Dear Racket users,
I'm working on some Scribble documents that use both the @examples command and
the 2htdp/image library. Here's a short example.
--- START OF EXAMPLE ---
#lang scribble/base
@(require scribble/example
teachpack/2htdp/scribblings/img-eval)
@examples[#:eval (make-img-eval)
(circle 10 'solid "blue")
(circle 15 'outline "red")
(beside (circle 10 'outline "black")
(circle 10 'outline "black"))
]
---- END OF EXAMPLE ----
The examples work fine when generating both HTML and PDF. However, in the HTML
rendering, the alt text for the images is always "image", which is not
particularly accessible. I've made a commitment to making sure that my Web
pages are accessible. So I'd like to include alt text. For example,
"A solid blue circle of radius 10"
"A hollow circle of radius 15 outlined in red"
"A hollow circle of radius 10 beside a hollow circle of radius 10"
I know that WeScheme.org generates such alt text (well, Aria text, but it's
similar enough). Does that facility exist in Scribble?
Thanks very much!
