Guides for 90 degree

[mohammedzamakhan]

Is there a way where I can have extra guide to show 90 degree to the user when he is in the quadrant of 45degrees to the last line.

I do not want leaflet.pm to add it, but if I can know if there is a event or something that can help me build it myself.

the quadrants would be like this, but we would not be showing that in the UI

mh good question. I would try it like this:

map.on('pm:drawstart', function(e) {
    var layer = e.workingLayer;
    layer.on('pm:vertexadded', function(e) {
        // e includes the new vertex, it's marker
        // the index in the coordinates array
        // the working layer and shape
    });
});

in vertexadded you should get the latest coordinate that is added to the shape. You can place your guide in reference to it. Does this help?

I want the 90 degree guide only while dragging, these events are only called after you add.

Could you place it at the cursor after drawstart?

When the angle between the blue dotted line and the violet dotted like is really less, we also want it to snap to the purple perpendicular guide.

Ok sounds like you’d need an additional event. Shouldn’t be that hard. Marked as feature request! Feel free to submit a PR if you would like to help
