The representation of graphical objects, such as lines, arcs, circles, and rectangles, with mathematical formulas. This method of describing objects enables the system to manipulate the objects more freely. In an object-oriented system, for example, you can overlap objects but still access them individually, which is difficult in a bit-mapped system. Also, object-oriented images profit from high-quality output devices. The higher the resolution of a monitor or printer, the sharper an object-oriented image will look. In contrast, bit-mapped images always appear the same regardless of a device’s resolution.
One of the most widely used formats for object-oriented graphics is PostScript. PostScript is a page description language (PDL) that makes it possible to describe objects and manipulate them in various ways. For example, you can make objects smaller or larger, turn them at various angles, and change their shading and color. A font described in PostScript, therefore, can easily be transformed into another font by changing its size or weight. Object-oriented fonts are called outline fonts, scalable fonts, or vector fonts.
Object-oriented graphics is also called vector graphics, whereas bit-mapped graphics is sometimes called raster graphics.
- Object-Oriented Programming
A type of programming in which programmers define not only the data type of a data structure, but also the types of operations (functions) that can be applied to the data structure. In this way, the data structure becomes an object that includes both data and functions. In addition, programmers can create relationships between one […]
Short for object role modeling, a conceptual database design methodology that allows the user to express information as an object and explore how it relates to other information objects.
A lexically scoped interpreted programming language that supports distributed object-oriented computing. Obliq computations can roam over the network, while maintaining network connections. In Obliq, there are no class hierarchies as every object is potentially and transparently a network object. An object may become accessible over the network either by the negotiation of a name server […]
In computers and technology the term obsolete means the hardware is no longer in use, even though it may still be in working order. It is a term associated with outdated designs that are no longer supported by the manufacturer.
- obsolete element
In HTML, any element (tags or code) that may not work in future versions of Internet browsers is considered an obsolete element.
