I basically agree with Alex, as the internal structures of pict don't
really keep information in that way, but a "best effort" might be to
draw it into a bitmap and then use the bitmap to find the average
color or the most common color (perhaps with some error bounds on what
colors count as "the sa
I don't think such a procedure can be written. at least not for the general
case.
First, the color of `(filled-rectangle 30 30)` is not black, but whatever
color was installed in the drawing context when the filled rectangle was
rendered. You can change it to red using:
(colorize (filled-rec
Okay, so "edit the file" is the answer. That works for me. Thanks!

You can parameterize `current-command-line-arguments` like so:
```
#lang racket
(require racket/cmdline)
(define foo (make-parameter 7))
(parameterize ([current-command-line-arguments #("--thing" "9")])
(command-line
#:program "foo"

Is there a way to specify command line arguments when running inside
DrRacket?
For example:
#lang racket
(define foo (make-parameter 7))
(command-line
#:program "foo"
#:once-each
[("--thing") thing "The thing" (foo thing)]
)
(displayln (foo))
If running in DrRacket, how can I make this spit
Hi,
Using the 'pict' library, I could not find predicates regarding color in
the doc.
Is there something like
(get-color (filled-rectangle 30 30)) --> "black"
somewhere?
If not, how can I make a reliable color predicate?
Thanks,
Raoul
