kandi X-RAY | geometer Summary
Geometer is a geometry library for Python that uses projective geometry and numpy for fast geometric computation. In projective geometry every point in 2D is represented by a three-dimensional vector and every point in 3D is represented by a four-dimensional vector. This has the following advantages:. Most of the computation in the library is done via tensor diagrams (using numpy.einsum). Geometer was originally built as a learning exercise and is based on two graduate courses taught at the Technical University Munich. After investing a lot of time in the project, it is now reasonably well tested and the API should be stable. The source code of the package can be found on GitHub and the documentation on Read the Docs.

QUESTION
I want to give users the ability to find out how far they are from a Point of Interest to the edge of a radius on a map. I would also like to convert that unit to kilometers, meter or nautical mile.
I understand that all polygons are drawn in meters.
I am using fromCircle to convert a circle to a geometer polygon. Please help me. I remember there was a getbound() function in openlayers 2 but i can not find it anymore to use to calculate the distance form the the point of interest or center of the map to the edge. I have searched through stackoverflow for days but can not find exactly what is need or the solution that worked with the new version of openlayers.
ANSWER
Answered 2020-Nov-25 at 20:23The distance from a point to the edge of a ctrcle is the distance from the point to the center of the circle minus the radius.
But OpenLayers has a getClosestPoint method which will work with any geometry:
QUESTION
I'm trying to use Spring's webflux to create an http endpoint to stream github users using Github's api. I tried to do what is described here and here but it seems that the expand is not fetching the second page of results from github's api. What am I doing wrong? Here's the code I currently have:
...ANSWER
Answered 2020-Jun-05 at 14:43The link header in the Github API provides the URI in an escaped format. The String you pass to client.get().uri() should be unescaped - so it escapes the escaped string, and you end up with a URL that returns nothing.
Instead, you probably want to use something similar to:
