Barcode Xpress for Node.js is an SDK designed for barcode recognition. Barcode Xpress for Node.js performs the task of recognizing barcodes in a digital image.

• An image stored on disk can be analyzed by providing the file path to that image’s location. Other possible inputs are jimp objects and buffers.
• Supported file types are: jpeg, png, bmp, tiff, and gif.

The API will detect and analyze any barcodes found within the image and store the output data into a results array object. This object contains the area, type, value, corners and confidence.
