Hi!
I tested the new mouse wheel zoom with the nightly build from 23-Feb-2010
02:12.
(A) In previous versions the zoom function zoomed-in to the current position
of the mouse cursor. The new behavour is, that it just zooms to the position
in middle of the layerviewpanel. I'd like to have the old behaviour when
zooming in.
(B) Also there are some problems when zooming in and out having layers with
approx. 5000 features. I think the zooming algorithm (1) uses an image from
the current view of the layerviewpanel and zoom that image and (2) then
rerenders all the features to replace the image. When I zoom with the mouse
wheel the view jumps between (1) and (2), e.g. it finishes rerendering the
image (2) of an previous zoom level when (1) already happened.
Greetings
