Programming Racket; How do you overlap a background color with an image. I can get both on my frame but not overlapping. In my code I have

#lang racket/gui

(require racket/draw net/url)

# I created a basic frame

(define frame (new frame% [label "yolo"]))

#Took an image from the internet by

(define image (read-bitmap (get-pure-port (string->url "some image link"))))

# i create my canvas

(define canvas (new canvas% [parent frame]

[paint-callback

(lambda (canvas yo)

(send canvas set-canvas-background "red"))]))

(void (new message% [parent frame] [label image]))

(send frame show #t) Is there a way for me to overlap the two images???
