Animated GIF

An animated GIF is a a single graphic file that contains a series of images which are displayed sequentially to give the illusion of movement or change over time. Animation is best used sparingly on text intensive webpages. Movement may add a dynamic feel to content.  A GIF file is a compressed image with only 256 colours.  GIF stands for The Graphics Interchange Format

JPEG IMAGE

Jpeg file is used for high quality images. It contains approximately 24 million colours, and is typically used for photographs. Alot of cameras use jpeg. 'JPEG' stands for 'Joint Photographic Experts Group' JPEG file is a compressed file.

PIXEL

The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. One pixel has 3 different colours in it (green, red and blue), and when they all come together they make a white light.

BMP FILE

In computer graphics, a bitmap (BMP) or pixmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits. It is a large file because it is not compressed and it is used in windows. BMP files are becoming less and less common

FLIP

A FLIP takes place when a shape is flipped across a line and faces the opposite direction. Because the shape ends up facing the opposite direction, it appears to be reflected, as in a mirror. A FLIP can also take place across a line in an up and down direction. In fact, a flip can take place in any direction. All you need to remember is the shape ends up facing the opposite direction and it appears to be reflected, as in a mirror.

VIDEO CARD

Video cards provide your computer with memory – a bit like RAM – to generate on-screen images. The more memory on the card, the more detailed and more colourful the images it can display. If your work is very visual, like photography, design or video editing, you’ll want a better than average video card.

CROP

In computer graphics, to cut off the sides of an image to make it the proper size or to remove unwanted parts. Cropping creates a new image by selecting a desired rectangular portion from the image being cropped. The unwanted part of the image is discarded. Image cropping does not reduce the resolution of the area cropped. Best results are obtained when the original image has a high resolution. A primary reason for cropping is to improve the image composition in the new image.

MIRROR

 

FRAMES PER

SECOND

FPS (Frames Per second) is the speed at which an animation, film or video is displayed. The frames per second setting for an animation should be at least 12 to create the illusion of movement.

FRAME

Graphics and desktop publishing programs also use frames. In these programs, frames are rectangular areas meant for inserting graphics and text. They allow users to place objects wherever they want to on the page. In video and animation, frames are individual pictures in a sequence of images. For example, a Flash movie you see on the Web may play 12 frames per second, creating the appearance of motion. Most video is shot at 24 or 30 frames per second, or FPS. FPS is often measured in 3D games as a way of checking how fast the graphics processor of a computer is.

MORPH

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. Most often it is used to depict one person turning into another through technological means or as part of a fantasy or surreal sequence.

CPU

CPU is the abbreviation for central processing unit. The CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system

DPI

A measure of the resolution of a printer is called DPI or dots per inch. It properly refers to the dots of ink or toner used by an imagesetter, laser printer, or other printing device to print your text and graphics. In general, the more dots, the better and sharper the image. DPI is printer resolution. DPI is not image resolution although frequently used that way.

RESOLUTION

Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers and bit-mapped graphic images For graphics monitors the screen resolution signifies the number of dots pixels on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels.

FILE EXTENSION

A file extension (or simply "extension") is the suffix at the end of a filename that indicates what type of file it is. For example, in the filename "myreport.txt," the. TXT is the file extension. It indicates the file is a text document. Some other examples include.DOCX, which is used for Microsoft Word documents, and .PSD, which is the standard file extension for Photoshop documents. Most file extensions are 3 letters

compression

A means of reducing the amount of data to be transmitted or stored. Compression is possible since there always is some amount of data redundancy or there may be a predictable flow to the data.

FRAME BUFFER

The portion of memory reserved for holding the complete bit-mapped image that is sent to the monitor. Typically the frame buffer is stored in the memory chips on the video adapter.

COLOUR DEPTH

Colour depth is the number of bits used to represent the colour of a single pixel.
