When I read a pdf book in my iPod touch using iBook software in landscape mode, I must zoom in each page manually. It means if I proceed to each page, I must zoom in until the left-right margins get aligned with the left-right margins of the display--- approximately 1/2 of a page will be displayed.
My idea is to divide each page in my book into 2 pages of A5. I hope I can do this for all pages automatically because doing it manually for more than 500 pages becomes tedious.
Is there a package to do that?
