At first glance, it is really powerful “Wonderfulshare PDF Editor Pro” – is misleading.
All it can do “PDF-XChange Viewer” (free-version). Even more. The following functions are “PDF-XChange Viewer”
1. OCR (almost any language in the world)
2. I have a “PDF-XChange Viewer” – portable
3. It is possible to put a password (it is a pity that i can not paste screen shots, and write a lot)
4. Rotate any page for readability and after saving – will remain rotated page (water marks will NOT!)
5. You can add:
a) Stamps, Note, typewriter, text, note, highlighting, strikethrough, underline, arrow (you can change the type of arrows), lines, various figures, pencil and eraser for pencil.
b) Change the color of the lines (figures, footnotes and text areas)
6. Measure the length of the perimeter of the area (only configurable I do not remember as)
7. It works from the “WindowsXP” and above
