In computer graphics, the relative horizontal and vertical sizes. For example, if a graphic has an aspect ratio of 2:1, it means that the width is twice as large as the height. When resizing graphics, it is important to maintain the aspect ratio to avoid stretching the graphic out of proportion.
The term is also used to describe the dimensions of a display resolution. For example, a resolution of 800×600 has an aspect ratio of 4:3.
Aspects in aspect-oriented programming (AOP) package advice and pointcuts into functional units in much the same way that object-oriented programming uses classes to package fields and methods.
- aspherical surface
A lens surface with more than one radius of curvature (i.e., the surface does not form part of a sphere). The aspherical elements of a lens help compensate for many lens aberrations common in simpler lens designs. Aspherical elements are particularly important for wide-angle lenses, since they are prone to distortion. See “A Quick Guide […]
A program that translates programs from assembly language to machine language.
All of the files that comprise an application, including the resource, security management, versioning, sharing and deployment information. An assembly may appear as a single DLL or EXE file, or as multiple files, and is roughly the equivalent of a COM module.
- Assembly Language
)A programming language that is once removed from a computer’s machine language. Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use namesinstead of numbers. Each type of CPU […]
