Functions ¶

func ParseColor ¶

func ParseColor(str string) stdcol.Color

func ParseStyle ¶

func ParseStyle(str string, attrs map[string]string)

func ParseTransform ¶

func ParseTransform(str string) *g2d.Aff3

func ParseUrlId ¶

func ParseUrlId(str string) string

func ParseValue ¶

func ParseValue(str string) float64

func ParseValueUnit ¶

func ParseValueUnit(str string) (float64, string)

Types ¶

type SVG ¶

type SVG struct {
	Xfm  *g2d.Aff3               // Path transform
	Clip map[string]*g2d.Shape   // Clip path ids to clip shapes
	Defs map[string]*xml.Element // Element ids to elements
	Rend *g2d.Renderable         // Renderable paths and fillers
}

SVG contains the current context - the image being drawn into, the style and view transforms, and the defined clip paths and shapes.

func Draw ¶

func Draw(dst draw.Image, dom *xml.Element) *SVG

Draw is a convenience function to render the svg dom into an image. The svg is scaled to the image size.

func Image ¶

func Image(dom *xml.Element) (*stdimg.RGBA, *SVG)

Image renders the svg dom into an empty image with the same bounds as the dom.

func NewSVG ¶

func NewSVG() *SVG

func (*SVG) CircleElt ¶

func (svg *SVG) CircleElt(elt *xml.Element)

func (*SVG) ClipPathElt ¶
