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
