NAME

       katarakt - a simple PDF viewer with two layouts

SYNOPSIS

       katarakt [OPTIONS] FILE|URL

DESCRIPTION

       It’s a PDF viewer. It views PDFs.

       There are currently two layouts. The presentation layout is very simple and only supports
       scrolling on a per page basis. As the name suggests the current page is displayed in the
       center and zoomed to fit the window. It is active by default.

       The grid layout is much more advanced and offers continuous (smooth, per pixel) scrolling,
       zooming and adjusting the column count. Pages keep their correct relative size and are
       shown in a grid.

OPTIONS

       -p, --page NUM
           Start showing page NUM.

       -f, --fullscreen
           Start in fullscreen mode.

       -h, --help
           Print help and exit.
