python - Array of coordinates to SVG Polygon shape -

-

I am making a random map generator in Python I am creating random political states. I have an algorithm that creates a list of X, coordinates for the list of areas Y. These areas need not be narrowed, so the list of digits can produce many polygon shapes.

Currently, I am converting the list of points into path strings, essentially a very long line that wraps around to create a shape, not exactly what the path was intended for. It is very disabled; If you have a particularly long time zone then it can be several thousand characters long. Also, using this method, the stroke property essentially functions as an asset filled, which means that I can not drag the boundary line between the fields.

The real question:
How can I change the list of digits to one or more polygons? More specifically, I need a polygon "line" string.

Obviously creating a algorithm in your area is a bitmap. You need to find out the size of the frame instead of making the shape outline "run-length encoding" instead of finding the outline of the shape.

Describing how to do this is a little beyond SO. answer. In general, this is called "bitmap tracing". This is a popular library for utensils . I think there are dragon binding for it.

Otherwise, you might work better by taking advantage of the internal data structures (compared to the utensils) which makes your area algorithm.

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
