r.ps2web

A script that generates an HTML presentation from a Postscript file. Every page of the document is converted to a JPEG image, and simple links provide the transition from slide to slide. Useful to generate web versions of PowerPoint presentations.

Usage

r.ps2web

-title "presentation title" Title of the presentation. Watch for the double quotes when the title has more than one word.

-psfile postscript_file Postscript or PDF file. Can also be a .prn file (when generated by Windows)

-screen screensize Window size of the target presentation. By default 800x600, can be set to any value.

-l Landscape mode. To use when slides are generated in landscape format. Almost compulsory when converting PowerPoint presentations.

-r resolution Resolution used by Ghostscript to generate the images. 200 dpi (dots per inch) by default. Can be set to 300 dpi for high resolution, or to 100 to make a quick test.

Sample invocation

Postscript file : file.ps

r.ps2web -title "My Presentation" -psfile file.ps -l

The script generates a directory named "web-file", in which the entry file index.html contains the thumbnails of the slides. To start the presentation, click on the first slide.

Sample presentation : ezscint

This script is a combination of 3 freeware tools commonly found on the Web:

gs (ghostscript), to render the postscript pages into high-resolution images

ImageMagick, to crop and reduce the size of the high-resolution images

imgidx.pl, a Perl script that generates HTML navigation code from a series of images.

Availability

Preferably Linux workstations. Also runs on SGI (see note below).
Needs the above utilities to be installed. The first two are standard on most Linux distributions. The last one has two be downloaded and installed separately and needs Perl 5.
Highly demanding in terms of memory and computation time.
Runs on pollux, although the use of this script on pollux would be considered as corporate sabotage of computer resources.

Limitations

Ghostscript has to be able to convert the document if the conversion is to be successful.
