Notes on text wrapping/layout for anyone interested...
There are a lot of approaches just for wrapping lines of text (even
before you get into interacting with other aspects of page layout).
The simplest is to assume a fixed-pitch font and a known max character
width per line, and just scan t
Yes, but you must implement it yourself.
This simplest one works for fixed-width font (implemented with pict-lib,
you get the idea):
(define desc
(lambda [txt size width #:head [head (blank 0 0)] #:style [fstyle null]]
(define {desc0 txt size width fstyle}

This is a function that you'd have to implement yourself. You could break
the string up on spaces and then put them beside or above each other, as
appropriate. (A real word processing program uses a more complex algorithm
that involves adjusting the spaces between words (and possibly elsewhere, I

When using 2htdp/image to create a text image, is this possible to specify a
"bounding box" for the image, so that the text could be wrapped to fit that box?
E.g., below line:
