MComix – GTK+ comic book viewer

MComix is a user-friendly, customizable image viewer.

It’s specifically designed to handle comic books (both Western comics and manga) and supports a variety of container formats (including CBR, CBZ, CB7, CBT, LHA and PDF).

The software is a fork of Comix which ceased development in late 2009. MComix adds bug fixes and stability improvements.

The software is written in the Python programming language and uses GTK+ through the PyGTK bindings. It’s released under an open source license.

Features include:

  • Reads most common image formats, as well as PDF, ZIP, RAR, 7Z, and LHA archives directly.
  • Full screen mode, double-page mode, fit image to window width, height or both.
  • Smart scrolling for easier reading.
  • Manga mode (for right-to-left comic books).
  • Slideshow with configurable delay and steps.
  • Zoom in/out.
  • Magnifying lens with configurable lens size and magnification factor.
  • Bookmark pages and add books to the library.
  • Enhance the image by altering the brightness, contrast, saturation, and/or sharpness. There’s also the option to automatically adjust the contrast of images.
  • Transform images by manually rotating images, auto-rotate images, flip horizontally and vertically.
  • Configurable image quality with bilinear, normal, and hyperbolic scaling modes.
  • Configurable keyboard shortcuts.
  • Internationalization support – translations are available for many languages.
  • Cross-platform support – runs under Linux, BSD, and Windows.
