QR code scan Android Zxing image stretching Solution
Zxing is a QR code scanning project provided by google.
By default, the image is stretched after the screen is converted to a portrait.
The solution is as follows:
Zxing modifies

Android Zxing QR code scanning image stretching,
In this project, the QR code scanning is integrated with zxing, and the image on the scanning interface is obviously stretched and deformed.
Based on past experience, this problem is generally caused by misplacement of x and Y
This is a function of the document management system. Many documents do not have electronic files during document management. The scanner is used.
The system integrates a scanner. We can scan documents and edit scanned images in the software. It can be saved as an image, or multiple images can be used to generate PDF files.
Documentation, zip compressed documentation, etc.

#include Color reduction is achieved by taking advantage of a integer division that floors the division result to the nearest Lowe R integer:data[i]= Data[i]/div*div + div/2;The reduced color could has also been computed using the modulo operator which brings us to the nearest multiple of Div ( The 1D reduction Factor):data[i]= Data[i]–data[i]%div + div/2;But this computation are a bit slower because it requires reading each pixel value twice.Another option would is to use bitwise operators.

PrefaceDocker is an open source, Docker.inc, container engine project based on lightweight virtualization technology that is based on the go language and complies with the Apache 2.0 protocol. With layered mirroring standardization and kernel virtualization technology, Docker enables application developers and operations engineers to publish applications across platforms in a unified manner, and provides resource-isolated application runtimes with vir
Docker Quick Start series (1): Image concepts and related operationsWhat is Docker?
One of the first questions I encountered about docker is what can docker do? What is docker? Here, let's take a look at Baidu encyclopedia's brief

Docker mirroring (image) is similar to a virtual machine image, and can be interpreted as a read-only template for the Docker
All say container Dafa is good, but if there is no Docker image, how boring is Docker.Do you still remember the image you pulled from the Docker hub when you first contacted Docker? On the basis of that Virgin Mirror, you run the container of the life of the Virgin. The corn
Use Docker Registry to quickly build a private image repository1. Background
In Docker, when we run docker pull xxx, we may be curious. Where will Docker find and download the image?
It is actually searched from the address regist
Docker Warehouse Warehouses are places where image files are centrally stored. Sometimes the warehouse and the warehouse registration server (Registry) are confused, not strictly differentiated. In fact, the warehouse registration server often holds multiple warehouses, each of which contains multiple mirrors, each with a different label (tag).a Docker Registry c
Docker deploys the SpringBoot project to integrate the Redis image for access counting sample code, dockerspringboot
The final result is as follows:
About a few steps

In a Docker infrastructure, the Docker containers are created using images. Containers are instances that are created when the image files are executed. These images can is of Web servers, mail servers, applications, and so on.

Docker can be used in the operating system to separate a number of independent areas (container/container), the basic isolation between the containers, and can have their own separate system configuration, software, etc., the software between the various containers do not interfere with each other basically. Containers configured on Docker can be moved to other computers at will.Docker is a great way to kee
