OK, I found a dataset that easily reproduces what I think is Benjamin's
mouse wheel zoom redraw anomaly. What seems to be happening is that in
areas where vector redraw takes a few seconds or more, multiple mouse wheel
zooms, separated by more that .7 seconds, do not allow the screen to repaint

Hi Benjamin,
Could you try to reproduce the anomaly when mouse wheel zooming with the

Maybe you can use the drawing algorithm that draw the geometries like a
pencil sketch when zooming with the slidebar (and then rerender the
geometries at a given time interval).

Hi Larry,
there should really be an option the choose between the old and new zooming
algorithm (if possible).
Zooming out feels slowly, when I first have to wait for the rendering of

level.

Hi Benjamin,
(A) I like the old zoom to mouse position behavior too. I just haven't
gotten the zoom to cursor math right yet.
(B) You might be right. I've noticed an occasional anomaly too, but can't

It should now zoom in when the wheel is rolled away from your hand as other
mapping programs do.

Hi,
Excellent job. Mouse wheel zooming gives a good feeling because screen
is updating fast and from the server side I can see also that no
unnecessary WMS calls are sent. That gives more speed for OJ user

More Mouse Wheel Zooming updates. I fixed some problems with mouse wheel
zoom in and zoom out in the same half second causing radical changes. The
Timer period now resets while the wheel is still moving, and I changed the
Timer period to .7 seconds to better reflect actual use.

OK, I have committed an experimental version of AbstractZoomTool that
incorporates a deferred mouse wheel zoom for half a second. It does an
image stretch from the center of the panel until the half second expires.
Please test after tomorrow's nightly build.

Hi Jukka,
The behavior you described is what I programmed for the mouse wheel

wheel. It is just a matter of finding time to do it. As you can imagine,
this is fairly difficult code to write, but I believe it to be an i

Nothing profound, just that in general, it isn't really a good idea

Before you commit, can you replace duplicate method calls such as

once. There are two reasons for this.

Some of the functionality you are talking about is already present

Normally I hate people messing with my mouse pointer but in this case I

Here are the three options for mouse wheel zooming that I see.

OK the code to perform the mouse wheel zoom at cursor is:

Now that I think of it, I guess I didn't really give the mode a
chance. The ZoomAt method will zoom to any point, but then that point
becomes the center of the window. In order for it to work correctly,
you would have to make a ZoomTo? function that would keep the zoom
point under the cursor.

At the moment when you zoom it zooms in and out based on the existing

What would be useful is if you could use the mouse location as the
center when zooming in (and maybe out).
