[worldKit-dev] hi, new member of list

Fri Jan 13 01:55:42 PST 2006

Hi Mikel and list,

I just thought I'd introduce myself on the list rather than lurk, now that I've
joined. I started using worldkit before google earth came out and have decided to
stick with it, rather than become just-another-mashup.

Mikel - your going opensource was a key reason too. Hopefully I find a way to
contribute a bit. My new year's resolution is to release a revamped version of my
site, so I may even get a chance.

> Short story:
>
> You've discovered a bug in how the location of input annotations are calculated.
> I've put in a quick fix, but am going to hold off on releasing it. In the
> meantime, download worldkit.swf from
> http://brainoff.com/worldkit/test/accuplot/worldkit.swf. This is version 2.4
> 20060111-1. Do set , if you are going to display those annotations on the map.
>
> Long story:
>
> Generally, the way worldKit handles zoom is by scaling and repositioning a layer
> containing all the annotations (and another layer containing the images). However,
> Flash internally has a maximum size for any layer. So at a certain magnification,
> the resolution of plotting becomes coarse.
>
> The option is rather than resizing the datalayer, move those annotations every
> time the map is zoomed or panned. This is slightly more computationally expensive,
> so should only be used with necessary. This is set with the unreleased <accuplot>
> option. (Well, really, I should get some solid statistics on this and then decide
> to maybe default to this method anyway).
>
> The reason <accuplot> hasn't been released is the problem you discovered with
> input annotations. The lat/long of the mouse click was determined by the position
> of the mouse relative to the datalayer. When the datalayer is being resized and
> repositioned, this works fine, until of course the maximum resolution is hit. With
> accuplot, the datalayer isn't resized or repositioned, hence the wildly off
> results.
>
> So actually the problem is how the lat/long of a mouse click is calculated. The
> worldkit.swf I pointed at calculates the lat/long without relying on the
> datalayer.
>
> This will go out in the next release. I'd like to release these sort of fixes
> immediately, but I still haven't set a communal code repository yet.
