Functions ¶

func Minify ¶

func Minify(m *minify.M, w io.Writer, r io.Reader, params map[string]string) error

Minify minifies SVG data, it reads from r and writes to w.

Example ¶

m := minify.New()
m.AddFunc("image/svg+xml", Minify)
m.AddFunc("text/css", css.Minify)

if err := m.Minify("image/svg+xml", os.Stdout, os.Stdin); err != nil {
	panic(err)
}

Output:

Types ¶

func (*Minifier) Minify ¶

func (o *Minifier) Minify(m *minify.M, w io.Writer, r io.Reader, _ map[string]string) error

Minify minifies SVG data, it reads from r and writes to w.

type PathData ¶ added in v2.1.0

type PathData struct {
	// contains filtered or unexported fields
}

func NewPathData ¶ added in v2.1.0

func NewPathData(o *Minifier) *PathData

func (*PathData) ShortenPathData ¶ added in v2.1.0

func (p *PathData) ShortenPathData(b []byte) []byte

ShortenPathData takes a full pathdata string and returns a shortened version. The original string is overwritten. It parses all commands (M, A, Z, ...) and coordinates (numbers) and calls copyInstruction for each command.

type PathDataState ¶ added in v2.1.0

type PathDataState struct {
	// contains filtered or unexported fields
}

type Token ¶

type Token struct {
	xml.TokenType
	Hash    svg.Hash
	Data    []byte
	Text    []byte
	AttrVal []byte
}

Token is a single token unit with an attribute value (if given) and hash of the data.

type TokenBuffer ¶

type TokenBuffer struct {
	// contains filtered or unexported fields
}

TokenBuffer is a buffer that allows for token look-ahead.

func NewTokenBuffer ¶

func NewTokenBuffer(l *xml.Lexer) *TokenBuffer

NewTokenBuffer returns a new TokenBuffer.

func (*TokenBuffer) Attributes ¶

func (z *TokenBuffer) Attributes(hashes ...svg.Hash) ([]*Token, *Token)

Attributes extracts the gives attribute hashes from a tag. It returns in the same order pointers to the requested token data or nil.

func (*TokenBuffer) Peek ¶

func (z *TokenBuffer) Peek(pos int) *Token

Peek returns the ith element and possibly does an allocation. Peeking past an error will panic.

func (*TokenBuffer) Shift ¶

func (z *TokenBuffer) Shift() *Token

Shift returns the first element and advances position.
