PPower4 is a post processor for LaTeX files to build pages step by step.
PPower4 provides a small
LaTeX package (
pause.sty) which let's
the user insert small coloured spots (using the command
\pause) in the PDF file where a break
should be make during display. During postprocessing PPower4 removes these coloured chunks
and adjusts the page number. This leads to the impression that the
same page is displayed step by step.
Additional packages are provided for setting background colours
background.sty) and page transitions
pagetrans.tex) - this actually is a
hyperref.sty and can be
used with any LaTeX based solution.
