google.maps.IconSequence interface
Describes how icons are to be rendered on a line.
If your polyline is geodesic, then the distances specified for both offset and repeat are calculated in meters by default. Setting either offset or repeat to a pixel value will cause the distances to be calculated in pixels on the screen.
Properties
Type: boolean
If true, each icon in the sequence has the same fixed rotation regardless of the angle of the edge on which it lies. Defaults to false, in which case each icon in the sequence is rotated to align with its edge.
Type: Symbol
The icon to render on the line.
Type: string
The distance from the start of the line at which an icon is to be rendered. This distance may be expressed as a percentage of line's length (e.g. '50%') or in pixels (e.g. '50px'). Defaults to '100%'.
Type: string
The distance between consecutive icons on the line. This distance may be expressed as a percentage of the line's length (e.g. '50%') or in pixels (e.g. '50px'). To disable repeating of the icon, specify '0'. Defaults to '0'.
