Types

type QrSVG

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

QrSVG holds the data related to the size, location, and block size of the QR Code. Holds unexported fields.

func NewQrSVG

func NewQrSVG(qr barcode.Barcode, blockSize int) QrSVG

NewQrSVG contructs a QrSVG struct. It takes a QR Code in the form of barcode.Barcode and sets the "pixel" or block size of QR Code in the SVG file.

func (*QrSVG) SetStartPoint

func (qs *QrSVG) SetStartPoint(x, y int)

SetStartPoint sets the top left start point of QR Code. This takes an X and Y value and then adds four white "blocks" to create the "quiet zone" around the QR Code.

func (*QrSVG) StartQrSVG

func (qs *QrSVG) StartQrSVG(s *svg.SVG)

StartQrSVG creates a start for writing an SVG file that only contains a barcode. This is similar to the svg.Start() method. StartQrSVG should only be used if you only want to write a QR code to the SVG. Otherwise use the regular svg.Start() method to start your SVG file.

func (*QrSVG) WriteQrSVG

func (qs *QrSVG) WriteQrSVG(elem *svg.SVG) error

WriteQrSVG writes the QR Code to SVG.

type Rect

type Rect struct {
	X int
	Y int
	W int
	H int
}

Rect 矩形.

type Rects

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

Rects 一组矩形.

func NewRects

func NewRects() *Rects

NewRects 新建矩形数组.

func (*Rects) Add

func (r *Rects) Add(rects ...*Rect)

Add 增加矩形.

func (*Rects) Compress

func (r *Rects) Compress() []*Rect

Compress 压缩.

func (*Rects) Len

func (r *Rects) Len() int

Len is the number of elements in the collection.

func (*Rects) Less

func (r *Rects) Less(indexI, indexJ int) bool

Less reports whether the element with index i should sort before the element with index j.

func (*Rects) Swap

func (r *Rects) Swap(i, j int)

Swap swaps the elements with indexes i and j.
