404, but I'm going to assume you mean

Yeah that's it. (It got 404 because I got the link before it had synced)

Also, I think some of those drawn maps should be included in the game as examples, such as Globe.

Added. Actually, this one was more complex because the points needed cleaning up to simulate occlusion. Oh well. Looks ok I think.

hum, do i understand everything ?

it would turn a basic svg in a map, but not a map as we dl from unit22 but a map in wich different theme texture can be applied, with girder and land object ?

(if i didn't understand that just mean my english is bad, not mean that you didn't explain good )

a basic one, just to see what you mean

It makes a drawn map - you know, if you select drawing a map in the map filter, click the preview and start scribbling away, you can choose to save. The format is saves in has an extension of .hwmap

You can choose to load them as well. I'm surprised there aren't more people sharing their drawn maps on the website. Maybe they are waiting for the eraser and variable brush unc0rr added in next version.
Drawing straight lines exists in 0.9.17 and 0.9.16 - click down with the mouse, press ctrl, then move the mouse, and you get a nice straight line - you could use this to very easily replicate the map that you posted in the SVG with only 18 lines, although if done in 0.9.17 you might need a few more to increase the thickness due to lack of variable brush support.

And, yes. It is decorated by the theme, so including girders and objects unless you disable those in the scheme preferences.

Two questions: is there a size limit for this? Also, did you guys add a fill option in 9.18 too?

There's no fill option, but most uses of fill can be handled fairly efficiently by just using the mousewheel to pick the max brush size.
For example, if you pick max brush size and use ctrl-click to draw accurate horizontal lines, you can fill the entire map using only 4 horizontal lines.

You can then use the eraser to draw a cave.

As for size, that's covered in the wiki page. Since these are SVG, you can scale them to whatever dimensions you want, but drawn map only draws to the current hedgewars land limit - that means 4096 wide and 2048 high.

If you convert an SVG and specify coordinates outside of this, they just won't get drawn and will get clipped off. You can do that, but it'd be more efficient to "crop" the SVG first if you want that effect - that would save on nodes being loaded by hedgewars.
