The latest business development QR code recognition function, this function, in many applications, such as long press image identification QR code, if there is a recognizable QR code in the picture, you can add an option to identify the two-dimensional code. So how to implement this function. Here is actually very simple, the first two-dimensional code to identify the image, the recognition results returned when the judge whether there are two-dimensional code, there is an increase in the identi

there are two dimensional code, then there must be a one-dimensional code. One dimensional code. The most common is the bar code behind Food books. The barcode originated with the the 1940s, later in 1970 the UPC code was invented and began to be widely used with food packaging. The specific introduction can look at Baidu encyclopedia one dimensional code. The two-dimensional code is essentially similar to a one-dimensional code, just like a one-dimensional array and a two-dimensional arra

Here to introduce the next two-dimensional code introduction The two-dimensional code (2-dimensional bar code) is a Black-and-white graphic recording data symbol information which is distributed in a plane (two-dimensional direction) by a certain geometry. The concept of "0", "1" bit flow that forms the basis of the internal logic of the computer is cleverly utilized in code compilation, Uses a number of geometric shapes corresponding to the binary to represent literal numeric information. Auto

In order to complete the homework assigned by the teacher, we investigated the open source two-dimensional code recognition library. I only checked the zxing, Zbar, which zxing in my machine compile debugging pass, but the effect is not ideal, so changed the Zbar use. (My small partner found the open Source Library of Zxing Mobile end, and debug successfully, I w

I'll teach you step-by-step. Generate two-dimensional code with Java design In the era of the Internet of things, two-dimensional code is a very important thing, and now no matter what things must be a two-dimensional code signs, lest outdated, the cops did not use two-dimensional code to identify. Perhaps one day zoning card or hukou will be used to identify the two-dimensional code. Today's whim, see others for their blog added two-dimensional code, I also want to do a test. Mainly used to a

Insert picture in QR two-dimensional code Two-dimensional code finally fire, now the streets and the size of the ads on the two-dimensional code tags are everywhere, and most of them are not simple two-dimensional code, but the middle of the two-dimensional icon of the two-dimensional code. I did a previous use of Google Open source project zxing implementation of two-dimensional code, one-dimensional code encoding and decoding of the program and op

The simplest scan generates a two-dimensional code One Goal,one passion! Now the app scan two-dimensional code is almost standard, and scanning two-dimensional code demo is a dime a mile. But almost all of them are big pieces of copy many classes. And it is very cumbersome to use. I've been very bad at it all the time. And sometimes it's not used. It finally simplifies one of the most simple demos I've ever seen in my own time. 1th Step: Prepare for work-– of course,
