Oh, I see. In that case, they should use the render-image function
directly. Override the on-paint method, call the get-dc method and
pass that and some suitable coordinates to do the drawing. I recommend
using this only for drawing the final image, don't use other dc
methods (I mean, you can, but

it, they followed the GUI Toolkit intro and arrived at the point where they

Here’s one way, if you mean a bitmap% object:
#lang racket/base
(provide image->bitmap)
(require racket/class
(only-in racket/draw make-bitmap bitmap-dc%)
(only-in 2htdp/image image-width image-height)
(only-in mrlib/image-core render-image))
(define (image->bitmap im
When you say "bitmap" do you mean "bitmap% object"? And if so, why do
they want to do that? If not, do you mean something else?

I just sent $1500 to help sponsor this year's RacketCon. That's an increase
from the $1000 I put in last year, because Vincent St-Amour told me that he and
Matthew Flatt want to scale up this year's event.
I mention this not to bring attention to myself. Rather, I mention it to bring
attention
Is there a public way to change an image created using the 2htdp/image
library into a bitmap?
My students are used to those functions and it would be easier for some of
them to go and build the GUI they want if they didn't have to change over
to explicitly using drawing contexts.
I have looked at

I'll definitely keep that in mind; I'd like to help do that!

Actually, break on any uncaught exception.

Hi, everyone.
So, the background for this e-mail is the following macro:

In short, it allows me to do function definition closely connected with

The problem I ran into last time I worked on this, though, is that I

Thanks, and I'm glad you're having a good time. :)
Currently, the vertex data for frozen shapes is transferred every frame.
The 3D engine is saturating your AGP bus.
I have plans to add either `freeze/send` or a `#:send?` argument to
`freeze`, which will send the vertex data once to reside on
I will second that. The performance difference between the racket dedicated
executable, and running something under a DrR REPL can be surprisingly
huge. It's one of the reasons why I've been slowly transitioning to using
racket-mode under Emacs instead.

Welcome!
Thank you for your past work. Trying to emulate it concretized and
motivated almost all of my high school and undergraduate math classes.
