3.5 Configuration

Parameter that determines the font size used by t, para, etc. The default size is 32.

Parameter that determines the font size used by t, para, etc. The default is platform-specific; possible initial values include 'swiss, "Verdana", and "Gill Sans".

Parameter that controls the amount of space used between lines by para, item, and subitem.

Parameter that controls the width of a pict created by para, item, and subitem.

Parameter used by the default current-titlet to colorize the title. The default is "black".

Parameter whose value is a function for assembling slide content into a single pict; the assembling function takes a string for the title (or #f), a separation for the title (if any) and pict, and a pict for the slide content (not counting the title).

The result is of the assembler is ct-superimposed with the client area, but the result pict might draw outside the client region to paint the screen margins, too.

The default assembler uses titlet to turn a title string (if any) to a pict. See also current-titlet and set-title-h!.

The slide assembler is not responsible for adding page numbers to the slide; that job belongs to the viewer. See also current-page-number-font, current-page-number-color, and set-page-numbers-visible!.

(current-titlet)  (string? . -> . pict?)
(current-titlet proc)  void?
  proc : (string? . -> . pict?)
Parameter to configure titlet. The default is

(lambda (s)
  (colorize (text s (current-main-font) 40)

If this parameter is changed such that the result is a different height, then set-title-h! should be called to update the value produced by title-h, titleless-page, etc.

(set-margin! amt)  void?
  amt : real?
Changes the margin that surrounds the client area. See also margin.

(set-title-h! amt)  void?
  amt : real?
Changes the expected height of a title, which adjusts title-h, client-h, full-page, and titleless-page.

(make-slide-inset left-inset    
  bottom-inset)  slide-inset?
  left-inset : exact-nonnegative-integer?
  top-inset : exact-nonnegative-integer?
  right-inset : exact-nonnegative-integer?
  bottom-inset : exact-nonnegative-integer?
Creates a slide inset, which describes a number of pixels to inset the viewer for a slide on each side.

(slide-inset? v)  boolean?
  v : any/c
Returns #t if v is a slide inset created by make-slide-inset, #f otherwise.
