Hi Jody,
/>> - Draw the image as geotools is drawing into it... this is what uDig
does.
/Can you please supply me with a code sample regarding how uDig does
that? We really need this feature, our customers dislike the time lag
(datasets are large).
Thanks,
Sergey

Yes; a couple of ways.

- Get a volatile image and use that to draw into. It is tricky Java 2D
programming (because you need to redraw if windows are moved in front of your
image) but it is effective.

As far as I know, default geotools drawing mode is to draw on offline
buffer and then render this buffer to the screen. On the opposing side,
OpenJump (for example) draws everythink it can draw immediately.
This give user the feeling of more responsive interface, because hey -
something is going on my screen. So if one will draw streets dataset
he/she will notice how streets are being rendered one by one.
Is it possible to do something similar for the geotools, I mean to draw
every feature obtained for drawing immediately to user, not to offscreen
buffer?
Thanks in advance!
