Ticket #2376 (closed bug: fixed)
mouse wheeling results in fractional zoom levels
|Reported by:||tschaub||Owned by:|
Since r9799, you can unintentionally get fractional zoom levels using the mouse wheel. The easiest way to see this problem is to add a console.log(deltaZ) line to the wheelChange method in the Navigation control (line 213). Alternately, open up an example and use the mouse wheel to zoom just a little bit. Try map.zoom in the console to see numbers like 1.6666666.
The wheelChange method expects an integer deltaZ. The onWheelEvent method in the MousWheel handler does e.detail / 3. I don't see anything that says what to expect for values in the docs, but I see integer values for detail in FF3.x.
