This article mainly introduces how php uses GD to create a height-to-height ratio thumbnail. it involves php's skills in operating images using the GD Library, for more information about how to use GD to create a thumbnail with A aspect ratio, see the example in this article. Share it with you for your reference. The details are as follows: /*** Create a thumbnail image from $inputFileName no taller or wider than* $maxSize. Returns the new image res

AOP, short for aspect oriented programming, is a continuation of OOP. It is a technology that dynamically and uniformly adds functions to the program without modifying the source code through the pre-compilation method and the dynamic agent at runtime, it looks at the structure of a program from a different perspective than OOP: Oop splits an application {Tagshow (Event)} "> The series is represented as objects of the inheritance relationship. AOP spl

Log statistics using AOP for Aspect-Oriented Programming on the Android platformRecently, I have thought of aop because I need to collect some app logs and don't want to call them everywhere. The procedure is as follows:1. Install the ajdt plug-in eclipse2. Set the cut point and implement the cut point execution method. The configuration in android is slightly different from that in server. The specific code is as follows: public

(); } } }Catch(IOException ioe ){ StringMessage = "IOError. Unable to find Business Unit records "; Logger. log (SEVERE, message, ioe ); ThrowNewRepositoryException (message, ioe ); } Logger. log (INFO, "Manager Records returned:" + businessUnits. size ()); ReturnBusinessUnits; } The above Code uses FileReader and BUfferedReader to read business data in the CSV file. The application repeatedly retrieves data from the resource file and then releases it after the operation is complet

AOP: Aspect-oriented to take the horizontal extraction mechanism, replacing the traditional vertical inheritance system repetitive code (performance monitoring, transaction management, security check, caching)AOP enables the isolation of parts of the business logic, which reduces the coupling between parts of the business logic, improves the reusability of the program, and improves the efficiency of development.Several core concepts of AOP ":1, crossc

the correct index. It also includes the use of bitmap and function based indexes. Ensure optimal Join operations: Some queries use nested LOOP join faster, some are hash join faster, others are sort-merge join faster. These rules seem simple, but they account for 90% of the SQL Tuning task, and they do not need to fully understand the internal workings of Oracle SQL. Here's a quick overview of the following Oracle SQL optimizations. Let's start with a brief look at Oracle's sort, and see how th

Aspect-oriented programming (AOP) is a bit interesting. You can add new functions without modifying the original code. Some js frameworks implement the AOP function, but sometimes we cannot rely on the framework to write programs (the framework may be bulky). We need to implement some functional modules that are suitable for us. The following is my own js AOP, which implements the before and after functions and is only for throwing bricks. The followi

Talk about Python's adorner pattern and aspect-oriented programming Let's talk about decorators today. The adorner is a well-known design pattern, which is often used in scenes where there is a demand for facets, with the classic insert log, performance test, transaction processing, and so on. Decorators are a great design for solving such problems, and with adorners, we can pull out a lot of the same code that is not relevant to the function

The Dojo/aspect module is an implementation of AOP in the Dojo framework. For a detailed explanation of AOP please read the other information separately, here is a brief review of the basic concepts of AOP: Facets (Aspect): In fact, the realization of common functions. such as log plane, permission plane, transaction plane, and so on. Notification (Advice): is the specific implementation of fac

Maybe you will wonder how the aopmethodattri instance is created and executed? 1. Pay attention to the output content of the vs2005 output window during compilation. You will see the following content. In fact, postsharp provides a msbuild task, which will be called every time we compile to execute some injection operations.Postsharp 1.0 [1.0.4.162]

AOP ideas and Aspect-Oriented Programming AOP is actually an extension of the gof four-person group design model.CodeIncrease the Coupling DegreeProgramThe flexibility and reusability of AOP is actually an implementation of the goal pursued by the design model. The so-called separation focus is to separate a common demand function from irrelevant classes. At the same time, it can make many classes share an action. Once the behavior changes, there is
