default) or any other external web browser.
80 - Forward and backward two pages in two-pages mode.
81 - Open info dialog after opening comic book - when enabled, info dia‐
82 log is opened after opening comic book. You may still open this dialog
83 manually with File/Info menu option.
84 - Confirm exit.
85
86 Note: changing cache size takes effect on new comic book.
87

126 Bookmarks
127
128 Bookmarks menu allows you to bookmark pages in comic books. These book‐
129 marks are however somewhat different than, for example, in any web‐
130 browser and are more similiar to real bookmarks. Each bookmark keeps
131 bookmarked page number (as well as file name), so you can easily start
132 with your comic book from the point, where you last stopped reading.
133

135 - Set bookmark for this comicbook - creates bookmark for current comic
136 book; existing bookmark for this comic book is deleted.

138 current comic book; to remove other bookmarks, use Manage bookmarks
139 option.
140 - Manage bookmarks - opens bookmark manager, where bookmarks can be
141 easily removed.

143 Below these options you can see the list of currently saved bookmarks.

171 Here is some information for people interested in QComicBook internals.
172
173 1. Settings handling
174
175 QComicBook keeps settings in ~/.qcomicbook directory within these two
176 files:
177 - qcomicbookrc - main configuration file
178 - bookmarks - bookmarks file
179
180 Both files are plain text files and may be edited manually (with cau‐
181 tion!), if needed.
182
183 2. Thumbnails handling
184
185 Thumbnails are stored (if thumbnails disk caching is enabled) in
186 ~/.qcomicbook/cache directory.
187
188 3. Archives handling
189
190 Archived comic books are decompressed to temporary directory
191 (/tmp/qcomicbook-XXXXX, with XXXXX being some random number). This
192 directory is purged when closing current comic book, opening a new one
193 or quitting QComicBook.
