Functions

Each callback receives an event with the following properties, if available:

message[string]: The error message

result[object]: The content of the barcode
data[object]: The parsed fields associated with the contentType

Properties

Ti.Barcode.allowRotation[boolean]

Value that indicates if the barcode capture should analyze captured images in either portrait or landscape device orientation. (Warning: Analyzing both the captured image and the rotated version(s) of the image will increase the processing time of the capture.)
