****************************************************


Hello everbody;

I was looking for a PDF viewer for a long time. I tried "http://viewerjs.org/", but I didn't get the result I wanted exactly. or I failed.
After I discovered PDF.js.
Finally I made a B4Xlib for PDF viewer. jPDFviewer library is based on github project.
I know... The method I use can be a little foolish. But its works.

HAVE A FUN...
