Page Layout Definition Page layout refers to the arrangement of text, images, and other objects on a page. The term was initially used in desktop publishing (DTP), but is now commonly used to describe the layout of webpages as well. Page layout techniques are used to customize the appearance of magazines, newspapers, books, websites, and other types of publications. ..
GIF Definition Stands for “Graphics Interchange Format.” GIF is an image file format commonly used for images on the web and sprites in software programs. Unlike the JPEG image format, GIFs uses lossless compression that does not degrade the quality of the image. However, GIFs store image data using indexed color, meaning a standard GIF image can include a maximum of 256 colors. ..
MP3 Definition Stands for “MPEG Audio Layer-3.” MP3 is a compressed audio file format developed by the Moving Picture Experts Group (MPEG). A typical MP3 file sounds similar to the original recording, but requires significantly less disk space. MP3 files are often about one tenth the size of an uncompressed WAVE or AIFF file, which have the same audio quality as a CD. The ..
MPEG Definition Stands for “Moving Picture Experts Group.” MPEG is an organization that develops standards for encoding digital audio and video. It works with the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to ensure media compression standards are widely adopted and universally available. The MPEG organization has produced a number of digital media standards since its inception ..
Animated GIF Definition An animated GIF is a GIF file that includes multiple images or “frames.” These frames are played back in sequence when the file is opened or displayed in a web browser. The result is an animated clip or a short movie. The GIF file format includes a Graphics Control Extension (or “GCE block”), which enables a single ..
PNG Definition PNG, which can be pronounced “ping” or “P-N-G,” is a compressed raster graphic format. It is commonly used on the Web and is also a popular choice for application graphics. The PNG format was introduced in 1994, after the GIF and JPEG formats had already been around for several years. Therefore, PNG includes many of the benefits of both formats. For ..
Raster Graphic Definition Most images you see on your computer screen are raster graphics. Pictures found on the Web and photos you import from your digital camera are raster graphics. They are made up of grid of pixels, commonly referred to as a bitmap. The larger the image, the more disk space the image file ..
Vector Graphic Definition Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a ..
Bitmap Definition A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color. Together, these dots can be used to represent any type of rectangular picture. There are several different bitmap file ..
