Figure 11: Slide property elements/tags.
infotag a piece of information to be associated with the slide; this is ignored during the experiment
and is merely output with the results
name a descriptive name for the slide; used in results output
seqno the sequence number of the slide
focus name of the component to focus
mouse advance an empty tag indicating that the mouse is to be monitored
advancekeys characters that can be used to advance the slide
rows a comma-separated list of proportional row heights in decimal format, summing to 1.0
cols a comma-separated list of proportional column widths in decimal format, summing to
1.0
font tags face, size, style defining the properties of the font
fgcolor tags r, g, b defining red, green and blue components of the foreground colour; or a name
defined in java.awt.Color
bgcolor as above, defining the background colour
Sub-element tags for complex properties like font and colour
r red component of a colour (0-255)
g green component of a colour (0-255)
b blue component of a colour (0-255)
face name of the font
size integer point size for the font
style a number representing the font style (0=normal, 1=bold, 2=italic, 3=both)
The logical font names are mapped to local system fonts on the computer running the applet and thus may
still give a varying visual appearance. Despite this, the variation should be minimal if you are working within
a particular social group — for example if you are running an experiment in Japanese, your subjects may be
expected to have the necessary underlying fonts.
You should be aware of these potential variations, particularly if your experiment is potentially sensitive to
variations in the visual environment. The only way to be sure of what your subject sees is to use an image.
Colours Precise colours can be specified by defining values between 0-255 for the sub-properties r, g, b of the
(background colour) and (foreground colour) tags. Alternatively, some simple colours
can be specified by name instead of rgb tags (see figure 12).
