Sample code

// Copy image buffer from camera into "pixel".
int width;
int height;
unsigned char *pixel = (unsigned char*)malloc(sizeof(unsigned char) * width * height);

// codeInfoStorage receives the result of visual code recognition.
CRCodeInfoStorage *codeInfoStorage = CRCreateCodeInfoStorage();

// storage to save visual code templates.
CRCodeImageTemplate *codeImageTemplateStorage = CRCreateCodeImageTemplateStorage();

// make template to recognize visual codes.
int c_width;
int c_height;
unsigned char *c_p = (unsigned char*)malloc(sizeof(unsigned char) * c_width * c_height);

/* read images of visual codes you want to recognize */

CRCodeImageTemplate *template = CRCreateCodeImageTemplate(c_p, c_width, c_height);
template->code = codeNumber;
template->size = codeSize;
CRCodeImageTemplateStorageAddNewTemplate(codeImageTemplateStorage, template);
free(c_p);

// Start extraction
CRChainCodeStorage *storage = CRCreateChainCodeStorageByParsingPixel(pixel, width, height);
CRChainCodeStorageDetectCornerWithLSM(storage);
CRCodeInfoStorageAddCodeInfoByExtractingFromChainCode(codeInfoStorage, storage, valueBuffer, width, height, codeImageTemplateStorage);

// Release
CRReleaseChainCodeStorage(&storage);
CRReleaseCodeInfoStorage(&codeInfoStorage);
free(pixel);
