Oh, btw, I have been following your blog for a while. Great work with your SVG Challenge. Just in case you’re interested, I think the font Scott used on its chart is Trebuchet MS bold.

The lack of subpixel positioning in firefox will make the rendering worse than the photoshop’s one, but you will get closer than with your current font.

One could argue that you can call the above javascript if the user number is different from 0, but that will break somewhat backwards compatibility and complicate even more the startup of the home page. Currently it has to decide what coordinates to take: those passed in “get” like params for backwards compatibility with old links, those passed in the hash (for new links), those stored in the cookies, or a mix of these three? I was not feeling like adding another layer of possible coordinates.

On the backwards compatibily problem, right now a link to www.panoramio.com/#user=x directs the user to a map in the position and the zoom that he was using last time he visited Panoramio, showing only x’s photos. Not to the center of x’s photos. It’s not a big deal, but together with the previous point, it convinced me that it was best to just put the coordinates directly in the link.

var center = new GPoint( (maxLng + minLng)/2, (maxLat+minLat)/2 );
var delta = new GSize(maxLng - minLng, maxLat - minLat);
var minZoom = map.spec.getLowestZoomLevel(center, delta, map.viewSize);
map.centerAndZoom(center, minZoom);

or map.getBoundsZoomLevel in forthcoming API version 2.31.

The methods I found on the google maps discussion group were “start proving zooms untils you find one in which all the markers fit” (in javascript).

That’s extremelly inefficient. If you know the size in pixels of your map you can do much better.

I derived the equation:

$zoom = ceil(25 + max(log($lt_delta / $map_height / 180, 2), log($ln_delta / $map_width / 360, 2)));

to find the zoom in function of the latitude / longitude delta you want to enclose.

I’m putting it here in case it helps somebody.

Cheers,

To add insult to injury, I even remember an old bug in mozilla about using alt text for tooltips if there was no title (afair it degenerated on a big flamefest).

I’ll patch it with the next row of fixes.

Thank you Johan!

I have title=”Remove from favourites” on highlighted stars and title=”Add to favourites” on non highlighted stars.

Am I missing a title somewhere?

As for the zoomToBounds, sure, I thought about it some days ago, but someway it got out of my head. I will put it in the “in a map” link asap (I have some unstable changes committed to my repository, and I want to stabilize these before).

Thank you for your comments Johan!

Cheers,
