1. Full automatic mode is available for beginners. In full automatic mode, you can take good photos without professional technology. 2. The main factor determining the image quality is the sensor size. The sensor area of Nikon J1/V1 is 116mm,The sensor area of Panasonic gf3 is 225mm,Olympus has a sensor area of 225mm square meters (produced by Panasonic ),The sensor area of Sony NEX series is 365mm,The sensor area of the

Php magic method-attribute overload method, php magic attribute overload Php has a magical class of methods. These methods are reserved and are generally not explicitly called outside. They start with a double underscore, they are called Magic Methods ). Php officially does not recommend defining other methods that start with a double underline. This section introduces the method for overloading attributes: get/set/isset/unset. public void __set ( string $name , mixed $value )public mixed __get

When performing class name operations on SVG elements, it is found that the classname is an object, so a series of bugs are reported. The first thought is to add the setclasses and getclasses two lower-level methods. The corresponding code becomes: VaR rclass =/\ s +/G Function getclasses (node) {If (node node. classname) {var classes = node. classname // the SVG Element returns a svganimatedstring object if ("baseval" in classes) {classes = classes. baseval} return classes. split (rclass)} ret

Understanding the implementation mechanism of Classes In JavaScript, you can use the function keyword to define a "class" and how to add members to the class. All variables or methods referenced by this pointer in a function become members of the class, For example: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> Function CLS (){ VaR Str = " ABC " ; This . Txt = STR; This . Displ

When we understand the Python __new__ method, we can also use it to do some other interesting things, such as implementing the single case pattern (singleton) in the design pattern. Because the process that the class produces after each instantiation is controlled by __new__, so we can implement the Singleton mode very simply by overloading the __new__ method. First look at how to implement a single case pattern in Python3: code is as follows copy code Class
