Functions ¶

func BezierCurveSegment ¶

func BezierCurveSegment(p1, p2, p3, p4 *geo.Point, t0, t1 float64) (geo.Point, geo.Point, geo.Point, geo.Point)

Given control points p1, p2, p3, p4, calculate the segment of this bezier curve from t0 -> t1 where {0 <= t0 < t1 <= 1}. Uses De Casteljau's algorithm, referenced: https://stackoverflow.com/questions/11703283/cubic-bezier-curve-segment/11704152#11704152

func EscapeText ¶

func EscapeText(text string) string

func GetStrokeDashAttributes ¶

func GetStrokeDashAttributes(strokeWidth, dashGapSize float64) (float64, float64)

func SVGID ¶

func SVGID(text string) string

func SplitPath ¶

func SplitPath(path string, percentage float64) (string, string, error)

Splits an SVG path into two SVG paths, with the first path being ~{percentage}% of the path
