Before iOS7, QR code and barcode scanning were implemented in iOS, and we know there are two big open source components Zbar and zxing. We've all worked on both of these components, and here's a summary of their shortcomings:
Zbar
Zbar on the sensitivity of the scan, and the use of memory relative to the
It is not uncommon to generate a QR code by using extensions on chrome. This extension can be implemented by using the QR code generator, and such extensions can appear in any search of Chrome Web store. However, it is rare to read the QR
Basic Application reference for Jasperreport:Ireport+jasperreport+applet Report PrintingThe idea and process of using ireport+jasperreport to deal with Chinese QR code is applied.
Show the two-dimensional barcode in the report.
Adaptive Scanner Action processing (Chinese escape).
Combine JS to use barcode
Business Scenarioswhen a QR code scan is implemented ( with a zbar), sometimes the entire scanned image needs to be stored quietly, and (as Charles has some perverted business) that means a panoramic picture of the scanned picture. So how is the code implemented? I went to StackOverflow finally found the way to achieve
