In the previous article, we mentioned the separation method for scanning a document that is "separation method to scan a document (1) - Dynamic Web TWAIN: How to use a blank page as a separator scanned documents" . Jiangzai article describes a method of scanning a document separation - the use of bar code / two-dimensional code as the separator of the scanned document.
This function can be realized through Dynamic Web TWAIN Barcode Reader and its add-ons.
Scenarios
Generally, a bar code or two-dimensional code has three modes about separate documents, as shown below.
- Mode 1: barcode / 2D code distributed on the first page of each document.
- Mode 2: barcode / 2D code distributed in the previous page of each document, that is similar to the blank page break.
- Mode three: bar code / two-dimensional code on each page of the document distributed to separated by the bar code / two-dimensional code recognized different values, the same code page values classified as the same document.
solution
According to three separate modes, Dynamsoft company has provided an online demo for online testing. If desired local testing, can be downloaded to the presentation, sample code after deployment test locally.
This article only referred to the document separation mode three kinds of bar code / two-dimensional code has some limitations, does not mean that the product can only achieve these three modes. If you need another separate mode, welcome to discuss the message.
