One of the problems I face with comic readers is that they often stop responding while rendering high quality comic books. Perhaps the solution is to free some memory resources to restore smooth switching between pages of huge comic book. If you come across such issues while reading comics on Mac, you may want to try out Jomics. It’s a lightweight, open source comics reader which supports all those formats in which digital comics are usually distributed, including, CBZ, CBR, and PDF files. While it caches pages of comic books to swiftly navigate between comic book pages, you have option to switch from one-side to two page viewing mode to read comics in book style. Jomics supports numerous image formats as well, which includes, PNG, TIFF, GIF, JFIF and JPEG.
When you launch the application, it will ask you to specify the comic book you wish to view. Select the comic book, enable Open in full screen (if you want to open comics in full-screen mode), and click Open.
The fullscreen mode spans the comic page across the whole screen.
The comic viewer tools are accessible from toolbar. You can magnify the images, export them to PNG, JPG image formats, navigate between pages, and jump to start and end of comics.
Jomics is available for both Windows and Mac. Windows users need JRE (Java Runtime Environment) to run Jomics, whereas Mac users can download Jomics Disk Image (DMG) from product page.
