GoZBar
Fork of https://github.com/PeterCxy/gozbar due to API breaking changes.
ZBar bindings for golang. Only scanner supported.
Read the ZBar documentations for explanations on constants and arguments.
The ZBar library must be installed for this to compile.
Example JPEG Scan.
func TestPhoto(t *testing.T) {
const expectedStr = "http://www.searchenginestrategies.com/sanfrancisco/share.html"
f, err := os.Open("./testdata/photo.jpg")
if err != nil {
t.Fatal(err)
}
i, err := jpeg.Decode(f)
if err != nil {
t.Fatal(err)
}
img := FromImage(i)
s := NewScanner()
err = s.SetConfig(0, CFG_ENABLE, 1)
if err != nil {
t.Fatal("error setting config", err)
}
err = s.Scan(img)
if err != nil {
t.Fatal("error scanning", err)
}
defer s.Destroy()
img.First().Each(func(str string) {
if str != expectedStr {
t.Fatalf("expected [%s] got [%s]", expectedStr, str)
}
})
}

Types ¶
type Image ¶
type Image struct {
// contains filtered or unexported fields
}
Image contains a zbar image and the grayscale values.
func FromImage ¶
FromImage will create an ZBar image object from an image.Image. To scan the image, call a Scanner.
type Scanner ¶
type Scanner struct {
// contains filtered or unexported fields
}
Scanner contains a reference to zbar scanner.
func (*Scanner) SetConfig ¶
func (s *Scanner) SetConfig(symbology C.zbar_symbol_type_t, config C.zbar_config_t, value int) error
SetConfig gives the zbar scanner the configuration to run.. Read the ZBar docs for details.
type Symbol ¶
type Symbol struct {
// contains filtered or unexported fields
}
Symbol is a wrapper around a zbar symbol.
func (*Symbol) Each ¶
Each will iterate over all symbols after this symbol. passing them into the provided callback
func (*Symbol) Type ¶
func (s *Symbol) Type() C.zbar_symbol_type_t
Type returns the symbol type. Compare it with types in constants to get the accurate symbol type.
