Display aspect ratio is referred to as Dar, which is a proportional relationship when displayed at a wide height.In the FFmpeg command, you can set it through-aspect. In practical applications, this parameter is often recommended and not used by each player. For example: I transcoding a resolution of 640x480 video, its display ratio is set to 10:3 with VLC play, the proportion of video display is 10:3, but

ASPECTJ is a tangent-oriented framework that extends the Java language, defines the AOP syntax,Ability to provide code weaving at compile time, so it has a dedicated compiler to generate class files that conform to bytecode byte coding specificationsMake sure to use JDK 5.0 or later.01.

Defined:AOP is an abbreviation for aspect oriented programming, meaning: aspect-oriented programming , by Precompiling method and run-time dynamic agent to realize the unified maintenance of the program functions of a technology. Development:AOP is OOP is a hotspot in software development and spring an important part of the framework is functional programming of a derivative model. Role:AOP enables you to i

surface, this sentence should be well understood, we draw the longitudinal process into a straight line, but the same part to the green prominent, such as the left, and AOP equivalent to the same place even a horizontal line, such as the right, this picture is not good, Everyone knows what it means.This verification user this sub-process becomes a line, can also be understood as a section, aspect meaning I think is the

What is Aspect-oriented programming?In software development, features distributed in multiple places in applications are becoming a cross-cutting concern.This section provides another option to replace inheritance and delegation, and is clearer and more concise in many scenarios. While using Aspect-Oriented Programming, we still define general functions in one place, but we can define this function and the

to send to the server object receiver chain, and finally objectterminatorsink sends the message to stackbuildersink. (The operation and caller of the four sinks are related to the location of the called party and the interaction between the four sinks. If you want to know more about them, you can write code for one-to-one testing .) Ii. Three implementations Implement. Net AOP (Aspect-Oriented Programming) using message mechanism -- Implement thr

Some of the concepts that AOP involves: Aspect: The abstraction of crosscutting concerns is a tangent, similar to a class, except that the focus of the two is different, and the class is an abstraction of the feature of the object, while the tangent is the abstraction of the crosscutting concern.Joinpoint (connection point): The so-called connection point refers to those points that are intercepted. In spring, these points refer to methods because spr

The literal meaning of scale and aspect in the contentMode of UIView, uiviewcontentmode Scale means scaling. If it appears in contentMode, it is necessary to change the image size.Aspect means the aspect ratio. In contentMode, it means to keep the aspect ratio of the image and keep the image unchanged. Scale aspect

Scale means: Scaling, appearing in Contentmode, is about changing the size of the graph.Aspect means that the aspect ratio, in the contentmode meaning is to maintain the aspect ratio of the graph, keep the picture not deformed.Scale aspect Fill: while maintaining the aspect ratio (
