1. Introduction

   QComicBook is a viewer for PDF files and comic book archives containing jpeg/png/xpm/gif/bmp images, which aims at convenience and simplicity. Features include: automatic unpacking of archive files, full-screen mode, continuous scrolling mode, double-pages viewing, manga mode, thumbnails view, page scaling, mouse or keyboard navigation etc.

2. Requirements

   QComicBook requires Qt libraries version >=5.4.0 (qtcore, qtwidgets, qtprintsupport, qtx11extras, qtprintsupport), poppler-qt5 library and cmake.

You will also need unzip, rar (or unrar), unace, p7zip and tar (with gzip and bzip2 support compiled in) somewhere in your PATH to handle archives. If one of these tools is missing you can still use QComicBook, but you won't be able to open some archives. You may check status of supported archives via Help > System information menu option of QComicBook.

3. Installation

   To compile QComicBook, you will need Qt4 developement packages (usually named -devel- in many distros) and libpoppler-qt4 devel package. Compilation includes three steps:

$ cmake . -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release $ make $ make install (the -D... argument is optional; if not specified, qcomicbook will be installed in /usr/local directory).

If you want to compile qcomicbook with e.g. /usr prefix, but install it to a temporary location for packaging, then pass DESTDIR variable to 'make install', e.g. $ make install DESTDIR=/tmp/package_root

4. Known issues

   • rar/unrar (and unzip/unace probably too) may have problems with files/dirs in the archive, which names contain non-ascii characters (like special characters for you language). As a result they won't be decompressed and qcomicbook may show "No images found" error box.
   • the free (opensource) unrar doesn't currently support 3.0 rar archives. Such archives are reported as empty by QComicBook. It is recommended to use non-free rar/unrar.

5. Bugs

   Ideally, your bug report should include:

   • description of problem.
   • list of steps that reproduce the problem (if it's reproducible).
   • console output from QComicBook (recompile QComicBook with -DCMAKE_BUILD_TYPE=Debug flag to enable debug messages).
   • sample comic book archive that causes problems if problem is only reproducible with particular archive. Please reduce the number of images in the archive to the minimum needed for reproducing bug.
