An animated GIF is a a singlegraphic file that contains a seriesof images which are displayedsequentially to give the illusion ofmovement or change over time.Animation is best used sparinglyon text intensive webpages.Movement may add a dynamicfeel to content.A GIF file is a compressed imagewith only 256 colours.GIF stands for The GraphicsInterchange Format
Jpeg file is used for highquality images. It containsapproximately 24 millioncolours, and is typicallyused for photographs. Alotof cameras use jpeg.JPEG stands for JointPhotographic ExpertsGroupJPEG file is a compressedfile.
The pixel (a word inventedfrom "picture element") is thebasic unit of programmablecolor on a computer display orin a computer image.One pixel has 3 differentcolours in it (green, red andblue), and when they all cometogether they make a whitelight.
In computer graphics, a bitmap (BMP) or pixmap is atype of memory organization or image file format usedto store digital images. The term bitmap comes fromthe computer programming terminology, meaning justa map of bits.It is a large file because it is not compressed and it isused in windows.BMP files are becoming less and less common
A FLIP takes place when a shape isflipped across a line and faces theopposite direction. Because the shapeends up facing the opposite direction,it appears to be reflected, as in amirror.A FLIP can also take place across a linein an up and down direction. In fact, aflip can take place in any direction. Allyou need to remember is the shapeends up facing the opposite directionand it appears to be reflected, as in amirror.
Video cards provide your computer with memory – a bitlike RAM – to generate on-screen images. The morememory on the card, the more detailed and more colourfulthe images it can display. If your work is very visual, likephotography, design or video editing, you’ll want a betterthan average video card.
In computer graphics, to cut off the sides of an image to make itthe proper size or to remove unwanted parts.Cropping creates a new image by selecting a desired rectangularportion from the image being cropped. The unwanted part ofthe image is discarded. Image cropping does not reduce theresolution of the area cropped. Best results are obtained whenthe original image has a high resolution. A primary reason forcropping is to improve the image composition in the newimage.
Graphics and desktop publishing programs also use frames.In these programs, frames are rectangular areas meant forinserting graphics and text. They allow users to place objectswherever they want to on the page.In video and animation, frames are individual pictures in asequence of images. For example, a Flash movie you see onthe Web may play 12 frames per second, creating theappearance of motion. Most video is shot at 24 or 30 framesper second, or FPS. FPS is often measured in 3D games as away of checking how fast the graphics processor of acomputer is.
Morphing is a special effect in motion pictures and animationsthat changes (or morphs) one image into another through aseamless transition. Most often it is used to depict one personturning into another through technological means or as part ofa fantasy or surreal sequence.
CPU is the abbreviation for central processing unit. TheCPU is the brains of the computer where mostcalculations take place. In terms of computing power,the CPU is the most important element of a computersystem
A measure of the resolution of a printer is called DPI or dotsper inch. It properly refers to the dots of ink or toner used byan imagesetter, laser printer, or other printing device to printyour text and graphics. In general, the more dots, the betterand sharper the image. DPI is printer resolution.DPI is not image resolution although frequently used that way.
Refers to the sharpness and clarity of an image. The term ismost often used to describe monitors, printers and bit-mapped graphic images For graphics monitors the screen resolution signifies thenumber of dots pixels on the entire screen. For example, a640-by-480 pixel screen is capable of displaying 640 distinctdots on each of 480 lines, or about 300,000 pixels.
A file extension (or simply "extension") is the suffix at the endof a filename that indicates what type of file it is. Forexample, in the filename "myreport.txt," the. TXT is the fileextension. It indicates the file is a text document. Some otherexamples include.DOCX, which is used for Microsoft Worddocuments, and .PSD, which is the standard file extension forPhotoshop documents. Most file extensions are 3 letters
