IMPRESSIVE-GETTRANSITIONS(1)				      Debian GNU/Linux manual				      IMPRESSIVE-GETTRANSITIONS(1)

NAME

       impressive-gettransitions - Generate Impressive info scripts for LaTeX presentations

SYNOPSIS

       impressive-gettransitions FILE.tex

DESCRIPTION

       A simple script to produce a .info file for use with Impressive, using special comments in a LaTeX/Beamer file. FILE.tex is a file to be
       parsed into .info file. For each /fullpath/blah.tex /fullpath/blah.pdf.info gets produced.

SYNTAX

       In the LaTeX document, impressive-gettransitions counts the pages to determine the PDF slide number of each one.

       The simpler page changes are automatically detected, that is:
	   egin{frame} and:
	   pause

       Other, more elaborated page changes must be noted with a %O comment:
	   item<1-> Foo
	   item<2-> Bar %O

       The transition to apply can be specified in a %O comment:
	   egin{frame} %O SlideUp

OPERATION

       When the .info file corresponding to the LaTeX document already exist, impressive-gettransitions does not clear it, but only adds the
       transitions if finds to it.

       Thus, if you modified your document in a way that requires to completely replace the transitions, manually clear the PageProps section of
       the .info file. This can be done by running the following sed command:
	   sed -i -e "/^PageProps = {/,/^}/d" FILE.info
