Roboreader is a versatile file viewer with a minimalist interface, supporting a vast array of file formats. Unlike common image and comic viewers, it hides many of the interface options and displays the file with a cleaner look. You can access advanced bookmarking, image rotation, copy/paste and other options via right-click context menu. While it supports a large array of files, including CBZ, CBR(Comic formats), RAR, ZIP, 7z (Compressed file type), animated GIF, JPG, JPEG, JPE, JFIF, BMP, PNG, TIFF, TIF, ICO files, as well as JPEG image file, you can open comic files in two panned windows which makes reading comics a lot easier.
You can use the context menu to switch between multiple comic pages and open CBZ or CBR comic files side by side for easy viewing.
The context menu provides options to bookmark the opened image, run slideshow of currently opened images/comic files, rotate images clockwise, counter-clockwise, and so on.
You can use the square-imaged button present at top-right corner to switch between fullscreen and default view.
The Settings menu contains many advanced options including image resizing, zooming, fant, bilinear, bicubic hybrid, etc.
Under Misc tab, you’ve options for viewing layered windows, auto centering, top centering, sorting, archive browsing and much more. From Slideshow tab, you can schedule time lapse for slideshows.
So if you are looking for a minimalist image and comic viewer, then Roboreader might just be what you are looking for. It works on Windows XP, Windows Vista and Windows 7.
