Re: [racket-users] put-image

[Shu-Hung You]

One option is using save-image from 2htdp/image to save the images as
PNG files and open them using external programs.
https://docs.racket-lang.org/teachpack/2htdpimage.html#%28def._%28%28lib._2htdp%2Fimage..rkt%29._save-image%29%29

If you can use a different language (say racket), another option is
using show-pict from pict:

;; needs the 'require' form from racket (or racket/base)
(require racket/gui/base (only-in pict show-pict))
(show-pict
 (put-image
  (circle 50 "solid" "green")
  50
  50
  (square 100 "solid" "blue")))

Since many functions in pict have the same names as those provided by
2htdp/image, you need only-in to require only the show-pict function.

Re: [racket-users] put-image

[patric...@gmail.com]

I was able to use the Bootstrap teachpack. I am running my program from the 
command line and racket returns *#*. Is there a way to view the 
output outside of Dr. Racket?

Re: [racket-users] put-image

[Robby Findler]

Okay, I've added it. It is pretty straightforward to define it in your own
code in the meantime, Patrick:

(define (put-image i1 x y i2)
  (place-image i1 x (- (image-height i2) y) i2))

Re: [racket-users] put-image

[Sorawee Porncharoenwase]

As explained in documentation of WeScheme
,
put-image is only available in WeScheme. Racket and its libraries don’t
have this function.

It’s easy to implement it yourself, however, by using place-image and
image-height. Both are available in 2htdp/image
