KPDF

KPDF - View and Print PDF files

KPDF was written for KDE 3 and was one of the earliest Free, Open
Source Applications to successfully view and print PDF files.

Features Highlights

• Thumbnail panel for ease of navigation

• View in Fit-to-screen or Fit-to-width modes, changed with a single click

• Multi-mode searching - the usual facility to search from the Find dialog
   is there of course, but you can also use the filter box above the
   thumbnails to find pages containing that text. Typing '/' then some text
   will start type-ahead searching

• Auto-scrolling - activate by the default keys (Shift+Up and Shift+Down)
   or by shortcut keys to your taste.

• 

  Images with alpha

• 

   With Accessibility colors

• 

   Metalised theme

Development continued for KDE 4, resulting in Okular which adds even more functionality.
