Create maps from an SVG file in Roassal

Hi there,

I'm trying to import an SVG file describing the provinces of Belgium in Roassal.

I've cleaned an SVG file found on wikipedia and trying to import it.

I'm trying to imitate the way it is done with Countries. So:

RTMapBuilder class>>provincesOfBelgium
^ #(#antwerp #brussels #eastFlanders #flemishBrabant #hainaut #liege #limburg #luxembourg #namur #walloonBrabant #westFlanders)

and implemented to corresponding SVG paths. Here's one example:

RTSVGPath class>> antwerp
^'m 177.419,25.0693 1.379,-3.5593 -2.986,-1.3778 -3.33,0.5742 -0.114,-3.1001 -4.019,-4.0187 1.492,-5.9704 -2.181,-2.8706 -1.952,-0.2298 -1.034,-1.2628 -2.411,5.1667 -3.673,3.7892 -3.101,-2.067 -5.396,1.378 -2.068,-1.8371 4.479,-0.9188 0.345,-5.1667 -6.2,-2.1815 -4.938,5.741 0.114,2.8704 -8.611,-0.574 1.264,-5.5112 -5.397,0 -6.43,3.4444 1.263,4.5929 2.411,2.7555 -1.492,2.6409 -4.478,-0.6891 0.115,-2.7555 -6.43,0.3443 0,2.4112 2.296,0.5743 -0.345,5.5112 3.904,1.0336 -3.1,3.3295 3.056,7.4863 0.504,5.9475 -7.923,0.2296 -2.985,3.1002 1.722,1.837 -0.114,3.5595 2.889,0.4893 3.352,-0.9423 7.038,4.5375 3.704,-0.5553 1.759,1.7593 3.149,-1.7593 4.075,2.1297 2.963,-3.6118 11.112,-1.7592 0.092,3.3337 11.576,-3.6113 1.204,-3.0562 5.001,-0.8332 2.129,-3.8894 4.723,-0.7409 0.741,-1.9448 2.223,0.8336 1.481,-0.8336 0.186,-4.9079 -4.075,-2.0373 1.605,-5.4063 z'.

Very naively, I've tried:

provinceExample
    "self new provinceExample"
    | b |
    b := RTMapBuilder new.
    b countries: RTMapBuilder provincesOfBelgium.
    b color: Color lightGrey.
    b open.

Which does not display anything.

I suspect the problem lies in the coordinates of my paths. Is there a README somehwere or the original file that was used to generate the world map of the examples?

Cheers,

Francois

Apparently the path parser doesn't conform to specs?

in the code I see a nice comment "The description of SVG path, says that M and m may accept more than one coordinates. In practices, this is rarely the case. "

This also applies for other commands that should support multiple coordinates.

anyway, try this (I made all line-to commands explicit):

It works with the explicit line-to:

Any hint on how to force its inclusion in Inkscape ?

Yep, you're right the path parser doesnt not conform with the spec. From Section 8.3.2 of http://www.w3.org/TR/SVG/paths.html#PathDataMovetoCommands

If a moveto is followed by multiple pairs of coordinates, the subsequent pairs are treated as implicit lineto commands.

Thanks for the pointer :)

If you have any idea on how to output those explicit "l", I'm all ears...

You're right Baarle-Hertog neighbourhood are not in the SVG file :(

It should'nt be a problem to express their position in SVG. Have a look at the Comines-Warneton 'which is part of Hainaut) stuck between France and West-Flanders ;)

Re: Create maps from an SVG file in Roassal

Hey, what happened to Voeren? https://en.wikipedia.org/wiki/Voeren That’s part of Limburg which is also not on the map. That’s already 2 parts of Flanders left out. This is grounds for an ‘affaire communautaire’ to happen soon! :-P

Re: Create maps from an SVG file in Roassal

Flanders geography looks way too complicated for a sane brain :p

Re: Create maps from an SVG file in Roassal

Hi François,

I don't think it's worth fixing in the current implementation,

however there is already available SVG importer into Pharo, so I'll try to find a way how to adapt it. It should support regular SVG (circle, rectangle, ...), not just path.

Re: Create maps from an SVG file in Roassal

This is Athens-SVG btw (not loaded by default in Pharo, but available in Athens repository).

I think Stef mentioned it several times in regards to RTSVGPath.

Re: Create maps from an SVG file in Roassal

Okidoki !

I've found the option to explicitly include the "lineto" in Inkscape (see the attached screenshot of the Preferences).

thanks!

Especially if you want to exclude the parts of Baarle-Nassau inside
of Baarle-Hertog

Re: Create maps from an SVG file in Roassal

Hmm, maybe Athens-SVG will not be so simple, because it's paint-only so I would still have to write a lot of stuff around.

But maybe we could grab the SVG path lexer that's there (and is better than in Roassal) and use it to simplify and improve current implementation, so even multi-coordinate commands work.

I shall investigate more...

Re: Create maps from an SVG file in Roassal

Yes, it would be great!
I first tried to understand the SVG parser in Athens, but I could not make it to work. So I wrote the one in Roassal. But indeed, we need a better thing.

By the way, there is no parser supported by Cairo? I’ve just found this: http://cairosvg.org/project_description/

Cheers,
Alexandre

Uh?
Of course it is working. You can import SVG file.

Usually this approach does not work because two half done is not equal
to one
