Description:
simple PDF viewer with two layouts
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.
