javascript - Intersection point of two lines in leaflet -

-

i want intersection point of 2 polylines in leaflet. have 2 lines given below :- 

var latlng1 = l.latlng(-7.9375, 4.46354); var latlng2 = l.latlng(-7.96875, 16.11979); var latlongs1 = [ latlng1, latlng2 ]; var polyline1 = l.polyline(latlongs1, {     color : 'red' }).addto(map);   var latlng3 = l.latlng(-3.5625, 9.31719); var latlng4 = l.latlng(-12.125, 9.50469); var latlongs2 = [ latlng3, latlng4 ]; var polyline2 = l.polyline(latlongs2, {     color : 'blue' }).addto(map);

i can bounds , latlongs of endpoints of these lines. can't contiguous array of latlongs of line. there way ?

if don't program logic, there small , easy use library called turf provides several geoprocessing algorithms. can use 1 of algorithms independent of rest of library.

the lineintersects module want.

var intersection = turf.lineintersect(polyline1.togeojson(), polyline2.togeojson()); var intersectioncoord = intersection.features[0].geometry.coordinates;

also can check the source code of module inspiration.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
