Types ¶
type Hash ¶
type Hash uint32
Hash defines perfect hashes for a predefined list of strings

Unique hash definitions to be used instead of strings
func ToHash ¶
ToHash returns the hash whose name is s. It returns zero if there is no such hash. It is case sensitive.
func (Hash) String ¶
String returns the hash' name.
type Minifier ¶
type Minifier struct {
KeepComments bool
Precision int // number of significant digits
Inline bool
// contains filtered or unexported fields
}
Minifier is an SVG minifier.
func (*Minifier) Minify ¶
Minify minifies SVG data, it reads from r and writes to w.
type PathData ¶
type PathData struct {
// contains filtered or unexported fields
}
PathData represents a path data string.
func NewPathData ¶
NewPathData returns a new PathData.
func (*PathData) ShortenPathData ¶
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 ¶
type PathDataState struct {
// contains filtered or unexported fields
}
PathDataState is the state of the current path.
type Token ¶
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(r *parse.Input, l *xml.Lexer) *TokenBuffer
NewTokenBuffer returns a new TokenBuffer.
func (*TokenBuffer) Attributes ¶
func (z *TokenBuffer) Attributes(hashes ...Hash) []*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.
