Its always a pleasure to read a flip book there was a time when all the books use to come in .pdf format and it wasn't that fun to read them but now the books are more interactive then ever before. Specially the comic books like this. It have only been possible due to the use of Flip book software . By using these software we can in fact convert a pdf file into flip book by our self and hence its very to be used. Reading in a flip book format is much better experience then reading in a regular pdf format.
