PDF417 Image Quality
collinforrester

We’re trying to use this API in our app to let the users take pictures of barcodes and have them decoded. We don’t have a way of enforcing the quality of the images they take so do you have any tips that will help the success rate of decoding barcodes?
Also, if we send a request to be decoded and the picture is bad enough that the server response is empty, does that still count as a “use” for the day/bill us?

Colin,
thanks for your interest. Our current policy is to only charge for successful decoding: if the picture is bad you won’t get charged. We haven’t had an issue in the past but we may change this policy if we find that failed requests are consuming significant resources
There really isn’t specific advice on image capture: clear, focused, well lit images are best, really. Clear, focused steady pictures are best: our barcode decoding is rotation-invariant, so we generally don’t need you to align the image in any particular axis.
Femi.
