Name Type Description
options

Options.

Name Type Description
fill ol.style.Fill | undefined experimental

Fill style.
radius number experimental

Circle radius.
snapToPixel boolean | undefined experimental

If true integral numbers of pixels are used as the X and Y pixel coordinate when drawing the circle in the output canvas. If false fractional numbers may be used. Using true allows for "sharp" rendering (no blur), while using false allows for "accurate" rendering. Note that accuracy is important if the circle's position is animated. Without it, the circle may jitter noticeably. Default value is true.
stroke ol.style.Stroke | undefined experimental

Stroke style.
