Title : Slides Viewer for an LCD Projection Panel
Originator : Dr S. W. Moore
Special Resources : none


The laboratory now has an LCD projection panel for electronic display of slides. It offers a resolution of 640x480 with medium contrast and a small range of colours. This can be neatly combined with a portable computer for the roving lecturer.

To make best use of the LCD display a careful choice of neatly rendered fonts is required. Colour also needs to be wisely chosen, particularly since many portables only offer a 4~bit deep display.

Slides could be generated in LaTeX and displayed with ghostview. Unfortunately ghostview makes a poor job of rendering postscript fonts when only a limited number of pixels are available. Alternatively, slides could be prepared in HTML and displayed with netscape. Alas netscape only works with mono or 8~bits per pixel displays. Furthermore, a complex distributed hypertext environment is not required. None the less, HTML has the attraction that material could easily be supplied via the web for later perusal.
