zbar_get_symbol_name⚠ | |
zbar_image_create⚠ |
constructor * @returns a new image object with uninitialized data and format. This image should be * destroyed using zbar_image_destroy as soon as the application is finished with it. |
zbar_image_destroy⚠ |
destructor * all images create by or returned to the application should be destroyed using this function. * when an image is destroyed, the associated data cleanup handler will be involed if * available. |
zbar_image_first_symbol⚠ | |
zbar_image_free_data⚠ | |
zbar_image_get_data⚠ | |
zbar_image_get_format⚠ | |
zbar_image_get_height⚠ | |
zbar_image_get_width⚠ | |
zbar_image_ref⚠ |
image reference count manipulation * increment the reference count when you store a new reference to the image. decrement when * the reference is no longer used. do not refer to the image any longer once the count is * decremented. |
zbar_image_scanner_create⚠ |
constructor * |
zbar_image_scanner_destroy⚠ |
destructor * |
zbar_image_scanner_get_results⚠ |
retrieve decode results for the last scanned image. * @returns the symbol set result container or NULL if no results are available * @note the symbol set does not have its reference count adjusted; ensure that the count is * incremented if the results may be kept after the next image is scanned. |
zbar_image_scanner_parse_config⚠ |
parse configuration string using zbar_parse_config() and apply to image scanner using * zbar image_scanner_set_config() * @returns 0 for suhttps://www.google.com/search?tbm=isch&source=hp&biw=1468&bih=666&ei=EqlJWtD-MKm4jwSM65WADA&q=qr+code&oq=qr+code&gs_l=img.3..0l10.760.1792.0.1926.8.5.0.3.3.0.118.376.3j1.4.0....0...1ac.1.64.img..1.7.411.0...0.6p2UJmijeU0#imgrc=xc-lmcIMuckakM:ccess, non-0 for failure |
zbar_image_scanner_set_config⚠ |
set config for indicated symbology (0 for all) to specified value * @returns 0 for success, non-0 for failure (config does not apply to specified * symbology, or value out of range |
zbar_image_scanner_set_data_handler⚠ |
setup result handler callback * the specified function will be called by the scanner whenever new results are available from * a decoded image. pass a NULL value to disable callbacks. * @returns the previously-registered handler |
zbar_image_set_data⚠ | |
zbar_image_set_format⚠ | |
zbar_image_set_size⚠ | |
zbar_parse_config⚠ |
parse a configuration string of the form "[symbology.]config[=value]". * the config must match one of the recognized names. * the symbology, if present, must match one of the recognized names. * if symbology is unspecified, it will be set to 0. * if value is unspecified, it will be set to 1. * @returns 0 if the config is parsed successfully, 1 otherwise |
