Functions

func Encode

func Encode(data string, securityLevel byte, targetRowHeight, targetColumns int) (image.Image, error)

Encodes the given data as PDF417 barcode. securityLevel should be between 0 and 8. The higher the number, the more additional error-correction codes are added.

Types

type BitList

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

BitList is a list that contains bits

func NewBitList

func NewBitList(capacity int) *BitList

NewBitList returns a new BitList with the given length all bits are initialize with false

func (*BitList) AddBit

func (bl *BitList) AddBit(bits ...bool)

AddBit appends the given bits to the end of the list

func (*BitList) AddBits

func (bl *BitList) AddBits(b int, count byte)

AddBits appends the last (LSB) 'count' bits of 'b' the the end of the list

func (*BitList) AddByte

func (bl *BitList) AddByte(b byte)

AddByte appends all 8 bits of the given byte to the end of the list

func (*BitList) GetBit

func (bl *BitList) GetBit(index int) bool

GetBit returns the bit at the given index

func (*BitList) GetBytes

func (bl *BitList) GetBytes() []byte

GetBytes returns all bits of the BitList as a []byte

func (*BitList) IterateBytes

func (bl *BitList) IterateBytes() <-chan byte

IterateBytes iterates through all bytes contained in the BitList

func (*BitList) Len

func (bl *BitList) Len() int

Len returns the number of contained bits

func (*BitList) SetBit

func (bl *BitList) SetBit(index int, value bool)

SetBit sets the bit at the given index to the given value
