Types

type Element

type Element struct {
	Name       string
	Attributes map[string]string
	Children   []*Element
	Content    string
}

Element is a representation of an SVG element.

func New

func New(source io.Reader) (*Element, error)

New creates an Element instance from an SVG input.

func (*Element) Equal

func (e *Element) Equal(o *Element) bool

Equal checks if two elements are equivalent.

func (*Element) Render

func (e *Element) Render(w io.Writer) error

Render creates an SVG output from the element. Returns an error if the element is empty.

type Path

type Path struct {
	Commands []*PathCommand
}

Path is a collection of all the subpaths in path data attribute.

func NewPath

func NewPath(raw string) (*Path, error)

NewPath takes value of a path data attribute transforms it into a series of commands containing the appropriate parameters.

func (*Path) Equal

func (p *Path) Equal(o *Path) bool

Equal compares two paths.

func (*Path) Subpaths

func (p *Path) Subpaths() []*Path

Subpaths computes all subpaths from a given path. 'Z' command is excluded from the resulting paths.

type PathCommand

type PathCommand struct {
	Symbol string
	Params []float64
}

PathCommand is a representation of an SVG path command. It contains the operator symbol and the command's parameters.

func (*PathCommand) Equal

func (c *PathCommand) Equal(o *PathCommand) bool

Equal compares two commands.

func (*PathCommand) IsAbsolute

func (c *PathCommand) IsAbsolute() bool

IsAbsolute returns true is the SVG path command is absolute.
