Types ¶
type BitGrid ¶
type BitGrid struct {
// contains filtered or unexported fields
}
func Encode ¶
QR encode the content at the specified error correction level (ecLevel).
Example ¶
grid, err := Encode("Testing one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty.", ECLevelQ)
if err != nil {
return
}
f, err := os.Create("/tmp/qr.png")
if err != nil {
return
}
defer f.Close()
png.Encode(f, grid.Image(8))
Output:
func EncodeBytes ¶
QR encode the content at the specified error correction level (ecLevel).
func NewBitGrid ¶
func (*BitGrid) Image ¶
Return an image of the grid, with black blocks for true items and white blocks for false items, with the given block size and a default margin.
func (*BitGrid) ImageWithMargin ¶
Return an image of the grid, with black blocks for true items and white blocks for false items, with the given block size and margin.
type BitVector ¶
type BitVector struct {
// contains filtered or unexported fields
}
func (*BitVector) AppendBits ¶
