3.7. thumbpdf

The thumbpdf package by Heiko Oberdiek installs the Perl program thumbpdf on your system. With the help of thumbpdf and Ghostscript (which should also be installed), you can create thumbnails for the PDF document (to be seen when you click on the “thumbnails” register card in Acrobat® Reader[1]). Thumbnails are embedded images of the document's pages, drawn in small size and resolution. Their purpose is to facilitate navigation through the document (of course only if the PDF viewer supports them).

Thumbnails will be created automatically by the lyxtox script and will be embedded in the PDF document whithout any user intervention (see Section 7.1.4.7 for a detailed description). You just have to take care that the thumbpdf package is installed.

You can download thumbpdf from CTAN: thumbpdf. After download and extraction of the package, the files

• readme.txt (documentation)

• thumbpdf.tex (pdftex)

• thumbpdf.sty (pdf(e)tex, pdf(e)latex, (e)tex, (e)latex)

should be moved to

• texmf/doc/generic/thumbpdf/readme.txt

• texmf/tex/generic/thumbpdf/thumbpdf.tex

• texmf/tex/generic/thumbpdf/thumbpdf.sty

respectively. The Perl script itself, thumbpdf.pl, may be renamed to thumbpdf:

mv thumbpdf.pl thumbpdf

Ensure that the execute permission is set:

chmod +x thumbpdf

then move the file to a directory where the shell can find it (according to the PATH environment variable, e.g. /usr/local/bin/):

mv thumbpdf /usr/local/bin/thumbpdf

Requires:

• Perl5 (version 5 of the perl interpreter).

• Ghostscript:

  • Thumbnail generation: version 5.50 or better 6.0.

  • Thumbnail inclusion with ps2pdf: version 6.0.

• pdfTeX.
