In the latest development version:
The `slideshow/pict' library no longer depends on `racket/gui' --- just
`racket/draw', which can be used without a GUI display (e.g., an X
connection).
Scribble now renders picts directly for HTML or PDF output. The
document source
#lang scribble/base
@(require slideshow/face)
@title{Faces}
@section{Happy}
@(face 'happy "yellow")
@section{Not So Happy}
@(face 'unhappy "lightblue")
produces what you'd expect.
More precisely, Scribble renders values that are convertible to PNG
(and optionally PDF format) via the new `file/convertible' protocol.
The protocol is simple, but the indirection keeps Scribble from
depending directly on the pict library or vice versa. Plain `bitmap%'s
are convertible to PNG, too, so a bitmap in a Scribble document renders
as its image.
As an example, the "Quick" document now mostly uses the plain
`interaction' form with an evaluator that has `slideshow/pict' loaded.
In the Slideshow docs, some ASCII art in the description of the pict
datatype has been replaced by a real picture (that is implemented as a
pict, of course).
