Yeah, I... really have no idea what's going on with this bug. Nowhere in
my code, or any of lizorkin's ssax code or the sxml-tools module is any
reference made to any identifier even resembling the word 'stxloc'.

OK. Here is what I am trying to do.

I am trying to rotate the guy's arm by the dynamic degree denoted on the
bottom-left corner of the screen. I just have to center the rotated image.
How would I go about doing that?

Here's a simple example that illustrates one initially surprising behavior
with rotate. This wiggling really confounded me the first time I saw it.

Here's an example I have that shows what Stephen suggested. It's overly
complicated with the trig, but the rotation is a small object overlaid on a
larger circle.
Specifically, the blue circle background is rotating back-and-forth and the
small red circle is along for the ride. But it looks like

I've noticed this bug too, but I think that, in the meantime, you can
just do an "in place" build. That is, create some build directory to
run configure in, but don't pass an install dir and instead let the
make install phase go directly into the plt tree where you're building

I gave my students a bunch of images created with 2htdp/image to try
to recreate.
All of the images involving bitmaps appear as black circles on Windows.
Even if you create the image in the interactions window and then copy
it into the definitions, the same big, nasty black circle appears.

But these are two orthogonal questions:
-- rotating an image
-- placing an image in a "constrained" background
Shouldn't they be provided by two distinct functions?

Well, the 2htdp/image library does not work like that. If you overlay
and the rotate then your background will be roated. If you rotate and
then overlay the you may place things in different (relative)
positions but you still don't get any different behavior by rotating
around different points.

Perhaps Matthew is concerned not so much with the
resulting orientation of the image

An ".ss" to ".rkt" conversion was missing. I've pushed a fix to the git

The mistakenly committed debugging `printf' was at least useful in this

In a sense, it's the center (more precisely, the center of the b
There is no difference between rotating an image around different

Hi guys,
Hope you all having a great day.
I got a question for you all.
I am trying to rotate an image around a certain point. Using the 2htdp/image
and its rotate function, it seems to be rotating the image.
But what is it rotating around?
I appreciate all your help.
Thank you.
