   EBookDroid is the best viewer for scanned PDF. However it lake some features that availble in other application, namely "Perfact Viewer Donate". I mean: Smooth filters: Averaging, Bilinear, Bicubic, Lanczos3

   These filters of usefullness when viewing a scanned PDF book prepared by scanner USING LOWER THAN 300 dpi like 75 dpi. I have many books in PDF formates the persons who scanned them have no enough experince in using scanner for creation PDF books. They take PCX or JPEJ using 75 dpi which make character less clear esspecially when zooming like "autocrope". Using these filters in Perfact viewer make this issue less sever ......... So, it is very nice to add such filters to EBookDroid. But you have - if you add them to insuer that no lag in application will happen when using these filters.

   We do not like clon for Perfact viewer. But we wish some thing much better than Perfact Viewer
