示例1: _hit_point
protected _hit_point(geometry: PointGeometry): Selection {
/* Check if the point geometry hits this line glyph and return an object
that describes the hit result:
Args:
* geometry (object): object with the following keys
* sx (float): screen x coordinate of the point
* sy (float): screen y coordinate of the point
* type (str): type of geometry (in this case it's a point)
Output:
Object with the following keys:
* 0d (bool): whether the point hits the glyph or not
* 1d (array(int)): array with the indices hit by the point
