This module also exports everything provided by
unstable/gui/pict.
34.5.1 Text Formatting
Adds the attributes for bold, italic, superscript, subscript, or small caps
text, respectively, to
current-main-font while running
text.
34.5.2 Tables
Constructs a table containing the given
rows, all of which must be of
the same length. Applies
t to each string in a
row to
construct a pict. The
hgap,
vgap,
halign, and
valign are used to determine the horizontal and vertical gaps and
alignments as in
table (except that every row and column is uniform).
34.5.3 Multiple Columns
Constructs a two-column pict using
one and
two as the two
columns. Sets
current-para-width appropriately in each column.
Appends each
pict vertically with space between them, similarly to the
slide function.
Combines each pict horizontally, aligned at the top, with space in
between.
Computes the width of one column out of
n that takes up a ratio of
r of the available space (according to
current-para-width).
34.5.4 Staged Slides
Executes the
body terms once for each stage
name. The terms
may include expressions and mutually recursive definitions. Within the body,
each
name is bound to a number from
1 to the number of stages
in order. Furthermore, during execution
stage is bound to the number
of the current stage and
stage-name is bound to a symbol representing
the
name of the current stage. By comparing
stage to the
numeric value of each
name, or
stage-name to quoted symbols of
the form
'name, the user may compute based on the progression of the
stages.
These keywords are bound during the execution of
staged and should not
be used otherwise.
Within a staged slide, the boolean arguments to hide, show,
strike, and shade can be used to determine in which stages to
perform a transformation. The macros pict-if, pict-cond,
pict-case, and pict-match may also be used to create images
which change naturally between stages.
34.5.5 Miscellaneous Slide Utilities
The subsequent bindings were added by Scott Owens.
Adds a blank line of the current font size’s height.
